Vulnerability from github – Published: 2026-07-24 20:49 – Updated: 2026-07-24 20:49
VLAI
Summary
Open WebUI: Terminal proxy forwards a spoofable, integrity-unbound user identity to the upstream (X-User-Id header and ws_terminal session_id query injection)
Details

Summary

The terminal proxy in backend/open_webui/routers/terminals.py forwards the Open WebUI user's identity to the upstream terminal server / backend coordinator as an authorization claim, with no cryptographic binding to the session that produced it. The forwarded identity is attacker-influenceable on both proxy paths:

  1. HTTP path (proxy_terminal) sets headers['X-User-Id'] = user.id. Upstreams that trust X-User-Id as identity receive it unsigned, so an attacker who can reach the upstream by other means (directly, a compromised peer, SSRF) can spoof it.
  2. WebSocket path (ws_terminal) is exploitable through Open WebUI itself, with no "other means" required. It interpolates the path parameter session_id directly into the upstream URL and then appends ?user_id=<caller>:

python upstream_url = f'{ws_base}/p/{policy_id}/api/terminals/{session_id}' upstream_url += f'?{urllib.parse.urlencode({"user_id": user.id})}'

session_id is neither validated nor URL-encoded (the HTTP sibling runs _sanitize_proxy_path; this path runs nothing). An encoded ?/& smuggled through session_id survives Open WebUI's single decode and is re-decoded by the upstream, injecting an attacker-chosen user_id ahead of the appended one. Query parsing binds the first occurrence, so the backend coordinator resolves the spoofed user's terminal scope.

Technical Details

The forwarded terminal identity is a bearer-style authorization claim with no integrity binding, and on the WebSocket path it is additionally injectable because session_id is concatenated into the URL without encoding or delimiter validation.

Impact

A normal authenticated user can make the terminal proxy present another user's identity to the upstream backend coordinator. On backend coordinator-backed (policy_id) servers that scope terminal containers by user_id, this reaches another user's terminal scope; combined with a known active session ID (for example a chat-scoped session ID surfaced through a shared chat), it allows attaching to that user's live PTY. The HTTP-path variant additionally allows identity spoofing at the upstream tier for any deployment whose upstream trusts X-User-Id.

Appendix: Affected code

  • backend/open_webui/routers/terminals.pyproxy_terminal sets headers['X-User-Id'] = user.id with no signature.
  • backend/open_webui/routers/terminals.pyws_terminal builds the upstream URL from an unvalidated, unencoded session_id and appends user_id as a query parameter, allowing query injection.

Appendix: Consolidation

Per the Report Handling policy, this consolidates independent reports of the same root cause (the forwarded terminal identity is spoofable / not integrity-bound) into the earliest filing:

  • @smoke-wolf (earliest filing) — the X-User-Id HTTP-path identity is forwarded without integrity binding, spoofable where the upstream trusts the header.
  • @rexpository — the ws_terminal session_id query-injection vector, proving the forwarded user_id is spoofable through the Open WebUI proxy itself, with no "reach the upstream by other means" precondition.

Appendix: Recommended fix

  • Validate and URL-encode session_id before building the upstream URL (urllib.parse.quote(session_id, safe=""); reject ?, #, &, /, %, backslash, control characters). Build the query string with a URL builder so attacker-controlled path content cannot precede it.
  • Bind the forwarded identity instead of passing a raw user_id / X-User-Id: emit a short-lived signed claim (for example HS256 over {uid, iat, aud:server_id} with a key shared only with the specific upstream) and verify it upstream.

