fix(secret_managers)!: resolve oidc/file and oidc/env refs in admin-configured api_key per request (#47341)
* fix(secret_managers): resolve oidc/file and oidc/env refs in admin-configured api_key per request

An api_key set to oidc/file/<path> or oidc/env/<VAR> in a credential_list entry or a deployment's
litellm_params was sent upstream as literal text, so every call answered 401. The SDK client wrapper
now reads the referenced file or env var on each call and never writes the token back, so a rotated
token is used on the next call. The existing server-owned federation gates treat an oidc/ api_key as
server-owned by value, so a request body, a non-admin credential or model write, user_config, fallback
targets and routing tier params can never carry or name one. Other oidc/ kinds answer 400

* fix(secret_managers): strip only the leading oidc/ from a secret reference

A token file under a directory named oidc resolved to the wrong path, because every oidc/ in the reference was removed

* fix(auth): refuse oidc/ api_key refs in advisor tools and scope the route gates to them

The advisor tool's own api_key now answers a 400 when it holds an oidc/
reference, since its sub-call runs through the client wrapper that resolves
one. Stored fallback targets, auto-router tiers and user_config refuse only an
oidc/ api_key, inline or through the credential they name, so their workload
identity federation handling stays as it was. Provider model discovery for a
wildcard deployment resolves the reference before calling the provider.

* fix(auth): allow admin oidc api_key on deployment writes, resolve refs on discovery, batch probe and realtime health, refuse client api_base on oidc deployments

* fix(utils): resolve oidc api_key refs only from admin-configured sources

Mark an oidc/ api_key read from a proxy-level deployment or a stored
credential, and resolve only that marked value. Team deployments, prompt
templates, nested configs and a direct SDK api_key send the text as
written. An unsupported reference kind raises a 401 so the router fails
over to the group's next deployment.

* fix(utils): send a credential's oidc token only to its own api_base host

A stored credential's oidc/ api_key now resolves only for the scheme, host and port of the
credential's own api_base or base_url, so a team model or vector store that names the
credential with another api_base gets a 401 and that host gets nothing. Saving a team model
with an inline oidc/ api_key answers 400, since team rows never resolve one.

* fix(proxy): send an admin oidc api_key only to the hosts configured beside it

Every admin oidc/ reference now carries the origins of the host params set beside it, checked for api_base, base_url and the Bedrock, S3, SageMaker and deployment_url params. Token counting reads the reference only when it calls the provider, answering 401 when it cannot, and pass-through 401s redact internal paths.

* fix(proxy): redact the token path from token count auth errors

* test(security): cover token count, Bedrock endpoint, api_base update and pass-through path redaction for oidc api_key refs

* fix(proxy): redact the token path from secret reference errors where they are raised

* fix(proxy): keep the secret reference's path out of the error a caller sees

The 401 for an unreadable oidc api_key or pass-through credential now names only
the reference kind and a fixed reason, so a token path under /run/secrets or a
custom credential dir never reaches the caller, while the server log keeps the
full reference for the operator

* fix(secret_managers): strip line breaks from the logged secret reference

A reference holding a newline can no longer forge a server log line

* fix(secret_managers): label an unknown oidc reference kind instead of echoing it

An api_key such as oidc/env_MY_VAR (a typo for oidc/env/MY_VAR) came back in
full in the caller's 401 and in the spend log, since the kind was whatever
text followed oidc/. A kind get_secret does not know now reads
oidc/<unknown kind>. The relative-path hint uses oidc/file//<absolute path>,
which the client-message redaction on chat routes leaves whole.

* test(health): run the real model auth check in the oidc test connection test

* test(secret_managers): read an oidc/file token stored under a directory named oidc

* fix(secret_managers): count a URL in the model name as an upstream host for oidc api_key references

A huggingface/* wildcard call could name its own endpoint URL as the model and
receive the resolved token. The origin check now treats a URL in the model as
a host the reference must allow. The integration contract also reads the
proxy's own database instead of the pytest worker's.

* fix(secret_managers): treat a default port as explicit when matching an oidc api_key origin

A credential on https://api.mistral.ai refused a call to https://api.mistral.ai:443,
though both reach the same server. The origin check now compares scheme, host
and effective port, as assert_same_origin does, and an unparseable api_base is
refused instead of raising. The advisor test sets the real proxy flag instead of
replacing our own helpers.

