CVE-2026-34362

WWBN AVideo is an open source video platform. In versions up to and including 26.0, the verifyTokenSocket() function in plugin/YPTSocket/functions.php has its token timeout validation commented out, causing WebSocket tokens to never expire despite being generated with a 12-hour timeout. This allows captured or legitimately obtained tokens to provide permanent WebSocket access, even after user accounts are deleted, banned, or demoted from admin. Admin tokens grant access to real-time connection data for all online users including IP addresses, browser info, and page locations. Commit 5d5237121bf82c24e9e0fdd5bc1699f1157783c5 fixes the issue.

Summary

The verifyTokenSocket() function in plugin/YPTSocket/functions.php has its token timeout validation commented out, causing WebSocket tokens to never expire despite being generated with a 12-hour timeout. This allows captured or legitimately obtained tokens to provide permanent WebSocket access, even after user accounts are deleted, banned, or demoted from admin. Admin tokens grant access to real-time connection data for all online users including IP addresses, browser info, and page locations.

Details

WebSocket tokens are generated via getEncryptedInfo() which calls getToken(43200) to create a token with a 12-hour expiration window. The token is encrypted and contains security-critical claims: isAdmin, from_users_id, user_name, IP, browser, and device ID.

The regular HTTP token verification at objects/functions.php:3437-3439 enforces the timeout:

// objects/functions.php:3437-3439
if (!($time >= $obj->time && $time <= $obj->timeout)) {
    _error_log("verifyToken token timout...");
    return false;  // <-- enforced
}

But the WebSocket-specific verification at plugin/YPTSocket/functions.php:65-82 has the enforcement commented out:

// plugin/YPTSocket/functions.php:77-80
if (!($time >= $obj->time && $time <= $obj->timeout)) {
    //_error_log("verifyToken token timout...");
    //return false;  // <-- NOT enforced, always falls through to return true
}
return true;

Execution flow:

1. Client connects to WebSocket with ?webSocketToken=TOKEN in URL query
2. onOpen() (Message.php:34) calls getDecryptedInfo($wsocketGetVars['webSocketToken']) (line 48)
3. getDecryptedInfo() (functions.php:49) decrypts the token and calls verifyTokenSocket($json->token) (line 54)
4. verifyTokenSocket() validates the salt (passes) but the timeout check at line 77 evaluates the condition without acting on failure — return false is commented out
5. Function returns true — connection established with all token claims (isAdmin, from_users_id) trusted

Impact amplification via isAdmin:

When a connection has isAdmin=true (from token, Message.php:58), the getTotals() function (Message.php:419-432) includes detailed data about every connected client in periodic broadcast messages:

// Message.php:419-432
if ($isAdmin) {
    $index = md5($client['selfURI']);
    // Exposes: selfURI, yptDeviceId, users_id, user_name, browser, ip, location
    $return['users_uri'][$index][$client['yptDeviceId']][$client['users_id']] = $client;
}

Additionally, the webSocketToken message type (Message.php:212-217) allows anonymous connections (users_id=0) to upgrade their identity by providing a captured token, meaning stolen tokens work from new connections indefinitely.

The 10-minute inactivity timeout (Message.php:135-143) is not a mitigation — it only closes idle connections and resets on every message (line 243).

PoC

# Step 1: Obtain a WebSocket token as any authenticated user
curl -s -b 'PHPSESSID=VALID_SESSION' \
  'https://target.com/plugin/YPTSocket/getWebSocket.json.php' | jq -r '.webSocketToken'
# Save as TOKEN=<output>

# Step 2: Wait for the token to expire (>12 hours)
# In a real scenario, the attacker already has a previously captured token

# Step 3: Connect with the expired token — succeeds because verifyTokenSocket() skips timeout
wscat -c 'ws://target.com:8888/?webSocketToken=TOKEN'

# Step 4: Verify the connection is established and receiving broadcasts
# The server will send periodic getTotals data

# Step 5: If the token was from an admin, the getTotals response includes
# all connected clients' selfURI, IP, browser, device ID, user_name, and location

# Step 6: Any user can also enumerate connected users without admin:
# Send: {"msg":"getClientsList","webSocketToken":"TOKEN"}
# Response includes all users_id, isAdmin status, and usernames

Scenario: Demoted admin retains permanent admin WebSocket access
