The file picker and Files modal only render filenames and metadata, but
searchFiles()/getFiles() never passed content=false, so the backend
serialized data.content (full extracted text) of every file into each
response. On instances with many large documents this turns a metadata
list into tens of MB per request, re-issued on every picker keystroke.
The backend already supports content=false on GET /files/ and
GET /files/search; this just makes the list/search callers opt out of the
payload by default. The param stays overridable for callers that need it.

A chat created in place (new chat -> first message) keeps chatIdProp
undefined because the URL is swapped via history.replaceState without a
remount, so none of the chatIdProp-gated updateLastReadAt paths fire and
the chat is never persisted with a last_read_at. Starting another new
chat via initNewChat reset $chatId without marking the outgoing chat
read, so on refresh updated_at > last_read_at (NULL) and the chat shows
as unread in the sidebar.
Mark the outgoing chat read in initNewChat, mirroring navigateHandler.
Fixes#25108

validate_url() calls socket.getaddrinfo() for SSRF protection, which
blocks the event loop for 100-700ms per DNS lookup. This affects:
- Image generation (get_image_data) — every external image URL
- Image editing (load_url_image) — every external image URL
- OAuth profile pictures (_process_picture_url) — every login
- Webhook delivery (post_webhook) — every notification
- Image base64 conversion (get_image_base64_from_url) — chat images
Wrap all 5 async call sites in asyncio.to_thread() so DNS resolution
runs in the thread pool. The event loop remains free to serve other
requests during the lookup.
Benchmark (3 domains, 3 trials averaged):
- BEFORE: max jitter 479ms, 1 blocked ping per trial
- AFTER: max jitter 1ms, 0 blocked pings (324x improvement)

get_event_call() routed execute:python / execute:tool events to a client-supplied session_id after only checking the session was connected, not that it belonged to the requester. Verify the target session is owned by the requesting user (metadata user_id) before delivering, so a client cannot route code/tool execution into another user's session.

The Azure TTS handler (_tts_azure) interpolated the user-supplied voice,
and the locale derived from it, into the SSML xml:lang and <voice name>
attributes without XML-escaping, while the text body was already escaped
(2e75c6dbd). Escape both attributes too, so every user-derived value in
the SSML document is consistently encoded.

* feat(calendar): add repeat/recurrence dropdown to event modal
* fix(calendar): anchor recurring event expansion to event start date
The expand_recurring_event() utility used the view range start as dtstart,
causing FREQ=WEEKLY events to land on the wrong day of the week. Use the
event's original start date instead so recurrence patterns stay correct.
The web-ingest probe in get_content_from_url validated the URL at resolve
time (validate_url) but then fetched with a bare requests.get, which
re-resolves the hostname at connect time. An attacker-controlled name
server can answer with a public IP during validation and an internal IP
at connect, reaching cloud metadata / loopback / internal services (blind
always; binary content-types are read back to the caller). The
connection-layer guard (#24759) that closes this for the SafeWebBaseLoader
path was never mounted on this probe.
Route the probe through the same _SSRFSafeAdapter the loader uses, so the
resolution that feeds the TCP connect is re-validated against the
global-IP check.

has_collection did `collection_name in self.client.list_collections()`,
but chromadb's list_collections() returns Collection objects (1.x), not
name strings — so the membership test is always False, even when the
collection exists. Compare against the collection names instead (with a
hasattr guard tolerating versions that yield plain names).
Found via the dependency-contract test suite (unit/deps/test_chromadb.py).

* Extend the already-fixed/monitoring rule to public PRs and credit
Broaden the rule from "already fixed" to also cover issues already being fixed in
the open (e.g. an open pull request), extend the commit-monitoring pattern to PRs,
and fold in the credit consequence on provable grounds rather than an unprovable
bad-faith claim: a report of an already-public, already-fixed-or-being-fixed issue
filed strictly last is a duplicate we cannot distinguish from scraping, so it earns
no advisory. Credit belongs to whoever found or fixed it, who forfeits it by
disclosing publicly instead of reporting confidentially first — so a public fix
earns no advisory and no credit for anyone.

* Remove Rule 14 (One Vulnerability Per Report)
The one-CVE-per-vulnerability constraint it restated is a CVE Program counting
rule, already binding through the "Alignment with the CVE Program" section.
Dropping the standalone rule removes the duplication; bundled reports are still
split on that basis when they arise.

