Rotating through POST /key/regenerate needs a running proxy, which a refused boot does not have. The refusal now counts the stored values that decrypt under the unsafe key. When there are none it only asks for a new key. When there are some it also asks for LITELLM_MIGRATE_FROM_MASTER_KEY, and the next boot with a safe key re-encrypts them and logs that the variable can be deleted. Leaving the variable set afterwards is a no-op with one notice.
The proxy used to boot with no master key (every request accepted without
authentication) and with sk-1234, the key every example used. It now stops at
startup, before it connects to the database, and prints how to fix it: where the
bad key came from, a copy-pastable command that generates a secure key, and,
when the public key is also encrypting a database, a link to the rotation guide
general_settings.dangerously_allow_unsafe_proxy: true or
LITELLM_DANGEROUSLY_ALLOW_UNSAFE_PROXY=true starts the proxy anyway, for local
development. CI and test boots that rely on sk-1234 or on no key set it
BREAKING CHANGE: deployments with no master key, an empty one, or sk-1234 no
longer start until they set a real key or opt in to the override
The last-known org copy was written only on get_org_object's DB-read path. The
virtual-key auth prefetch fills the same 5s org entry directly, so with keys and
JWTs of one org on the same worker the JWT lookup always hit the cache, never
wrote the copy, and a DB outage turned that JWT traffic into 503s again.
get_org_object_for_request now writes the copy itself whenever this worker holds
none, under the management-object TTL, and get_org_object is back to its shape
on main.
A JWT whose team sits in an org resolves the org on every request, and the
org row is cached for only DEFAULT_IN_MEMORY_TTL seconds while the team and
user rows ride the 60s management-object TTL. A few seconds into a database
outage the org lookup failed closed and that traffic got 503s while the same
request through a virtual key kept succeeding on its cached team.
get_org_object now also keeps a last-known copy of the org row under the
management-object TTL, and get_org_object_for_request serves that copy when
the database is unreachable, so JWT traffic degrades the same way the team
lookup does. A missing copy keeps the previous behaviour: fail closed unless
allow_requests_on_db_unavailable is set.
A project max_budget of 0 was treated as unbudgeted by #41354, while key budgets block at 0 and null is the unlimited value. Drop the <= 0 skip so 0 blocks and null stays unlimited
#41515 added the cost map entry transcribe/StartTranscriptionJob under a
new litellm_provider value "transcribe" without registering that provider
anywhere else, so litellm.models_by_provider had no "transcribe" key.
test_models_by_provider derives its provider set from the cost map itself,
so it went red on main. The user-visible half is that get_provider_models
returned None for the provider, which get_known_models_from_wildcard turns
into an empty list, leaving a transcribe/* key or team grant resolving to
no models.
Mirror the aws_polly registration: an enum member, a model set, an
ingestion branch, and a models_by_provider entry. Amazon Transcribe is
reached through the pass-through route rather than the Add Model form, so
it joins the frozen unlisted set the Add Model drift test tracks.
Adds a projects entry to the team_admin_editable_team_fields setting. When set, team admins (legacy admins list or members_with_roles role admin) can call /project/new and /project/update for the teams they administer. The two routes join self_managed_routes so the endpoint check runs instead of the route gate's blanket 401. /project/delete stays proxy admin only