  "details": "## Summary\n\nThe terminal proxy in `backend/open_webui/routers/terminals.py` forwards the Open WebUI user\u0027s identity to the upstream terminal server / backend coordinator as an authorization claim, with no cryptographic binding to the session that produced it. The forwarded identity is attacker-influenceable on both proxy paths:\n\n1. **HTTP path (`proxy_terminal`)** sets `headers[\u0027X-User-Id\u0027] = user.id`. Upstreams that trust `X-User-Id` as identity receive it unsigned, so an attacker who can reach the upstream by other means (directly, a compromised peer, SSRF) can spoof it.\n2. **WebSocket path (`ws_terminal`)** is exploitable through Open WebUI itself, with no \"other means\" required. It interpolates the path parameter `session_id` directly into the upstream URL and then appends `?user_id=\u003ccaller\u003e`:\n\n   ```python\n   upstream_url = f\u0027{ws_base}/p/{policy_id}/api/terminals/{session_id}\u0027\n   upstream_url += f\u0027?{urllib.parse.urlencode({\"user_id\": user.id})}\u0027\n   ```\n\n`session_id` is neither validated nor URL-encoded (the HTTP sibling runs `_sanitize_proxy_path`; this path runs nothing). An encoded `?`/`\u0026` smuggled through `session_id` survives Open WebUI\u0027s single decode and is re-decoded by the upstream, injecting an attacker-chosen `user_id` ahead of the appended one. Query parsing binds the first occurrence, so the backend coordinator resolves the spoofed user\u0027s terminal scope.\n\n## Technical Details\n\nThe forwarded terminal identity is a bearer-style authorization claim with no integrity binding, and on the WebSocket path it is additionally injectable because `session_id` is concatenated into the URL without encoding or delimiter validation.\n\n## Impact\n\nA normal authenticated user can make the terminal proxy present another user\u0027s identity to the upstream backend coordinator. On backend coordinator-backed (`policy_id`) servers that scope terminal containers by `user_id`, this reaches another user\u0027s terminal scope; combined with a known active session ID (for example a chat-scoped session ID surfaced through a shared chat), it allows attaching to that user\u0027s live PTY.

Mitigation
Architecture and Design

Strategy: Libraries or Frameworks

Use an authentication framework or library such as the OWASP ESAPI Authentication feature.

CAPEC-114: Authentication Abuse

An attacker obtains unauthorized access to an application, service or device either through knowledge of the inherent weaknesses of an authentication mechanism, or by exploiting a flaw in the authentication scheme's implementation. In such an attack an authentication mechanism is functioning but a carefully controlled sequence of events causes the mechanism to grant access to the attacker.

CAPEC-115: Authentication Bypass

An attacker gains access to application, service, or device with the privileges of an authorized or privileged user by evading or circumventing an authentication mechanism. The attacker is therefore able to access protected data without authentication ever having taken place.

CAPEC-151: Identity Spoofing

Identity Spoofing refers to the action of assuming (i.e., taking on) the identity of some other entity (human or non-human) and then using that identity to accomplish a goal. An adversary may craft messages that appear to come from a different principle or use stolen / spoofed authentication credentials.

CAPEC-194: Fake the Source of Data

An adversary takes advantage of improper authentication to provide data or services under a falsified identity. The purpose of using the falsified identity may be to prevent traceability of the provided data or to assume the rights granted to another individual. One of the simplest forms of this attack would be the creation of an email message with a modified "From" field in order to appear that the message was sent from someone other than the actual sender. The root of the attack (in this case the email system) fails to properly authenticate the source and this results in the reader incorrectly performing the instructed action. Results of the attack vary depending on the details of the attack, but common results include privilege escalation, obfuscation of other attacks, and data corruption/manipulation.

CAPEC-22: Exploiting Trust in Client

An attack of this type exploits vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by communicating directly with the server where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.

CAPEC-57: Utilizing REST's Trust in the System Resource to Obtain Sensitive Data

This attack utilizes a REST(REpresentational State Transfer)-style applications' trust in the system resources and environment to obtain sensitive data once SSL is terminated.

CAPEC-593: Session Hijacking

This type of attack involves an adversary that exploits weaknesses in an application's use of sessions in performing authentication. The adversary is able to steal or manipulate an active session and use it to gain unathorized access to the application.

CAPEC-633: Token Impersonation

An adversary exploits a weakness in authentication to create an access token (or equivalent) that impersonates a different entity, and then associates a process/thread to that that impersonated token. This action causes a downstream user to make a decision or take action that is based on the assumed identity, and not the response that blocks the adversary.

CAPEC-650: Upload a Web Shell to a Web Server

By exploiting insufficient permissions, it is possible to upload a web shell to a web server in such a way that it can be executed remotely. This shell can have various capabilities, thereby acting as a "gateway" to the underlying web server. The shell might execute at the higher permission level of the web server, providing the ability the execute malicious code at elevated levels.

CAPEC-94: Adversary in the Middle (AiTM)

An adversary targets the communication between two components (typically client and server), in order to alter or obtain data from transactions. A general approach entails the adversary placing themself within the communication channel between the two components.