_upload_file_async built its multipart body with
`aiohttp.streams.FilePayload(...)`, which no longer exists in aiohttp
(payload classes live in aiohttp.payload, and there is no FilePayload).
The reference sits inside a lazy closure, so import succeeds and only the
async Mistral OCR file-upload path blows up at runtime with
AttributeError on every call.
Mirror the working sync path: open the file in a context manager and let
MultipartWriter.append(file_obj, {...}) build a streaming
BufferedReaderPayload, with the POST issued inside the open() block so
the handle stays valid for the whole upload. Preserves the streaming /
memory-efficiency intent.
Found via the dependency-contract test suite (unit/deps/test_aiohttp.py),
which pins aiohttp.streams.FilePayload as absent.
constants.py subclassed opentelemetry.semconv.trace.SpanAttributes, which
is deprecated since semconv 1.25.0 (emits a DeprecationWarning; the pinned
0.63b1 has it live). Source the legacy span-attribute keys from the
non-deprecated _incubating attribute modules instead:
http.url / http.method / http.status_code <- _incubating http_attributes
db.name / db.statement / db.operation <- _incubating db_attributes
The stable http module renamed these (http.request.method, ...), so only
the incubating module preserves the original values. Custom keys
(db.instance/type/ip/port, error.*, result.*) stay literals.
Verified: emitted attribute keys are byte-identical before/after for every
key instrumentors.py reads, and importing constants no longer emits a
DeprecationWarning.
Replace per-message database queries with batch IN-clause queries in
channel message handlers. This eliminates the N+1 query pattern that
caused ~102 queries per channel page load (50 messages × 2 queries each).
Changes:
- Add get_reactions_by_message_ids() to MessageTable: single query
fetches all reactions for multiple messages using IN clause with
User JOIN, returns dict[message_id, list[Reactions]]
- Add get_thread_reply_counts_by_message_ids() to MessageTable: single
GROUP BY aggregate query returns (count, max_created_at) per parent,
replacing full object loads just to call len()
- Refactor get_channel_messages(): 102 → 4 queries per page
- Refactor get_pinned_channel_messages(): 22 → 3 queries per page
- Refactor get_channel_thread_messages(): 53 → 4 queries per page
- Refactor send_notification(): N+1 membership check → batch set lookup
pydub imports the stdlib `audioop`, removed in Python 3.13, so audio
preprocessing would break there. requires-python is already capped at
< 3.13; this one-line pointer flags what to handle (audioop-lts, or drop
pydub) before raising that cap.
* chore: bump Python backend dependencies, drop unused peewee
Minor/patch + reviewed major bumps across requirements.txt,
requirements-min.txt, pyproject.toml and uv.lock; playwright image bumped in
docker-compose.playwright.yaml. peewee/peewee-migrate removed (zero imports).
Security-relevant: cryptography 46->48, authlib 1.6.10->1.7.2, PyJWT 2.11->2.13,
requests 2.33.1->2.34.2, RestrictedPython 8.1->8.2, pillow 12.1.1->12.2.0.
Reviewed majors: redis 7->8, pymilvus ->2.6.14, azure-search-documents 11->12,
chardet 5->7, unstructured 0.18->0.22, pycrdt 0.12->0.13.
Testing:
- Resolution: `uv lock` resolves the full bumped set with no conflicts; uv.lock
regenerated to match (peewee dropped, every pin including
azure-search-documents==12.0.0 resolves).
- Per-dependency contract tests (external tests repo, unit/deps/): 105 files,
2205 passed / 6 skipped, ruff-clean. One file per dependency pins the symbols,
signatures and behaviour the backend actually uses, so an API removal/rename in
a bumped version fails loudly instead of at runtime. Offline/deterministic.
- End-to-end embed->retrieve test driving transformers + sentence-transformers +
chromadb together through Open WebUI's real RAG path (cached model, in-memory
chroma, semantic retrieval asserted).
- Install/startup/health resolution gate added to the dep-bump workflow and the
integration suite (uv/pip resolve + uvicorn /health + Playwright dev visibility).
- Bugs surfaced while testing each got an isolated fix branch + regression test:
Mistral OCR aiohttp FilePayload (#25779), chroma has_collection (#25780),
aiocache per-user model-cache key (security), otel semconv deprecation,
pydub/audioop <3.13 note.

* Bump python-multipart 0.0.22 -> 0.0.27 (CVE-2026-42561, CVE-2026-40347)
0.0.22 is affected by two DoS CVEs in the multipart parser that
Starlette/FastAPI run for every multipart/form-data request, so any
authenticated user hitting an upload endpoint can trigger them:
- CVE-2026-42561: unbounded part-header count/size -> CPU exhaustion (fixed 0.0.27)
- CVE-2026-40347: large multipart preamble/epilogue DoS (fixed 0.0.26)

With blank issues disabled, the New Issue chooser only offered Bug Report and
Feature Request, leaving security reporters no obvious route and nudging them
toward filing vulnerabilities as public issues. Add a contact_links entry that
points to the Security Policy (/security/policy), where the "Report a

reports out of public issues.

Replace the recursive parseJSONString with an equivalent iterative unwrap.
The recursion re-parsed its own already-parsed result until JSON.parse threw;
on scalar JSON values (e.g. "5" -> 5) that recursed until a stack overflow
which was then silently caught — wasted work on every complete tool-call
payload. The loop returns the identical value in all cases (verified
byte-identical across 29 inputs incl. double/triple-encoded and partial JSON)
without the stack churn.
