What is CVE-2026-33352?

CVE-2026-33352 is a critical SQL injection vulnerability in Wwbn Avideo, published on 23 Mar 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

WWBN AVideo is an open source video platform. Prior to version 26.0, an unauthenticated SQL injection vulnerability exists in `objects/category.php` in the `getAllCategories()` method. The `doNotShowCats` request parameter is sanitized only by stripping single-quote characters (`str_replace("'", '', ...)`), but this is trivially bypassed using a backslash escape technique to shift SQL string boundaries. The parameter is not covered by any of the application's global input filters in `objects/security.php`. Version 26.0 contains a patch for the issue.

Weakness: CWE-89
