CVE-2021-24345Public exploitNetwork attack vector

Database disclosure via unescaped list identifier

Published Jun 14, 2021 · Updated Aug 3, 2024

Blind SQL injection in Sendit WP Newsletter 2.5.1 and earlier allows remote authenticated users to extract database data via id_lista. In admin-core.php, the lists-management deletion path inserts the id_lista POST value directly into a DELETE statement without sanitization, validation, escaping, or a prepared query. Administrator access to the WordPress dashboard is required, and time-based responses expose queried database values without returning them directly.
