Web search results stored as a vector collection were silently dropped
before retrieval when BYPASS_RETRIEVAL_ACCESS_CONTROL is False (the
default). The server-generated web_search file item carries a
'collection_name' but its 'web_search' type is not matched by any
explicit dispatch branch in get_sources_from_items, so it fell through
to the untrusted client-supplied collection_name branch and was ignored.
Add an explicit branch for type == 'web_search' items so the collection
is queried again. Access control is preserved: the collection still
passes through filter_accessible_collections, which already allowlists
web-search-* and bypasses only for admins.
Regression introduced when the retrieval access-control hardening gated
the bare collection_name fallback behind BYPASS_RETRIEVAL_ACCESS_CONTROL.
get_embedding_function runs at import time (main.py), so the empty-engine
+ no-model guard added in 55ca719b raised ValueError during startup and
bricked the instance: a blank embedding model set via the UI made the app
unbootable, with no way back into settings to undo it. Move the check into
the returned coroutine so construction always succeeds and the error only
fires when something actually embeds, surfacing as a clear request error
instead of the old cryptic 'NoneType has no attribute encode'.

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).
_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.
is_string_allowed does endswith() matching and was called with the full URL
(retrieval/web/utils.py) against WEB_FETCH_FILTER_LIST, so a blocklisted host with any
path (https://blocked.example/x) ended with /x, not the host, and slipped through; the
allowlist direction false-rejected legitimate URLs and admitted attacker URLs ending in
an allowed string. The same endswith caused label confusion at the hostname call site
(retrieval/web/main.py): corp.com matched evilcorp.com, 10.0.0.1 matched 110.0.0.1.
Add is_host_allowed(host, ...) matching on DNS label boundaries (host == pattern or
host.endswith('.' + pattern)), called with the parsed hostname at both web-fetch call
sites. is_string_allowed is left unchanged for the unrelated function-name filters
(utils/middleware.py, utils/tools.py).
The separate is_global guard (validate_url / _ssrf_safe_new_conn, active when
ENABLE_RAG_LOCAL_WEB_FETCH is off) already blocks RFC1918/loopback/link-local, so this
restores the admin's intended blocking of specific public hosts.

The connection-layer DNS-rebinding guard (_SSRFSafeResolver / _SSRFSafeAdapter, PR #24759) was
mounted only on SafeWebBaseLoader. Two user-reachable image fetches validate the URL then fetch
it through the shared get_session() pool with the default resolver, so a TTL-0 rebinding answer
that passed validate_url reaches an internal address at connect:
- get_image_base64_from_url (utils/files.py): user image_url on every chat completion.
- load_url_image (routers/images.py, POST /api/v1/images/edit): user-supplied image field.
Add get_ssrf_safe_session() (a one-off aiohttp session mounting _SSRFSafeResolver) and use it
for both fetches, so the connect-time IP is re-validated and a rebound loopback / RFC1918 /
metadata address is rejected. The shared pool is left untouched for the admin-configured
image-generation callers, which legitimately reach internal hosts.

The Qdrant backends implemented delete(ids=...) as a payload filter on
metadata.id, but points are stored with the item id as the Qdrant point id
(see _create_points), and not every point carries an id in its payload.
Memory points store only {created_at} in metadata (KB metadata embeddings
likewise), so deleting a single memory matched nothing and left an orphaned
vector that kept being injected into RAG context.
Delete by point id instead: PointIdsList for the standard backend, and a
tenant-scoped HasIdCondition for multitenancy (point ids are unique, so tenant
isolation is preserved). Filter-based deletion is unchanged.

Firecrawl /search returns either `{"data": [...]}` (flat list — v1, and
what frost19k reported on #23966) or `{"data": {"web": [...]}}` (v2,
current production). The parser only handled the dict shape:
data = response.get('data') or {}
results = data.get('web') or []
On a list-shape response, `data.get('web')` raised AttributeError,
caught by the function's outer try/except, and `search_firecrawl`
silently returned []. Web search worked against v2 endpoints but is one
upstream-format-change away from failing closed again. Accept either.
Open WebUI's collection ACL accepted any unknown name as a
legacy/ephemeral collection. In Milvus multi-tenancy mode that name
becomes the `resource_id` and is interpolated unescaped into a SQL-like
Milvus expression — `resource_id == '<name>'` — so a name like
x' or resource_id != '' or resource_id == 'x
turns the filter into a tautology and returns every tenant's chunks
from the shared collection.
All collection names Open WebUI generates are UUIDs, SHA-256 hex
digests, or fixed-prefix variants of those — they all fit
[A-Za-z0-9_-]. Add a strict format check in
filter_accessible_collections (utils.py) that drops any name outside
that set before any ACL or vector-store lookup, applied even on the
admin bypass path. _validate_collection_access then surfaces the dropped
name as a 403.
As defense in depth, MilvusClient now validates resource_id at every
expression-construction site and escapes single quotes / backslashes in
any other string interpolated into a filter (delete ids, metadata
filter values). Non-string filter values are typed-checked instead of
str()-formatted.

