Technical details

A stored cross-site scripting (XSS) vulnerability exists in WWBN AVideo versions up to 29.0. The root cause is the lack of output encoding or sanitization of the 'category_description' field in the Gallery plugin's 'mainAreaCategory.php' view. An attacker with category creation or editing privileges can inject a malicious JavaScript payload into the description field via 'objects/categoryAddNew.json.php'. When a victim (user or administrator) views the affected Gallery or category page, the payload executes in their browser context. This can be used to hijack sessions, steal sensitive information, or perform unauthorized administrative actions. A fix involving 'htmlspecialchars()' or 'HTMLPurifier' is recommended.
