Detailsinfo

A vulnerability was found in WWBN AVideo up to 26.0. It has been rated as critical. This issue affects the function eval of the file saveSort.json.php of the component Session Cookie Handler. The manipulation of the argument sections with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2026-33479 since 03/20/2026. The exploitation is known to be easy. The attack may be initiated remotely. No form of authentication is needed for a successful exploitation. It demands that the victim is doing some kind of user interaction. Technical details are known, but no exploit is available.
