CVE-2026-3523
Apocalypse Meow <= 22.1.0 - Authenticated (Administrator+) SQL Injection via 'type' Parameter
Description
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.
