Two Greptile P2s addressed:
1. (security) The audit-log row for an ``add_team_callbacks`` call would
serialize the entire ``callback_vars`` block — including
``langfuse_secret_key``, ``langsmith_api_key``, and the GCS service
account path — verbatim into ``LiteLLM_AuditLogs``. Anyone with read
access to the audit table could harvest team callback credentials.
Same risk for ``disable_team_logging`` when the team's existing row
has populated ``callback_settings.callback_vars``.
Add ``_redact_callback_secrets``: deep-copies the metadata snapshot
and replaces every ``callback_vars`` value with ``***REDACTED***``.
The keys are kept so an auditor can still see *which* fields
changed. Applied to both before and after snapshots.
2. ``asyncio.create_task`` is fire-and-forget; if the audit-log write
raises (transient DB error etc.) the exception is silently
discarded by the event loop and the audit row is just missing —
the exact gap this PR is closing. Attach a ``done_callback`` that
logs the exception at warning level via ``verbose_proxy_logger`` so
the operator sees there's a gap.
Tests assert that callback values are not present in the serialized
audit payload (both for ``add_team_callbacks`` and for
``disable_team_logging`` when the team's existing row has
populated secrets).
The two mutating endpoints in team_callback_endpoints.py
(``/team/{id}/callback`` POST and ``/team/{id}/disable_logging``) wrote
team metadata without emitting an audit-log row. The disable variant
is the worst case: a logging-control action that itself isn't logged,
so an admin (or compromised admin) could zero out a team's
observability with no forensic trail.
Add ``_emit_team_callback_audit_log`` mirroring the
``store_audit_logs``-gated pattern already used in team_endpoints.py
for /team/new and /team/update. When ``litellm.store_audit_logs`` is
True, both endpoints now emit an ``LiteLLM_AuditLogs`` row capturing
the calling user, the API key, and the before/after team metadata.
When the flag is False the helper is a no-op, so non-Enterprise
deployments are unaffected.
The ``litellm_changed_by`` header is now also accepted on
``/team/{id}/disable_logging`` to match the existing
``add_team_callbacks`` shape; the header is optional so existing
callers are unaffected.
Variant scope: the file has three endpoints — both mutating variants
are now logged. The read-only ``GET /team/{id}/callback`` is unchanged.
Other unlogged callback / logging-control admin endpoints elsewhere in
the proxy (e.g. ``/cache/settings``, ``/config_overrides/hashicorp_vault``)
are out of scope here and would be addressed in a separate PR.
Tests cover both endpoints in both ``store_audit_logs`` states and
verify that the captured before/after metadata reflects the actual
mutation, plus that the ``litellm-changed-by`` header overrides the
auth user_id when supplied.
Greptile P2: the bypass removal in update_team_member_permissions had
no dedicated regression test. Adds an integration-style test that
posts to /team/permissions_update as a non-admin caller while
``_is_available_team`` is mocked True, and asserts a 403 — pinning
the bypass-removal against future regressions in the same way the
new member-add unit tests pin the self-join enforcement.
Two paths previously treated ``_is_available_team`` as a blanket
authorization bypass — the function was meant to let standard users
self-join a public team but was wired into the broader admin gate
without bounding the action being performed. Three concrete
exposures resulted:
1. ``/team/member_add``: the bypass let an unprivileged caller add
themselves as a Team Admin, or add an arbitrary other ``user_id``
into the team.
2. ``/team/permissions_update``: the same bypass let any authenticated
user overwrite a team's ``team_member_permissions`` array, mutating
the access policy for every member.
3. (Read endpoint ``/team/permissions_list`` is unchanged — it leaks
read-only policy state to non-members but is out of scope of the
advisory's recommendation; tracking separately.)
This commit:
- Splits ``_validate_team_member_add_permissions`` into early-return
admin checks followed by an available-team self-join branch that
enforces ``member.user_id == caller.user_id`` AND
``member.role == "user"`` for every member entry in the request.
The bulk shape (``member: List[Member]``) is checked the same way,
so a list with one valid self-entry plus one ``role=admin`` entry
is rejected. Email-only members are rejected on the self-join
path: matching by ``user_id`` is the only safe primitive at
pre-validation time (resolving email→user_id earlier would let
unauthenticated callers probe user existence).
- Removes the ``_is_available_team`` clause from
``update_team_member_permissions`` entirely. Only proxy / team /
org admins can update permission policies.
Tests:
- Update the two existing ``_validate_team_member_add_permissions``
unit tests to pass the new ``data`` argument.
- Add six regression tests covering the privesc shape (role=admin),
the cross-user-injection shape (other user_id), the no-caller-uid
fail-closed case, the email-only rejection, and the bulk shape.
- ``test_team_endpoints.py`` 133/133 pass.
Strip module-level docstrings and per-test/per-block prose from the
LIT-2642 fix and tests. Keep one short comment in each streaming site
that flags the GeneratorExit-vs-Exception subtlety, since that's the
non-obvious reason the flush lives in finally rather than after the loop.
Pure cleanup; no behavior change. All 12 regression tests still pass.
Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com>
When a client disconnects mid-stream from a Bedrock pass-through endpoint,
Starlette calls aclose() on the async generator, raising GeneratorExit
(a BaseException, not Exception) at the suspended yield. The previous
`except Exception` blocks in _async_streaming/_sync_streaming
(litellm/passthrough/main.py) and PassThroughStreamingHandler.chunk_processor
did not catch GeneratorExit, so the post-loop flush that hands collected
raw bytes to async_flush_passthrough_collected_chunks /
_route_streaming_logging_to_handler never ran. All per-chunk usage data
was silently dropped, undercounting spend for interrupted Bedrock invoke
and converse streams.
Move the flush into a finally block in all three sites and guard with a
`flush_scheduled` flag so the success path still flushes exactly once.
Also pull raise_for_status() out of the chunk-collection try block in
_async_streaming so 4xx/5xx responses still raise and don't enter the
flush path with zero bytes (preserving the behavior tested by
test_async_streaming_error_propagation.py).
Add regression coverage:
- test_async_streaming_flushes_on_client_disconnect
- test_async_streaming_flushes_on_upstream_exception_with_partial_data
- test_sync_streaming_flushes_on_early_close
- test_chunk_processor_logs_on_client_disconnect
plus baseline tests for normal completion and the 4xx no-flush path.
Fixes LIT-2642.