* test: type the oidc request-body helpers and drive the tier test through mock_response

* fix(secret_managers): refuse an oidc api_key reference whose call drops the configured host

feat(anthropic): workload identity federation and pluggable identity sources (#44448)
* feat(anthropic): workload identity federation and pluggable identity sources

Backend half of #38818 (internal copy of the fork PR #38013), rebuilt as one
commit on top of litellm_internal_staging without the dashboard changes.

Deployments on anthropic/ without a static api_key can exchange an OIDC
workload assertion for a short-lived sk-ant-oat01 token through a shared
RFC 7523 JWT-bearer engine. The assertion comes from a mounted token file,
an env token, a LiteLLM-signed issuer, or Keycloak, chosen per deployment,
per named credential, or through ANTHROPIC_IDENTITY_SOURCE. The federation
fields are server-owned: refused inline in request bodies and on
POST /model/new, proxy-admin only on credentials, and the token exchange
is pinned to api.anthropic.com unless LITELLM_ANTHROPIC_WIF_ALLOWED_HOSTS
adds a host. GET /credentials/{name}/jwks exports the public key set of a
LiteLLM-signed credential for the Claude Console.

The OpenAI federation trio from #39613 rides along on the backend side with
the same server-owned handling.

Fixes #28607
Resolves LIT-6107

* fix(anthropic): let batch-result downloads mint from deployment params and accept host:port allowlist entries

The files handler enabled workload identity on batch-result downloads but never received the
deployment's litellm_params, so a deployment authenticating through a named credential could only
mint from process-wide env vars. It now threads litellm_params through to the auth header the way
the batch retrieve path already does.

LITELLM_ANTHROPIC_WIF_ALLOWED_HOSTS entries written as host:port were read by urlsplit as a scheme,
so the allowlist kept the raw entry while the exchange compared bare hostnames and refused the
gateway. Entries are now parsed as network locations whether or not they carry a scheme.

* fix(types): move the WIF kwargs key sets to a leaf module so the kwargs funnel imports without a cycle

* test(anthropic): pin case-insensitive matching of WIF exchange-host allowlist entries

* fix(anthropic): end workload identity federation errors without a period so the router suffix reads cleanly

* fix(proxy): decrypt stored litellm_params before the WIF write gate

* fix(proxy): hide WIF secret references from /health output

* fix(proxy): keep the proxy error shape on credential endpoint refusals

* fix(proxy): hide identity token file paths from /health output

* fix(anthropic): rename the federation workspace param so Bedrock's anthropic_workspace_id keeps working

The Bedrock Claude Platform route already reads anthropic_workspace_id from
optional_params, so banning that spelling as a server-owned federation
parameter broke a pre-existing client capability. The federation field is now
anthropic_federation_workspace_id (env ANTHROPIC_FEDERATION_WORKSPACE_ID),
which restores the base branch's behavior for Bedrock callers, drops the
Bedrock-specific hint from the refusal message, and deletes the unconditional
ban constant that no longer had a reader

* fix(auth): share one exchanged token across workers reading the same assertion

Anthropic accepts each identity assertion exactly once, so two uvicorn
workers reading the same token file both minting from it means the second
exchange is denied with jti_reused. Minted tokens now land in a per-user
0700 cache directory guarded by a file lock, so workers on the same host
reuse one exchange until the token expires or the assertion rotates. A 401
is only retried when the re-read assertion actually differs, and the denial
hint explains jti_reused. LITELLM_TOKEN_EXCHANGE_CACHE_DIR moves the cache
and an empty value disables it

* fix: keep anthropic federation from being shadowed or leaked

An empty or whitespace-only ANTHROPIC_API_KEY counted as set, so a federated
deployment sent an empty x-api-key on every call instead of minting a token.
Blank values now read as unset, and a real static key on a federated deployment
logs once that it outranks federation and nothing is being federated.

The exchange-host allowlist matched hostnames only, so a second process on
another port of an allowed host was trusted with the workload's identity token.
An entry that names a port now trusts that port alone, while a bare host still
trusts every port.

The shared token store exists so the workers reading one projected token file do
not each spend its single-use jti. A source that mints its own assertion per
exchange shares nothing with another worker, so it no longer writes a live token
to disk for a lookup that can never hit.

* fix: unlink a staged token file a failed write leaves behind

The 401 denial hint now also says federation ignores ANTHROPIC_WORKSPACE_ID, which the Bedrock Claude platform provider already reads.

