CVE-2026-6251Network attack vector

Authenticated SQL injection via raw widget identifier

Published Jul 28, 2026 · Updated Jul 28, 2026

Time-based blind SQL injection in Premio Chaty Pro 3.5.5 and earlier allows remote authenticated users to read database contents. The fetch_custom_field() function in admin/class-admin-base.php concatenates the POST widget_id value into a numeric SQL query before checking the nonce, without preparation or integer casting. Subscriber-level access is sufficient, and the time-based query oracle permits database reads rather than direct writes or service interruption.
