WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a cross-site request forgery vulnerability in view/logArchive.json.php that allows unauthenticated attackers to archive application logs by making GET requests without CSRF token validation. Attackers can craft malicious pages that trigger administrators' browsers to request the endpoint, copying sensitive application logs to a publicly accessible zip file and truncating the live log to remove forensic evidence.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of WWBN/AVideo published their own advisory on GitHub. Reviewed sources take precedence over it.
