CVE-2026-27732Network attack vector

Authenticated internal-data access via unrestricted downloadURL fetch

Published Feb 24, 2026 · Updated Feb 24, 2026

SSRF in WWBN AVideo before 22.0 allows remote authenticated users to retrieve sensitive data through server-side URL requests. The aVideoEncoder.json.php endpoint passes its downloadURL parameter to url_get_contents without first restricting the destination. A low-privilege account can make the server contact arbitrary internal endpoints, exposing returned internal API or metadata-service data.
