Summary
WWBN AVideo before 29.5.0 contains a local file inclusion flaw (CWE-22) in setLanguage() that lets unauthenticated attackers include PHP files outside the locale directory through a crafted Accept-Language header. Overlapping traversal sequences such as ....// survive single-pass removal, so an attacker can execute existing server-side PHP files in the application context. Exploitation requires local access, no privileges and no user interaction.
