DescriptionCVE.org

WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 fails to require authentication in the plugin/TopMenu/menus.json.php endpoint, allowing unauthenticated attackers to retrieve all menu data. Attackers can send GET requests to the endpoint to read inactive and admin-only menu names that are not displayed in the public navbar.

AnalysisAI

Unauthenticated information disclosure in WWBN AVideo exposes internal menu configuration data via the plugin/TopMenu/menus.json.php endpoint, which lacks any authentication check. Remote unauthenticated attackers can send a plain GET request to retrieve all menu data, including names of admin-only and inactive menus that are intentionally hidden from the public navbar. …
