CVE-2026-14920Public exploitNetwork attack vector

Unauthenticated database disclosure via raw list IDs

Published Aug 2, 2026 · Updated Aug 2, 2026

SQL injection in AcyMailing before 10.11.1 allows remote attackers to read WordPress database data through the public unsubscribe task. FrontusersController passes subscription[] list IDs unchanged to UserClass::unsubscribe(), which implodes them into a raw numeric SQL IN() clause. Exploitation is unauthenticated but requires a queue row for the attacker's self-registered subscriber; successful blind queries disclose database contents and can delete matching queue data.