* chore(auth): validate clientside api_base against SSRF guard; clear admin secrets on base override
Two related issues with how the proxy handles client-supplied
``api_base`` / ``base_url`` overrides on chat-completion requests:
1. **SSRF gate bypass** — ``check_complete_credentials()`` returned
``True`` for any non-empty ``api_key``, allowing the
``is_request_body_safe`` ``banned_params`` loop to admit ``api_base``
/ ``base_url`` values that point at private (RFC 1918), loopback,
link-local, or cloud-metadata addresses. Now: when the gate sees a
client-supplied ``api_base`` / ``base_url``, it runs the URL through
``litellm_core_utils.url_utils.validate_url`` (DNS-resolves, blocks
internal/IMDS/LL networks, defends against rebinding). Rejection
raises with a clear message.
2. **Admin-config leak on base override** —
``get_dynamic_litellm_params`` only carried the three clientside keys
(``api_key``, ``api_base``, ``base_url``) from request to upstream
call. Other admin-configured fields on ``litellm_params`` —
``organization``, ``extra_body``, ``extra_headers``, ``api_version``,
``azure_ad_token``, AWS / Vertex creds, etc. — flowed through
unchanged. With base redirected to a client-controlled server, those
admin secrets were sent to the attacker. Now: when ``api_base`` /
``base_url`` is in ``request_kwargs``, drop those admin-config
fields from ``litellm_params`` unless the caller re-supplied them.
Tests cover the SSRF-target rejection per URL field, the admin-secret
clearing on base override, the don't-clear case when only ``api_key``
is overridden (BYOK pattern), and the don't-overwrite case when the
caller resupplies fields like ``organization`` themselves.

