CVE-2026-3523

Summary

The Apocalypse Meow plugin for WordPress is vulnerable to SQL Injection via the 'type' parameter in all versions up to, and including, 22.1.0. This is due to a flawed logical operator in the type validation check on line 261 of ajax.php — the condition uses && (AND) instead of || (OR), causing the in_array() validation to be short-circuited and never evaluated for any non-empty type value. Combined with stripslashes_deep() being called on line 101 which removes wp_magic_quotes() protection, attacker-controlled single quotes pass through unescaped into the SQL query on line 298. This makes it possible for authenticated attackers, with Administrator-level access and above, to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.
