GHSA-2P48-J3QC-RX9F rclone: S3 multipart declared-length memory exhaustion

Summary In streamed multipart mode, serve s3 passes the request's declared part length to multipart.NewRW.ReservecontentLength before reading any part data. Reserve immediately obtains enough 1 MiB pool pages for the entire declared length. The request handler therefore allocates attacker-selecte...

GHSA-3G9Q-V48F-HH9W Open WebUI: Unauthenticated requests can stall the server via uncached OIDC fetches in back-channel logout

Summary The OIDC back-channel logout endpoint is unauthenticated by design, because the identity provider calls it without a browser session. Before checking whether the submitted logout token was genuine, the handler fetched the provider's discovery document and its signing keys over the network...

GHSA-V39V-59XW-J98G Open WebUI: Any authenticated user can suppress calendar alerts instance-wide via a non-numeric alert value

Any authenticated user can suppress calendar alerts instance-wide via a non-numeric alert value Summary Calendar events carry a free-form meta object that is stored exactly as submitted, with no validation of the values inside it. The scheduler reads the per-event alert offset out of that object ...

GHSA-8R35-5X5R-HV74 Open WebUI: Any authenticated user can start a non-terminating request via a folder parent cycle

Summary Any authenticated user can move one of their own folders under itself, leaving a loop in their folder tree. The re-parent endpoint performed no check that the new parent was not the folder itself or one of its own subfolders, and the folder tree walks did not track which folders they had...

GHSA-WJWR-XFP9-R66P Open WebUI: Admin demoted through SSO role sync keeps read and write access to all users' notes

Summary A user who is demoted from admin by an identity provider keeps admin-level read and write access to every user's notes, over any Socket.IO connection that was already open when the demotion happened. Open WebUI caches the user's role on the socket at connection time, and the two SSO...

GHSA-M3WP-48JR-VR4G mistral.rs: Unbounded Remote Media Fetch and Video Frame Expansion DoS

Unbounded Remote Media Fetch and Video Frame Expansion DoS Summary The POST /v1/chat/completions endpoint in mistral.rs fetches attacker-supplied media URLs image, audio, video into server memory with no byte limit, and extracts every frame of a supplied video when numframes is None. An...

GHSA-WFGQ-W7CQ-QJ7J mistral.rs Media Loader: Unauthenticated SSRF and arbitrary local file read via image_url

Summary mistral.rs fetches any request-supplied image/audio URL with no host or IP validation, and opens arbitrary local files a file:// URL, or any existing relative/absolute path. A remote, unauthenticated client of any vision/audio deployment can cause the server to issue requests to internal ...

GHSA-P78M-89R6-PGF7 Open WebUI: A user's session cookies are sent to tool servers configured for bearer authentication

Summary When more than one external tool server is reachable in the same request, a tool call to a server configured for bearer authentication can arrive carrying the calling user's Open WebUI session cookies alongside that server's own key. The cookie jar is built per connection, but the callabl...

GHSA-WPMR-8H3Q-FWJ7 Open WebUI: Sign-in as another user via wildcard characters in the OAuth subject claim on SQLite

Summary On SQLite deployments, the lookup that maps an external identity to a local account does a substring match instead of an exact match. A subject value containing SQL wildcard characters therefore matches accounts the value was never issued for, and the sign-in binds to whichever account th...

GHSA-HF57-CQMX-P4GR OmniRoute ACP Custom-Agent Remote Code Execution (RCE)

Summary POST /api/acp/agents registers a custom ACP agent. The endpoint accepts user-controlled binary and versionCommand values. After saving the custom agent, the same request calls refreshAgentCache, which triggers agent version detection. The version probe eventually runs: ts...

GHSA-CW9W-VV67-HF73 n8n: Per-Resource OAuth Consent Bypass via Unbound Refresh Token Resource Substitution

Impact The OAuth token endpoint bound an authorization code's first access token to the consented resource, but not its refresh token. Refreshing only checked that the requested resource was registered, not that it matched the original grant. An OAuth client approved for one workflow could refres...

GHSA-Q5WM-MGQX-FV2F n8n: Instance AI Credential Setup Accepts Unvalidated Probe URL from Fetched Content

Impact Instance AI credential setup accepted a credential test/verification URL without checking it matched the workflow node's origin. Exfiltration required the user to actively inject an attacker-controlled URL into the setup flow. The patch derives the credential destination from the node's ow...