* chore(vertex-batches): wrap api_base GET in safe_get for defense-in-depth
The vertex batches status-poll fetches an attacker-influenceable
``api_base`` URL with a raw ``sync_handler.get()``. The proxy auth gate
already validates clientside ``api_base`` before reaching this sink, so
the proxy flow is covered. This adds the per-sink wrap so SDK callers
and any future code path that bypasses the proxy gate pick up the same
SSRF defense from ``url_utils.safe_get``.
Operators with a legitimate private Vertex base can either allowlist
the host via ``litellm.user_url_allowed_hosts`` or disable validation
with ``litellm.user_url_validation = False``.

* refactor(auth): hoist url_utils import; derive admin-config field list from CredentialLiteLLMParams
/simplify pass:
- Move ``from litellm.litellm_core_utils.url_utils import SSRFError, validate_url``
to module top in ``proxy/auth/auth_utils.py``. CLAUDE.md prefers
module-level imports unless avoiding a circular dependency, and
there's no cycle here (``url_utils`` doesn't depend on ``proxy.auth``).
- Replace the hardcoded ``_ADMIN_CONFIG_FIELDS_TO_CLEAR_ON_BASE_OVERRIDE``
literal with ``_admin_config_fields_to_clear_on_base_override()`` that
derives the typed-field portion from
``CredentialLiteLLMParams.model_fields``. Adds three fields the
hardcoded list missed (``aws_bedrock_runtime_endpoint``,
``watsonx_region_name``, ``region_name``) and stays in sync as new
provider fields are declared on the model. The kwargs-only set
(``organization``, ``extra_body``, ``azure_ad_token``, ``aws_session_token``,
``aws_sts_endpoint``, ``aws_web_identity_token``, ``aws_role_name``, …)
remains explicit since those fields aren't on the typed model.

* fix(auth): close field-echo bypass; gate URL check on toggle; cover async batch path
Three issues from review:
1. ``get_dynamic_litellm_params`` used ``if field not in request_kwargs:
pop`` to clear admin-set provider config when the caller redirected
``api_base``. A caller could *echo* any clear-list field name (with any
value, including an empty string) to skip the pop, leaving the admin's
value in ``litellm_params`` to be forwarded to the redirected upstream.
Fix: always pop, then write the caller's value back if they resupplied
the field.
2. ``check_complete_credentials`` called ``validate_url`` directly. That
helper doesn't itself consult ``litellm.user_url_validation``; the
toggle is honoured by ``safe_get`` / ``async_safe_get``. Mirror that
here so admins who explicitly disabled URL validation aren't blocked
at the proxy boundary.
3. ``VertexAIBatchesHandler._async_retrieve_batch`` still used a bare
``await client.get(api_base, ...)`` while the sync sibling was wrapped
in ``safe_get``. Wrap the async call in ``async_safe_get`` so SDK
callers on the async path get the same DNS-rebind / private /
cloud-metadata defenses as the sync path.
Tests:
- ``TestCheckCompleteCredentialsBlocksSSRF`` is now mock-only; an autouse
fixture flips the toggle on, ``validate_url`` is patched in the
parametrized blocking tests, and the positive path no longer makes a
real DNS call to api.openai.com.
- ``test_skips_url_validation_when_toggle_is_off`` documents the new
toggle-off behaviour and asserts ``validate_url`` is not called.
- ``test_caller_resupplied_value_overrides_admin_value_on_base_override``
replaces the prior test that asserted the buggy
preserve-admin-value-on-echo behaviour.
- ``test_field_echo_does_not_preserve_admin_value`` is a focused
regression test for the empty-string echo vector.

