CVE-2026-33479 (opens in a new tab)How to fix?
Upgrade wwbn/avideo to version 29.0 or higher.
Overview
wwbn/avideo is an Audio and Video Platform or simply "A Video Platform".
Affected versions of this package are vulnerable to Arbitrary Code Injection via the saveSort.json.php endpoint. An attacker can execute arbitrary PHP code on the server by luring an authenticated admin to visit a malicious page, which triggers a cross-site request that injects unsanitized input into an eval() call.
Note: This is only exploitable if the admin is authenticated and visits an attacker-controlled page while the application is configured with session cookies set to SameSite=None over HTTPS.
Workaround
This vulnerability can be mitigated by replacing the use of eval() with an allowlist check for valid section names and implementing CSRF protection or setting session cookies to SameSite=Lax.