GHSA-QGPW-8G46-W95V n8n: Git Node branch.<name>.remote Config Key Bypasses Sandbox Path Restriction, Enabling Local Git Repository Read

Impact The Git node validated the repository that a fetch or pull targeted, but setUpstream wrote a branch..remote value into the repository's own configuration without validating it. A subsequent fetch or pull resolved the remote from that configuration rather than from the checked parameter, so...

GHSA-CQR2-H44G-V75V n8n: Cross-Tenant Project-Member PII Disclosure via Missing Per-Project Scope Check on Role Assignment Endpoints

Impact The endpoints /rest/roles/:slug/assignments and /rest/roles/:slug/assignments/:projectId/members checked only that the caller could manage the role type, not that they could see the project named in the request. A user holding role-management permission could therefore name any project on...

GHSA-PQ6C-VH67-XPM3 n8n: Log Streaming Event Destinations Decrypt Generic-Auth Credentials Without Ownership Check

Impact A log streaming event destination may reference a generic HTTP credential, and the destination resolved and decrypted whichever credential it named without checking that the caller had access to it. A user holding a custom global role scoped to Log Streaming operations could therefore name...

GHSA-PF83-W3F9-8M37 n8n: Disabled OIDC SSO Endpoints Remain Active and Issue Valid Sessions

Impact The public OIDC login and callback endpoints ran the full flow whether or not OIDC was the instance's active, enabled authentication method, so turning OIDC off in Settings did not stop it issuing sessions. An administrator who disabled the provider still had a working login route. The pat...

GHSA-5M98-CGCR-XX3Q n8n: GitHub Trigger 422 Reuse Path Skips Webhook Secret Storage, Causing Signature Verification to Fail-Open

Impact The GitHub Trigger generated a signing secret when it registered a webhook and verified X-Hub-Signature-256 on each delivery. When GitHub answered the create request with a 422 because a webhook for the URL already existed, the node adopted the remote hook but kept only its id and events,...

GHSA-F2CP-M7MV-8JPV n8n: Path Injection in Elasticsearch and ElasticSecurity Nodes via Unencoded Identifiers

Impact The Elasticsearch and ElasticSecurity nodes built REST endpoints by interpolating user-provided identifiers straight into the request path. A value containing path separators or dot segments changed which endpoint the request actually reached, so an operation intended for one document coul...

GHSA-679F-58PQ-4V2C n8n: Prototype Pollution via Workflow Structure Summary Can Lead to Denial of Service

Impact The Instance AI workflow summary built its result with get-or-create-then-nested-write idioms keyed by node names and connection keys taken from the stored workflow. Those are arbitrary strings: the restricted-name guard n8n shows in the editor is client-side and is bypassed by posting the...

GHSA-65XW-2V52-JHXC n8n: Cross-User Active Workflow ID and Lifecycle Event Disclosure via Missing userId Filter

Impact The endpoint /rest/active-workflows returned every active workflow ID on the instance to any member, regardless of sharing, and workflow activation, deactivation and publication push events were broadcast to every connected client, carrying workflow IDs, version IDs and activation-error...

GHSA-6XCW-7XM6-48C6 n8n: Expression Sandbox Escape via Shared Builtin Tampering and Code-Printer Injection Leads to Code Execution

Impact Two stages of expression code generation built source text by calling the global JSON.stringify at generation time: the compiler when printing synthetic string literals, and the isolate bridge when interpolating a timezone value into its per-evaluation wrapper. An expression that replaced...

GHSA-35JJ-42HP-8GMQ n8n: Anonymous Approval-Gate Bypass via Reused resumeToken over the Chat WebSocket

Impact The /chat WebSocket route resumed a paused execution from a resume token without checking that the node being resumed was a chat node. n8n hands that token to anonymous form submitters, so a party with no account could present it on the chat route and release an execution waiting at an...

GHSA-RF44-J88R-HH8C Traefik: ForwardAuth identity spoofing via dot-form header alias

Summary There is a medium severity vulnerability in Traefik's handling of request headers whose name aliases another header name. Go canonicalizes header names on dashes only, so X-Auth-User, XAuthUser and X.Auth.User are three distinct headers to Traefik, while backends that derive variable name...

GHSA-7GHQ-V6JF-G56C Traefik: respondingTimeouts.readTimeout is not applied to HTTP/3, leaving slow-body uploads unbounded

Summary There is a medium severity vulnerability in Traefik's HTTP/3 entry points: the respondingTimeouts settings were not applied to the HTTP/3 request path. readTimeout in particular is on by default at 60s and is documented as bounding the time to read the entire request including its body, b...