* fix(auth): close provider-confusion credential exfil; expand banned-params; cover OCI
Three additions on top of the entry-point URL gate so the cluster is
fully closed against caller-supplied ``api_base`` redirection:
1. ``get_llm_provider_logic.py`` matched registered openai-compatible
endpoints against ``api_base`` with an unanchored substring search
(``if endpoint in api_base:``). A caller could pass an api_base like
``https://attacker.com/api.groq.com/openai/v1`` to coerce the proxy
into reading ``GROQ_API_KEY`` from the environment and forwarding it
as a Bearer credential to the attacker's host. Replaced with parsed-
URL semantics (hostname exact-match plus segment-bounded path-prefix)
in a new ``_endpoint_matches_api_base`` helper.
2. ``is_request_body_safe`` rejects ``api_base`` / ``base_url`` /
``user_config`` / a handful of AWS / vertex fields, but the list
omitted three other endpoint-targeting fields:
* ``aws_bedrock_runtime_endpoint`` — Bedrock endpoint redirect
* ``langsmith_base_url`` / ``langfuse_host`` — observability callback
hostnames; attacker-controlled values exfiltrate the entire request
payload (incl. message content) via the logging hook.
Added all three to the blocklist.
3. ``_admin_config_fields_to_clear_on_base_override`` derives its typed-
field list from ``CredentialLiteLLMParams.model_fields``, which does
not declare any of the OCI provider's auth fields. Added
``oci_signer``, ``oci_user``, ``oci_fingerprint``, ``oci_tenancy``,
``oci_key``, and ``oci_key_file`` to the kwargs-only fixed list so
they are cleared on caller-redirected ``api_base`` like the AWS /
Azure / Vertex equivalents.
Tests:
- ``TestEndpointMatchesApiBase`` — direct unit tests on the new
matcher: legitimate provider URLs (5 shapes) match; attacker
smuggling via path injection, suffix label, prefix label, userinfo
``@`` injection, and path-segment lookalikes (7 shapes) do not.
- ``TestGetLlmProviderRejectsAttackerSmuggledApiBase`` — end-to-end
invariant that ``GROQ_API_KEY`` is never read against an attacker-
controlled host while the legitimate ``api.groq.com`` path still
resolves the provider correctly.
- ``TestIsRequestBodySafeBlocksEndpointTargetingFields`` — parametrized
coverage that each of the three new banned-params raises a clear
rejection naming the offending field.

* fix(auth): remove implicit api-key bypass + add posthog/braintrust/slack to blocklist
The historical ``check_complete_credentials`` clause inside
``is_request_body_safe`` was a third, *implicit*, *caller-controlled*
BYOK path: any caller that supplied a non-empty ``api_key`` caused the
entire banned-params blocklist to be skipped. That turned every missing
entry on the blocklist into an exploitable SSRF / credential-exfil hole
and is the root cause of the chain of api_base advisories that have
been re-discovered with each new integration:
* GHSA-jh89-88fc-qrfp (critical, triage) — env-var exfil via api_base
* GHSA-3frq-6r6h-7j64 (high, triage) — admin org / extra_body leak
* veria-admin Dv_m860l, b_yRJeQ5, stN90yjP, LBlyOAc8, U2TD78kg —
variations on "list X is missing field Y"
Two explicit, admin-controlled BYOK paths already exist and remain:
``general_settings.allow_client_side_credentials = true`` (proxy-wide)
and ``configurable_clientside_auth_params: [...]`` per deployment.
Removing the implicit bypass converts the failure mode of a missing
blocklist entry from "live credential leak" to "predictable 400 with
a clear remediation message," which is the structural fix.
Also adds the three remaining endpoint-targeting fields the dynamic
callback layer reads from request body: ``posthog_host``,
``braintrust_host``, ``slack_webhook_url``. ``slack_webhook_url`` in
particular was a direct exfil channel (caller-set webhook → proxy
mirrors every request to attacker's Slack).
Tests:
- ``test_api_key_does_not_bypass_blocklist`` — parametrized regression
asserting api_key=anything no longer skips the gate for any of the
five highest-risk fields.
- ``test_admin_opt_in_proxy_wide_still_allows`` — confirms the
documented BYOK opt-in still works.
- Extends ``test_endpoint_targeting_field_in_request_body_is_rejected``
to cover posthog / braintrust / slack.

