Advisory Summary

gitlab/packagist/wwbn/avideo/CVE-2026-33292

AVideo has an Authorization Bypass via Path Traversal in HLS Endpoint Allows Streaming Private/Paid Videos The HLS streaming endpoint (`view/hls.php`) is vulnerable to a path traversal attack that allows an unauthenticated attacker to stream any private or paid video on the platform. The `videoDirectory` GET parameter is used in two divergent code paths — one for authorization (which truncates at the first `/` segment) and one for file access (which preserves `..` traversal sequences) — creating a split-oracle condition where authorization is checked against one video while content is served from another.