GHSA-34FF-336R-5Q23 n8n: Domain-Restriction Bypass via Unguarded Model-Search Endpoint in OpenAI Chat Model Node

Impact The OpenAI Chat Model node checked a custom base URL against the credential's allowed-domains configuration before sending a request, but the model-search dropdown did not. A request setting options.baseURL on that path reached an arbitrary host with the credential attached, so the domain...

GHSA-J535-V25Q-VX3Q n8n: Regular Expression Denial of Service in the Default Blocked-File-Pattern Match via a Git Node Clone Path

Impact The Git node's clone operation matched the destination path against the default N8NBLOCKFILEPATTERNS expression, which was written so that a crafted path caused catastrophic backtracking. Evaluation runs synchronously in the main n8n process, so an authenticated user could freeze the...

GHSA-HH89-3R9W-QJ3J n8n: Unauthenticated Persistent Storage Exhaustion via OAuth Dynamic Client Registration Endpoint

Impact The OAuth Dynamic Client Registration endpoints validated field sizes only for redirecturis, leaving clientname and granttypes bounded by presence checks alone. An unauthenticated remote caller could submit arbitrarily large values in either field and have them persisted to the database...

GHSA-HW8V-XXG5-VVVX n8n: Expression Sandbox Escape via Class-Field Sanitizer Rebinding Can Lead to Code Execution

Impact The expression compiler's sanitizer resolved through a dynamically-scoped this, so a class field named sanitize rebound it and reached the Function constructor. On the backend, any expression author could run code in the n8n process; in the editor preview, a member's expression could run a...

GHSA-PCVC-8VRV-8Q6W Open WebUI: Inaccessible knowledge bases are exposed through the built-in knowledge tool on most vector backends

Summary The built-in knowledge search tool returns knowledge bases the calling user has no access to. The tool works out which knowledge bases the caller may read and hands that set to the vector store as a search filter, and that filter is the only access control on the path. Most of the shipped...

GHSA-FMQH-XP37-5HR8 Open WebUI: Channel members can overwrite another member's message via the chat completions endpoint

Summary Any member of a channel who can post to it could also replace the text of a message written by a different member. The channel branch of the chat completions endpoint checked that the caller may write to the channel, and that the targeted message belongs to that channel, but never checked...

GHSA-JMC6-2WR8-H3WJ Open WebUI: Same-origin XSS to account takeover via terminal port-preview iframe hardcoding allow-same-origin

Summary Any authenticated user with access to a shared terminal server could get script of their choosing to run in the Open WebUI origin itself. The in-app port preview rendered the content of a previewed port in an iframe whose sandbox always granted allow-same-origin alongside allow-scripts, a...

GHSA-4V28-J6Q3-5M4R Open WebUI: SSRF into internal services via DNS rebinding in the Playwright web loader

Summary With the Playwright web loader enabled, Open WebUI checks the address behind a user-submitted URL before allowing the request, then handed the request to the browser to perform. The browser resolved the hostname a second time, on its own, and that answer was never checked. An attacker who...

GHSA-3PF7-Q2G3-WJ28 Open WebUI: Any authenticated user can inject chats into another user's folder via chat completions

Summary The chat-completions endpoint reads a folder id out of the request body and saves the newly created chat into that folder without checking that the caller is allowed to write there. Any authenticated user who knows a folder's id can put a chat of their own into another user's folder,...

GHSA-2724-6CPJ-GF3V Open WebUI: Non-admin users can delete admin-owned external knowledge connections via knowledge base deletion

Summary External knowledge connections are created and owned by administrators, and are shared by every external knowledge base bound to them. Deleting an external knowledge base also removed that connection from the instance configuration, with no check on the caller's role and no check for othe...

GHSA-34R3-9M95-VQ73 Open WebUI: Any authenticated user can reach the Azure platform channel via server-side web fetch

Summary Open WebUI fetches user-supplied URLs on the server for RAG URL ingestion and web search, and screens the resolved addresses so internal destinations cannot be reached. That screen decided whether a destination was external by asking Python's standard library whether the address is global...

GHSA-4QG5-CXX4-G927 Open WebUI: Users denied by the OAuth domain allowlist or role policy can still sign in via token exchange

Summary Open WebUI's OAuth token exchange endpoint issues a session for a provider access token without applying the email domain allowlist that the normal OAuth login callback enforces. An account whose email domain the login callback would refuse could still obtain a working session through thi...