* fix(auth): block sagemaker_base_url, s3_endpoint_url, deployment_url
Provider-specific endpoint overrides surfaced by a wider audit of
``optional_params`` consumers in ``litellm/llms/``. Same threat as
``api_base``: a caller-supplied value redirects the outbound request
to an attacker host.
* ``s3_endpoint_url`` — read in ``litellm/llms/bedrock/files/transformation.py``
to build the S3 upload URL for Bedrock files. Caller redirects file
uploads to attacker-controlled S3.
* ``sagemaker_base_url`` — read in ``litellm/llms/sagemaker/{chat,completion}/*``.
Caller redirects SageMaker traffic. This is the primary vector
described in veria-admin mNqEBBtG.
* ``deployment_url`` — popped in ``litellm/llms/sap/chat/transformation.py``.
Caller redirects SAP deployment requests.
Tests parametrize ``test_endpoint_targeting_field_in_request_body_is_rejected``
to cover the three new fields.

Read user_id and team_id from the request's litellm_params metadata when
fabricating the UserAPIKeyAuth handed to the managed_files hook, so
batches created via passthrough are attributed to the real requester
instead of a hardcoded fallback. Adds parametrized regression coverage
for both the populated-metadata and empty-kwargs cases.
Use key-in-dict membership instead of truthy value lookup so explicitly
supplied empty/falsy payloads still trigger the permission check.
Adds parametrized regression coverage across all gated keys.
- Proxy decoded `model` from the encoded batch_id but never passed it
to `litellm.aretrieve_batch`.
- Without `model` in kwargs, litellm cannot load `BedrockBatchesConfig`
and falls into the legacy provider switch, which 400s for bedrock.
- Fix: set `data["model"] = model_from_id` before the litellm call in
the SCENARIO 1 (encoded batch_id) branch.
- Also corrects the error string in
`_handle_retrieve_batch_providers_without_provider_config` (said
`'create_batch'` despite being raised from the retrieve path).
- Adds tests covering retrieve + file_content round-trip for bedrock-
encoded IDs.
Three issues surfaced in review of the previous commit:
1. **Veria — Medium**: ``litellm_params`` carries a nested
``litellm_embedding_config`` dict (auto-resolved from the model
registry on create / update) which itself holds ``api_key`` /
``aws_*`` / ``vertex_credentials``. The previous redactor only
inspected top-level keys, so the nested values passed through
unredacted. Recurse into nested dicts.
2. **Greptile — P2**: when ``litellm_params`` is a JSON-serialized
string (the in-memory registry occasionally stores it that way), the
previous redactor silently no-op'd via the ``isinstance(..., dict)``
guard and echoed the raw payload back. Now: parse, redact, re-serialize.
If the string is not valid JSON, replace it with the redaction
sentinel rather than echo it.
3. **mypy** flagged ``_redact_sensitive_litellm_params``'s
``Optional[Dict[str, Any]]`` signature as incompatible with the
``object``-typed call site. Widened to ``Any -> Any`` to reflect the
actual contract (the function now handles dict / str / None / other).
Also fixes a related test regression in
``test_remove_sensitive_info_from_deployment_with_excluded_keys``: the
``"credentials"`` plural addition to ``SensitiveDataMasker`` defaults
caused the first call (without ``excluded_keys``) to mutate the input
dict's ``litellm_credentials_name`` to a masked value. The second call
(with ``excluded_keys``) then saw the already-masked value rather than
the original. Construct fresh input for each call.

