CVE-2026-82600Public exploitNetwork attack vectorHinoki check available

Unauthenticated database query manipulation via numeric expressions

Published Aug 31, 2026 · Updated Aug 31, 2026

SQL injection in the zyapi.php video API in SeaCMS 13.0 through 13.6 allows remote attackers to manipulate database queries via ids. The videolist handler applies addslashes() to ids, then concatenates the result inside an SQL IN clause without enforcing a comma-separated integer list. The public endpoint requires no authentication, but the demonstrated exploit only changes numeric query expressions; the application's SQL guard restricts common UNION, subquery, and file-write payloads.
