Vulnerability from github – Published: 2026-07-24 16:59 – Updated: 2026-07-24 16:59

Summary
Open WebUI: Unauthenticated WebSocket Access to Collaborative Document Handlers (ydoc:awareness:update, ydoc:document:leave)
Details

Summary

The Socket.IO server is configured with always_connect=True (lines 78, 91 in backend/open_webui/socket/main.py) and the connect handler (line 329) never rejects unauthenticated connections. Two Ydoc event handlers have zero authentication checks, allowing unauthenticated clients to interact with collaborative document sessions.

Vulnerable Code

ydoc:awareness:update (line 741) — No auth check at all

@sio.on('ydoc:awareness:update')
async def yjs_awareness_update(sid, data):
    document_id = data['document_id']
    user_id = data.get('user_id', sid)
    update = data['update']
    # No SESSION_POOL check, no room membership check
    await sio.emit(
        'ydoc:awareness:update',
        {'document_id': document_id, 'user_id': user_id, 'update': update},
        room=f'doc_{document_id}',
        skip_sid=sid,
    )

ydoc:document:leave (line 711) — No auth check at all

@sio.on('ydoc:document:leave')
async def yjs_document_leave(sid, data):
    document_id = data['document_id']
    user_id = data.get('user_id', sid)
    # No auth check
    await YDOC_MANAGER.remove_user(document_id=document_id, user_id=sid)
    await sio.emit('ydoc:user:left',
        {'document_id': document_id, 'user_id': user_id},
        room=f'doc_{document_id}')

Root Cause: always_connect=True (line 78)

sio = socketio.AsyncServer(
    always_connect=True,   # Never rejects connections
    ...
)

The connect handler (line 329) adds authenticated users to SESSION_POOL but never returns False or raises an exception for unauthenticated connections.

Exploitation

  1. An unauthenticated attacker connects via Socket.IO (no token needed)
  2. The attacker emits ydoc:awareness:update with:
  3. document_id: a known/guessed note UUID (format: note:{uuid})
  4. user_id: spoofed to impersonate any user
  5. update: arbitrary awareness data (fake cursor positions, selections)
  6. The fake awareness data is broadcast to all legitimate users in the document room
  7. The attacker can also emit ydoc:document:leave with spoofed user_id to broadcast fake ydoc:user:left events

Impact

  • UI disruption: Fake cursor positions and user presence in collaborative editing sessions
  • User impersonation: Attacker can spoof any user_id in awareness updates
  • Resource exhaustion: Unlimited unauthenticated WebSocket connections maintained by the server

Note: Other Ydoc handlers (ydoc:document:join, ydoc:document:update, ydoc:document:state) correctly check SESSION_POOL membership.

Suggested Fix

  1. Set always_connect=False or reject unauthenticated connections in the connect handler
  2. Add SESSION_POOL checks to ydoc:awareness:update and ydoc:document:leave
  3. Add room membership verification before broadcasting to document rooms

AI Disclosure (per Rule 11): AI (Claude) was used to assist with source code review, identifying potential vulnerability patterns, and drafting this report. The researcher directed the analysis, selected focus areas, and independently verified all findings against a running v0.8.12 Docker instance using real HTTP requests with two test accounts. The PoCs included are reproducible and were confirmed live before submission.

Mitigation
Architecture and Design
  • Divide the software into anonymous, normal, privileged, and administrative areas. Identify which of these areas require a proven user identity, and use a centralized authentication capability.
  • Identify all potential communication channels, or other means of interaction with the software, to ensure that all channels are appropriately protected, including those channels that are assumed to be accessible only by authorized parties. Developers sometimes perform authentication at the primary channel, but open up a secondary channel that is assumed to be private. For example, a login mechanism may be listening on one network port, but after successful authentication, it may open up a second port where it waits for the connection, but avoids authentication because it assumes that only the authenticated party will connect to the port.
  • In general, if the software or protocol allows a single session or user state to persist across multiple connections or channels, authentication and appropriate credential management need to be used throughout.
Mitigation MIT-15
Architecture and Design

For any security checks that are performed on the client side, ensure that these checks are duplicated on the server side, in order to avoid CWE-602. Attackers can bypass the client-side checks by modifying values after the checks have been performed, or by changing the client to remove the client-side checks entirely. Then, these modified values would be submitted to the server.

Mitigation
Architecture and Design
  • Where possible, avoid implementing custom, "grow-your-own" authentication routines and consider using authentication capabilities as provided by the surrounding framework, operating system, or environment. These capabilities may avoid common weaknesses that are unique to authentication; support automatic auditing and tracking; and make it easier to provide a clear separation between authentication tasks and authorization tasks.
  • In environments such as the World Wide Web, the line between authentication and authorization is sometimes blurred. If custom authentication routines are required instead of those provided by the server, then these routines must be applied to every single page, since these pages could be requested directly.
Mitigation MIT-4.5
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 libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator [REF-45].
Mitigation
Implementation System Configuration Operation

When storing data in the cloud (e.g., S3 buckets, Azure blobs, Google Cloud Storage, etc.), use the provider's controls to require strong authentication for users who should be allowed to access the data [REF-1297] [REF-1298] [REF-1302].

CAPEC-12: Choosing Message Identifier

This pattern of attack is defined by the selection of messages distributed via multicast or public information channels that are intended for another client by determining the parameter value assigned to that client. This attack allows the adversary to gain access to potentially privileged information, and to possibly perpetrate other attacks through the distribution means by impersonation. If the channel/message being manipulated is an input rather than output mechanism for the system, (such as a command bus), this style of attack could be used to change the adversary's identifier to more a privileged one.

CAPEC-166: Force the System to Reset Values

An attacker forces the target into a previous state in order to leverage potential weaknesses in the target dependent upon a prior configuration or state-dependent factors. Even in cases where an attacker may not be able to directly control the configuration of the targeted application, they may be able to reset the configuration to a prior state since many applications implement reset functions.

CAPEC-216: Communication Channel Manipulation

An adversary manipulates a setting or parameter on communications channel in order to compromise its security. This can result in information exposure, insertion/removal of information from the communications stream, and/or potentially system compromise.

CAPEC-36: Using Unpublished Interfaces or Functionality

An adversary searches for and invokes interfaces or functionality that the target system designers did not intend to be publicly available. If interfaces fail to authenticate requests, the attacker may be able to invoke functionality they are not authorized for.

CAPEC-62: Cross Site Request Forgery

An attacker crafts malicious web links and distributes them (via web pages, email, etc.), typically in a targeted manner, hoping to induce users to click on the link and execute the malicious action against some third-party application. If successful, the action embedded in the malicious link will be processed and accepted by the targeted application with the users' privilege level. This type of attack leverages the persistence and implicit trust placed in user session cookies by many web applications today. In such an architecture, once the user authenticates to an application and a session cookie is created on the user's system, all following transactions for that session are authenticated using that cookie including potential actions initiated by an attacker and simply "riding" the existing session cookie.