validate_url() resolves DNS to check IPs but discards the result; the
HTTP client resolves again independently. Between those two lookups an
attacker can swap the DNS record from a public IP to an internal one
(DNS rebinding).
Push the IP-is-global check into the actual connection layer so the
validated resolution is the one used for the TCP connect:
- aiohttp (_fetch): _SSRFSafeResolver wraps DefaultResolver and rejects
non-global IPs at resolve time (zero TOCTOU window).
- requests (_scrape): _SSRFSafeAdapter mounts custom urllib3 connection
classes whose _new_conn resolves, validates, and connects to the
validated IP in one shot (zero TOCTOU window).
Both paths respect ENABLE_RAG_LOCAL_WEB_FETCH (skip validation when on).

SafePlaywrightURLLoader validated only the initially submitted URL and
then let the browser follow HTTP redirects and client-side navigations
without re-checking them, so a public URL could redirect into the
internal network (cloud metadata, RFC1918, loopback). Intercept
document-type requests, re-run validate_url on each, and apply the same
redirect policy as the requests loader (blocked unless
AIOHTTP_CLIENT_ALLOW_REDIRECTS). Sub-resource requests pass through
unchanged so page rendering performance is unaffected.

The __main__ block called search_bing() with 4 positional arguments, but
the function requires 5 (subscription_key, endpoint, locale, query,
count). Running `python -m open_webui.retrieval.web.bing` raised a
TypeError and, before failing, silently misrouted every argument. Read
the key/endpoint from environment variables, matching config.py defaults.
Closes#24765

urllib.parse.urlparse and requests/aiohttp disagree on how to split URLs
containing backslash, tab, CR, or LF in or around the netloc. urlparse
treats backslash as part of userinfo and uses what follows '@' as the
host; requests treats backslash as the start of the path and connects
to whatever precedes it. The same URL therefore passes the private-IP
filter (urlparse sees a public host) but reaches an internal target
(requests connects to e.g. 127.0.0.1). End result is an SSRF that the
existing IP block list cannot catch because it's evaluating the wrong
host.
PoC: http://127.0.0.1:6666\@1.1.1.1 — urlparse hostname is 1.1.1.1
(global, passes), requests reaches 127.0.0.1 (loopback).
Reject up front any URL containing one of the four documented parser-
confusing characters before either parser gets a chance to interpret
it. None of these characters is valid in an unencoded URL (\ should
always be %5C, whitespace should be %09 / %0A / %0D), so this is a
pure defensive rejection with no legitimate-input false positives.

validate_url() in retrieval/web/utils.py only validates the initial URL.
The HTTP clients used downstream (sync requests, sync requests via the
parent WebBaseLoader._scrape, aiohttp via load_url_image) followed 3xx
redirects by default and did not re-validate the redirect target against
the private-IP / metadata-IP block list. An authenticated user could
submit a public URL that 302-redirected to an internal address (RFC1918,
127.0.0.1, 169.254.169.254, etc.) and the redirected response was returned
to them, enabling SSRF reads of internal services and cloud metadata.
Three call sites needed allow_redirects=False to match the policy already
enforced on the async _fetch() path:
- SafeWebBaseLoader: override requests_kwargs in __init__ so that the
inherited synchronous _scrape() path passes allow_redirects=False to
self.session.get() (the parent WebBaseLoader uses requests' default
allow_redirects=True).
- get_content_from_url (retrieval/utils.py): pass allow_redirects=False
on the streamed requests.get(...) call.
- load_url_image (routers/images.py, image-edits endpoint): pass
allow_redirects=False on the aiohttp session.get(...) call.
