CVE-2026-33292Public exploitNetwork attack vector

Unauthenticated video disclosure via HLS path traversal

Published Mar 22, 2026 · Updated Mar 22, 2026

Path traversal in the HLS endpoint in World Wide Broadcast Network AVideo before 26.0 allows remote attackers to stream restricted videos. The view/hls.php endpoint authorizes only the first segment of videoDirectory, while getPathToFile preserves parent-directory sequences when resolving the file path. An instance needs at least one public video for the pivot; the flaw exposes private, unlisted, group-restricted, or paid HLS content without granting modification or service interruption.
