CWE-918
AllowedServer-Side Request Forgery (SSRF)
Abstraction: Base · Status: Incomplete
The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
4740 vulnerabilities reference this CWE, most recent first.
GHSA-226F-F24G-524W
Vulnerability from github – Published: 2026-06-17 14:10 – Updated: 2026-06-17 14:10Summary
backend/open_webui/utils/oauth.py::_process_picture_url (v0.9.5, lines 1435-1470) calls validate_url(picture_url) on the initial URL only, then invokes aiohttp.ClientSession.get(picture_url, ...) without allow_redirects=False. aiohttp's default is allow_redirects=True, max_redirects=10; the function does not pass the project's AIOHTTP_CLIENT_ALLOW_REDIRECTS env constant either. An attacker with a valid OAuth IdP identity can therefore submit a public URL that 302-redirects to an internal address and read the internal response body via the attacker's own profile_image_url field.
This is the same redirect-bypass class as CVE-2026-45401 (GHSA-rh5x-h6pp-cjj6), on a 6th call site that the v0.9.5 patch missed. CVE-2026-45401's advisory body enumerates exactly five affected paths — SafeWebBaseLoader._scrape, _fetch, get_content_from_url, load_url_image, get_image_base64_from_url — none in utils/oauth.py.
Vulnerable code (v0.9.5)
backend/open_webui/utils/oauth.py, lines 1435-1470:
async def _process_picture_url(self, picture_url: str, access_token: str = None) -> str:
if not picture_url:
return '/user.png'
try:
validate_url(picture_url) # initial URL only
get_kwargs = {}
if access_token:
get_kwargs['headers'] = {'Authorization': f'Bearer {access_token}'}
async with aiohttp.ClientSession(trust_env=True) as session:
async with session.get(picture_url, **get_kwargs,
ssl=AIOHTTP_CLIENT_SESSION_SSL) as resp:
# ^^^^^^^^^^^ no allow_redirects=False
if resp.ok:
picture = await resp.read()
base64_encoded_picture = base64.b64encode(picture).decode('utf-8')
guessed_mime_type = mimetypes.guess_type(picture_url)[0]
if guessed_mime_type is None:
guessed_mime_type = 'image/jpeg'
return f'data:{guessed_mime_type};base64,{base64_encoded_picture}'
...
The function is invoked at oauth.py:1556 (new-user OAuth signup) and oauth.py:1536 (existing-user picture update on login). Neither call site re-validates after redirect-following.
backend/open_webui/retrieval/web/utils.py (v0.9.5) imports the env constant AIOHTTP_CLIENT_ALLOW_REDIRECTS at line 51 and uses it on the five paths patched by CVE-2026-45401. utils/oauth.py does not import or reference it.
Exploitation
Preconditions:
- ENABLE_OAUTH_SIGNUP=true or OAUTH_UPDATE_PICTURE_ON_LOGIN=true (common in production OAuth-IdP deployments)
- Attacker has a valid identity on the configured OAuth IdP (Google, Microsoft, GitHub, or any generic OIDC provider)
Steps:
- Attacker hosts a redirect endpoint at
http://attacker.example/ron a public IP.validate_url("http://attacker.example/r")returns True (is_global=Truefor public IPs). - Attacker sets their IdP
pictureclaim tohttp://attacker.example/r. - Attacker signs in to open-webui via OAuth. open-webui invokes
_process_picture_url("http://attacker.example/r", ...). validate_urlaccepts the public URL.session.get("http://attacker.example/r")is invoked.- attacker.example responds
HTTP/1.1 302 Found\r\nLocation: http://127.0.0.1:11434/api/tags. (Orhttp://169.254.169.254/latest/meta-data/iam/security-credentials/, RFC1918 internal services, etc.) - aiohttp follows the redirect server-side. No re-validation.
- The internal response body is read into
picture, base64-encoded, and stored asprofile_image_url = "data:image/jpeg;base64,..."on the attacker's account. - Attacker reads back via
GET /api/v1/auths/. Decode the base64 payload to get the full internal response body.
Impact
Full-read SSRF, identical read-back primitive to CVE-2026-45338:
- Cloud metadata services (AWS IMDSv1 at
169.254.169.254, GCPmetadata.google.internal, Azure IMDS) → IAM credentials, managed-identity tokens - Localhost-bound services (Ollama at
:11434, Redis, Elasticsearch, internal Postgres exporters) - RFC1918 internal infrastructure not exposed to the internet
Distinction from prior CVEs
| Prior CVE | This finding | Distinguishing fact |
|---|---|---|
| CVE-2026-45338 (GHSA-24c9) | _process_picture_url had no validate_url() call at all |
Fixed in v0.9.0 by adding the call. Ours is the call being insufficient because it doesn't loop over redirect targets. Different mechanism, different fix. |
| CVE-2026-45400 (GHSA-8w7q) | validate_url() had urlparse-vs-requests parser disagreement on \@ chars |
Fixed in v0.9.5 by char-blocklist. Ours is post-validation redirect-following — orthogonal mechanism. |
| CVE-2026-45401 (GHSA-rh5x) | Five paths in retrieval, routers/images, utils/files, utils/middleware | Parent class. Same CWE-918 redirect-bypass mechanism. utils/oauth.py::_process_picture_url is not among the five paths in the parent advisory's "Affected code paths" section. Same class, missed sink. Direct sibling. |
Suggested fix
async with session.get(
picture_url,
**get_kwargs,
ssl=AIOHTTP_CLIENT_SESSION_SSL,
allow_redirects=AIOHTTP_CLIENT_ALLOW_REDIRECTS, # add
) as resp:
Or, if redirects must remain enabled by default, wrap in a manual-follow loop that re-invokes validate_url() on each Location header. This mirrors the fix shape applied to the five paths in CVE-2026-45401.
Affected versions
Vulnerable: <= 0.9.5
Fix: 0.9.6

