Log disclosure and truncation via tokenless archive request
Published Sep 10, 2026 · Updated Sep 10, 2026
Cross-site request forgery in AVideo through c3edcc274c389816d434acadac07ee78eaf330c1 allows remote attackers to archive application logs. The view/logArchive.json.php endpoint accepts state-changing GET requests without a CSRF token, copies the live log into a publicly reachable ZIP archive, and then truncates the live file. Exploitation requires an authenticated administrator to load attacker-controlled content, exposing sensitive log contents and erasing forensic evidence.
