CVE-2026-81732Public exploitNetwork attack vectorHinoki check available

Unauthenticated registration-statistics disclosure via unguarded endpoints

Published Aug 28, 2026 · Updated Aug 29, 2026

Information disclosure in WWBN AVideo 30.0 and earlier allows remote attackers to read user-registration counts via unauthenticated GET requests. The report4.json.php and report4.1.json.php endpoints query daily and cumulative registration statistics and return the results without checking for a session or authorization. Any network client that can reach either endpoint can obtain aggregate registration activity, but no individual user records or data-modification capability are reported.
