CVE-2025-4840Public exploitNetwork attack vector

Database disclosure via unsanitized AJAX post parameter

Published Jun 10, 2025 · Updated Jun 10, 2025

SQL injection in erumfaham Likes and Dislikes Plugin 1.0.0 and earlier allows remote attackers to read database data via AJAX. The unauthenticated my_likes_dislikes_action handler places the post parameter into an SQL statement without sanitization or escaping, and crafted expressions can trigger database delays. No account or user interaction is required; successful exploitation exposes data accessible to the WordPress database connection.