* refactor: move anthropic jwks derivation behind a provider-owned tagged union

* fix: unlink the staged token file when its write fails at close

A buffered write only reaches the disk when the handle closes, so a full disk surfaces at close and left the staging file behind holding a usable token.

* fix(anthropic): close the staging descriptor before writing the shared token file

* fix(wif): judge federation writes by what they set, not what is stored

The admin gate read the stored deployment, so a team admin lost edit, delete
and Test Connection on any deployment carrying federation params. It now
returns early unless the submitted fields touch the federation surface, and a
Test Connection probe that points the deployment at its own api_base is still
refused, with the 403 no longer wrapped into a 500

The rest of the same review pass: POST /model/new refuses only a blocking
value of `blocked`, so a client that always sends `blocked: false` is not
turned away; a request body can no longer pick which federated identity to
mint as by naming a stored credential; an advisory refresh the executor
refuses disarms the entry instead of wedging the identity until the follower
timeout; the static-key shadow warning resolves its env fallback inside the
cache instead of once per request; credential writes drop nulls before
storing them; the token exchange validates the endpoint URL before reading an
assertion and keeps refusing redirects across a client heal; /health hides
every server-owned federation field from non-admins; and the async create_file
and create_batch paths say which setting is missing when the provider resolves
no URL

* fix(proxy): let a deployment write name a federated credential

reject_federated_credential_reference runs from is_request_body_safe, which
pre_db_read_auth_checks calls on every route, so it also fired on POST
/model/new, /model/update, /model/{id}/update and /health/test_connection. A
proxy admin could no longer attach a federated credential to a deployment over
the API or the Admin UI, leaving a static config.yaml entry as the only way to
configure the feature the rejection told the caller to go configure, and
_reject_non_admin_wif_write never got to make the call it exists to make.

is_request_body_safe now takes the route and skips only the credential-reference
check on the routes that reach can_user_make_model_call. Federation fields typed
inline into a body stay refused everywhere, and a call naming a federated
credential still cannot pick the identity it mints as.

* refactor(proxy): derive health display policy from the federation key sets

The health check module hand-copied the five workload identity fields whose
value is a credential, so a shared proxy surface named provider-specific
parameters and a newly added secret-bearing field would have gone on being
displayed until someone remembered both places

WIF_SECRET_BEARING_KEYS now sits beside the key sets it splits out of,
types/utils derives secret_bearing_wif_litellm_params from it, and the health
layer splats that tuple the same way it already splats the admin-only one

* fix(anthropic_wif): treat blank identity-source fields as unset

* test(proxy): classify the federation params in the credential slot registry

main's registry test (#43298) now fails the build for any credential-named
deployment param without a classification. The five federation fields that
carry a token, a token file path, or a signing or client secret reference are
Unplanted, matching WIF_SECRET_BEARING_KEYS; the four remaining Keycloak
settings name a URL, a client id, an auth method, or a scope and are NotSecret

* fix(anthropic_wif): declare federation params as owned connection leaves and chart their metrics

Register the 18 Anthropic and 3 OpenAI federation params as frozen
ConnectionSettings leaves so the owned-kwarg registry, the kwargs funnel
and the request-body ban list read one declaration. Pass the deployment
api_base through to the count-tokens handler instead of a pre-suffixed
URL, which doubled the /count_tokens path on main's prompt-cache
predictor. Add the five litellm_anthropic_wif_* families to the
all-metrics Grafana dashboard.

* fix(credentials): gate PATCH on WIF fields resolved from model_id

The credential PATCH handler checked server-owned workload identity
federation fields only on the values the caller sent, while a body that
named a deployment through model_id had its credential values resolved
after that check. A non-admin could therefore copy a federated
deployment's WIF fields onto an ordinary credential. Resolve the incoming
values first and run the non-admin gate on them, matching the POST path

* fix(anthropic): count tokens with ANTHROPIC_AUTH_TOKEN through the shared auth header

Count-tokens walked its own credential ladder: a static key, else skip minting when
ANTHROPIC_AUTH_TOKEN is set, else mint a federated token. With only the auth token set it
forwarded nothing and the proxy silently fell back to its local tokenizer while chat on the
same deployment authenticated with that token. The handler now takes the auth header that
AnthropicModelInfo.aget_auth_header resolves, the same ladder chat, files, batches and skills
use, and merges the oauth beta a minted or consumer token carries with the token-counting beta
