CVE-2026-43881Public exploitNetwork attack vector

Unauthenticated user enumeration via authorization bypass

Published May 11, 2026 · Updated May 11, 2026

Missing authentication in AVideo 29.0 and earlier allows remote attackers to enumerate registered accounts through a JSON endpoint. The objects/users.json.php handler lets isCompany force $ignoreAdmin to true and accepts users_id without a permission check, bypassing guarded user-list methods. An unauthenticated GET can disclose account IDs, display names, channel URLs, profile images, status values, and the total account count.