The lint job failed on one new typing.cast (LIT006) in the cost callback, and the test-quality gate behind it would have failed next on a test whose only assertion inspected a mock (TQ002). project_id is now narrowed with isinstance, and the zero and negative max_budget cases run through the existing parametrized budget test, which asserts the raised error or a clean admit with no alert
* feat(proxy): limit repeated failed Admin UI sign-in attempts
The Admin UI sign-in endpoints accept an unbounded number of password attempts.
All three call authenticate_user, and none of them keeps any record of how many
times a given caller has already been refused, so a misbehaving or misconfigured
client can retry indefinitely at full speed.
A LoginThrottle is now a required argument to authenticate_user, so the accounting
lives at the one function all three endpoints share and a fourth endpoint cannot be
added without deciding what to pass. Failures are counted per username and source
address over a fixed window and further attempts are refused with 429 and a
Retry-After header. The check runs before the database lookup and before the
password comparison, so a refused caller does no further work.
Only genuine credential rejections count. Configuration errors do not, a refused
attempt does not extend the window, and a successful sign-in clears the bucket.
The username is case folded because the user lookup is case insensitive, so casing
cannot multiply the allowance. Both credential rejections now return one identical
message. SSO is unaffected; it never calls this function.
max_failed_login_attempts (10) and failed_login_window_seconds (900) are read from
config.yaml, with LITELLM_DISABLE_LOGIN_RATE_LIMIT to turn the accounting off. They
are deliberately not database backed, so editing YAML always wins and an operator
refused by a bad value can recover.

* fix(proxy): write failed-login counters and their expiry in one Redis call
Use RedisCache.async_increment_with_floor (a single Lua INCRBY + EXPIRE) for the
shared login counters instead of the two-step INCRBYFLOAT then EXPIRE, so a
counter can never be committed to Redis without its expiry. The repair in
_remaining_window now only covers expiries stripped out of band (PERSIST, a
restore) and uses the same atomic call

* fix(proxy): resolve the login rate limit kill switch once per process

unauthenticated sign-in attempt meant a hosted secret manager in read mode

* fix(proxy): count failed sign-ins in Redis alone while it answers
Every worker spends one shared budget and a successful sign-in clears it for all
of them. This worker's own counter is only consulted while Redis raises, so an
outage degrades to per-worker accounting instead of switching the control off

* fix(proxy): keep counting the failed sign-ins Redis missed once it answers again
A guess is recorded in exactly one place, Redis or this worker's own store when Redis
refused it, so the count is the sum of the two. Redis is read through
async_batch_get_counts, which raises on failure, instead of async_get_cache, which
swallows it into None and read as an empty counter

redis_usage_cache explicitly; behavior is unchanged.

* feat(proxy): throttle failed Admin UI sign-ins per source and source/username
Replace the username-global lockout with counters keyed by source address and by
source/username pair. Each has a fixed counting window (60s) and a separate
block TTL (300s). Blocks are soft: a correct password still signs in, wrong
passwords from a blocked key take one of 5 held slots per worker and are held
30s before a 429. Once a pair is blocked its failures stop counting against the
source. The source scope runs only when trusted_proxy_ranges is set, IPv6 is
grouped by /64, and per-source limits accept IP and CIDR overrides with
longest-prefix matching. Redis is authoritative through one Lua script per
failure, with bounded per-worker fallback when Redis raises.

The held-attempt cap ran before the password check, so five parked wrong

pool-full refusal carries the block's remaining time as Retry-After

* feat(proxy): hard-block throttled Admin UI sign-ins with no credential bypass
A blocked source, or source and username pair, is now refused with 429 before the database lookup and password check, in place of the soft block that held wrong guesses for 30 seconds and let a correct password through. The env admin credentials and the master key typed into the login form are refused like any other credential while blocked; recovery is the master key as an API bearer token, which never goes through the sign-in path
trusted_proxy_ranges: [] now means clients connect directly, so the peer address is the source and the per-source limit stays on. Only an unset or malformed value leaves the topology unknown, warns at startup and turns the per-source limit off

The repo rule is that a test must only fail when litellm code changes, never when a vendor updates a price, renames a field, or drops a model. These tests asserted shipped catalog entries directly, comparing lookup results to literals copied from model_prices_and_context_window.json or requiring named entries to exist or be absent, so every cost map sync could break them without any litellm code changing
Tests that exercise real litellm behavior with an injected local model_cost, invariants like backup parity, and assertions on non-lookup code paths are untouched
