SCA: security update for WWBN/AVideo (GHSA-8whc-2wmv-ww35)

critical Tenable Cloud Security Plugin ID 477923

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - WWBN AVideo is an open source video platform. Versions prior to 29.0 contain a stored DOM Cross-Site
 Scripting vulnerability in the YPTSocket plugin. Any unauthenticated remote attacker can execute arbitrary
 JavaScript in the authenticated origin of every administrator currently viewing a page that renders the
 YPTSocket online-users debug panel. plugin/YPTSocket/getWebSocket.json.php issues a signed WebSocket token
 to any anonymous caller, and MessageSQLiteV2::onOpen at plugin/YPTSocket/MessageSQLiteV2.php lines 91 and
 110 reads the attacker-controlled webSocketSelfURI and page_title query parameters from the WebSocket
 connection URL with no validation. Both values persist into the in-memory SQLite connections table and
 broadcast inside the users_id_online array sent to every connected client; on the client,
 plugin/YPTSocket/script.js::updateSocketUserCard interpolates the broadcast page_title into an HTML
 template literal that is passed to jQuery $.append(html), which parses attacker bytes into live DOM nodes
 including <img> with inline event handlers. Successful attackers can can read non-HttpOnly cookies and the
 CSRF token rendered into the admin dashboard, issue authenticated requests to any admin-only endpoint,
 exfiltrate the admin dashboard DOM, and chain into any admin-context mutation. When the victim is an
 AVideo administrator, the attacker turns a single anonymous WebSocket connection into full administrative
 takeover via the admin's own session. This issue has been patched by
 https://github.com/WWBN/AVideo/commit/8be71e53ccbe9b84b30870db386fb4d2b11e1c16. (CVE-2026-54458)

Solution

Update the WWBN/AVideo library and its related packages to version 29.1.0 or later.