Two architectural extensions to the credential-redaction in the previous
commit:
1. ``/vector_store/update`` had two gaps:
- No per-store access control. Any authenticated principal that
passed the premium-feature gate could mutate *any* vector store,
including stores belonging to other teams.
- The response returned the full DB row including ``litellm_params``,
so the caller could read another team's persisted provider
credentials by submitting a no-op metadata change.
Mirror the access-control check ``/vector_store/info`` already
performs (``_check_vector_store_access`` against the existing row),
redact ``litellm_params`` in the response, and add an
``except HTTPException: raise`` guard so the 403/404 responses don't
get rewritten as 500 by the catch-all.
2. ``SensitiveDataMasker``'s default ``sensitive_patterns`` set used
segment-exact matching, so ``credential`` matched ``vertex_credential``
but not ``vertex_credentials`` (the actual Vertex field name). The
previous commit worked around this with a per-call extension; this
commit puts the plural in the upstream defaults so every caller
(Redis config dump, MCP debug headers, cache routes, ...) gets the
correct behavior. The local override in
``vector_store_endpoints/management_endpoints.py`` is removed.
Also updates ``test_excluded_keys_exact_match`` which relied on
``credentials`` *not* being a sensitive pattern to demonstrate
case-sensitive ``excluded_keys`` matching. The intent of the test
(case-sensitive match) is preserved; the assertion now reflects that
when ``excluded_keys`` fails to apply (wrong case), the field falls
through to standard pattern-based masking instead of being passed
through unchanged.

/simplify pass:
- Remove the single-call-site ``_redact_vector_store`` wrapper. Inline
the two-line redaction at its only caller in ``list_vector_stores``;
``get_vector_store_info`` was already calling the inner helper directly.
- Inherit ``SensitiveDataMasker``'s default sensitive-key set instead of
duplicating the 12-element list, then add only the plural
``credentials`` extension. Won't drift if upstream defaults change.
- Trim the over-explained docstring on ``_redact_sensitive_litellm_params``
to a one-paragraph summary; the WHY (credential-leakage class) belongs
in the commit message, not in every consumer's IDE tooltip.

``LiteLLM_ManagedVectorStore.litellm_params`` carries the upstream provider
credential — OpenAI ``api_key``, AWS ``aws_access_key_id`` /
``aws_secret_access_key``, GCP ``vertex_credentials``, etc. ``GET
/vector_store/list`` and ``POST /vector_store/info`` return these
verbatim to any authenticated principal. Because both routes are in
``openai_routes``, ``RouteChecks.is_llm_api_route`` short-circuits the
standard role gate, so even read-only users and narrowly-scoped keys can
read every stored credential.
Replace credential-bearing values with the ``REDACTED_BY_LITELM``
sentinel in both responses while preserving non-secret keys
(``api_base``, ``region``, ``model``, ``api_version``) so callers can
still see *which* upstream is configured. Detection reuses
``SensitiveDataMasker.is_sensitive_key`` with the default heuristics
plus the plural ``credentials`` pattern (covers Vertex's
``vertex_credentials`` field, which the singular ``credential`` pattern
misses on segment-exact matching).
Applied at:
- ``list_vector_stores`` (``GET /vector_store/list``,
``GET /v1/vector_store/list``)
- ``get_vector_store_info`` (``POST /vector_store/info``), both the
in-memory-registry path and the prisma-DB fallback

Two related changes to how the master-key auth path interacts with
downstream consumers of UserAPIKeyAuth.api_key:
1. The master-key auth branch in user_api_key_auth.py now sets
`valid_token.api_key` to a stable alias
(`LITELLM_PROXY_MASTER_KEY_ALIAS = "litellm_proxy_master_key"`) instead
of the raw master key. Downstream consumers — spend logging,
Prometheus metrics, audit trails, rate limiting, cost tracking — now
receive the alias instead of the master key (which they would
previously hash and propagate). Neither the raw master key nor its
hash flows past the auth layer.
2. `_is_master_key` in spend_tracking_utils.py is reduced to a strict
raw-only constant-time comparison. The hashed form is no longer
considered equivalent.
Side effects:
- The two hash-detection blocks in `get_logging_payload` are removed.
They were re-detecting the master key per spend-log write to swap in
the alias; that detection happens once at the auth layer now.
- The `disable_adding_master_key_hash_to_db` general setting becomes a
no-op. Operators can remove it from their config; existing config is
still accepted.
- Operator dashboards that filter Prometheus metrics by the master-key
hash will need to switch to the `api_key="litellm_proxy_master_key"`
label.
