CVE-2026-33479 Details
Description
WWBN AVideo is an open source video platform. In versions up to and including 26.0, the Gallery plugin's `saveSort.json.php` endpoint passes unsanitized user input from `$_REQUEST['sections']` array values directly into PHP's `eval()` function. While the endpoint is gated behind `User::isAdmin()`, it has no CSRF token validation. Combined with AVideo's explicit `SameSite=None` session cookie configuration, an attacker can exploit this via cross-site request forgery to achieve unauthenticated remote code execution — requiring only that an admin visits an attacker-controlled page. Commit 087dab8841f8bdb54be184105ef19b47c5698fcb contains a patch.
A vulnerability in the WWBN AVideo Gallery plugin, affecting versions through 26.0, allows for cross-site request forgery (CSRF) attacks that can lead to unauthenticated remote code execution. The issue arises in the 'saveSort.json.php' endpoint, which directly passes unsanitized user input from the 'sections' array into PHP's 'eval()' function. Although the endpoint requires admin privileges, it lacks proper CSRF token validation. This vulnerability is exacerbated by AVideo's 'SameSite=None' session cookie policy, enabling attackers to exploit the flaw if they can lure an admin into visiting a malicious page.
Users can update to the patched version of the AVideo Gallery plugin, which is available on the official GitHub repository. The latest version includes the necessary input validation and CSRF protection. For those who cannot update immediately, consider disabling the Gallery plugin or implementing manual CSRF protections.