- CVE-2026-45401 / GHSA-rh5x-h6pp-cjj6 (parent cluster, redirect-bypass on 5 paths)
- CVE-2026-45338 / GHSA-24c9-2m8q-qhmh (original

validate_urlparser-disagreement bypass, patched v0.9.5) - open-webui issue #24560 (corroborates that the v0.9.5 redirect-fix was applied piecemeal across call sites)
Proof of Concept
End-to-end PoC executed against ghcr.io/open-webui/open-webui:v0.9.5 in Docker compose. Three services: attacker (OIDC IdP + 302-redirect endpoint on evil.example.com:9001/redirect), canary (internal target on internal-target.local:9002/sentinel), open-webui v0.9.5.
Fresh-CSPRNG sentinel generated after OAuth state-establishing call (per Gate 5.5 oracle protocol): SSRF-POC-5580111b2a0d7d0c8324bfa92a0d9d09.
Result:
- profile_image_url field after OAuth login: data:image/jpeg;base64,U1NSRi1QT0MtNTU4MDExMWIyYTBkN2QwYzgzMjRiZmE5MmEwZDlkMDk=
- Base64 decode: SSRF-POC-5580111b2a0d7d0c8324bfa92a0d9d09 (byte-for-byte sentinel match)
- Canary log: !!! SSRF HIT - sentinel served
Chain confirmed: OAuth login → IdP returns picture claim evil.example.com:9001/redirect → validate_url() accepts FQDN → aiohttp.ClientSession.get(...) follows 302 to internal-target.local:9002/sentinel server-side without re-validation → response body base64-encoded into attacker's profile_image_url → readable via GET /api/v1/auths/.
PoC artifacts (compose, attacker server, canary, run/verify scripts, full transcript) available on request.

GHSA-22RM-WP4X-V5CX
Vulnerability from github – Published: 2026-03-26 09:30 – Updated: 2026-07-15 20:11A flaw was found in Keycloak. An authenticated attacker can perform Server-Side Request Forgery (SSRF) by manipulating the client_session_host parameter during refresh token requests. This occurs when a Keycloak client is configured to use the backchannel.logout.url with the application.session.host placeholder. Successful exploitation allows the attacker to make HTTP requests from the Keycloak server’s network context, potentially probing internal networks or internal APIs, leading to information disclosure.

The application accepts user-supplied URLs and performs server-side HTTP or HTTPS requests without sufficient validation or destination restrictions. The implementation does not enforce allowlists, block internal or private IP address ranges, or apply request timeouts or response size limits. An attacker can abuse this behavior to induce the server to issue outbound requests to arbitrary hosts, including internal network resources, potentially enabling internal network scanning and denial of service through resource exhaustion.

CAPEC-664: Server Side Request Forgery
An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
