Published

AVideo through 29.0 contains a blind server-side request forgery vulnerability in the getHeaderContentTypeFromURL function that issues get_headers() calls guarded only by format validation. Authenticated users with canUpload permission can store attacker-chosen URLs as video links, triggering vulnerable function execution on every video watch page render to probe internal hosts using content-type oracles and timing-based detection.
