CVE-2026-88873
HIGH 7.1 ALL-YEARSWWBN 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.
Severe if exploited (CVSS 7.1), but no confirmed exploitation. Patch on a normal cadence.
