DescriptionCVE.org

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.

AnalysisAI

SQL injection in the Apocalypse Meow WordPress plugin up to version 22.1.0 allows authenticated administrators to execute arbitrary SQL queries due to a flawed validation check combined with improper quote escaping. An authenticated attacker with administrator privileges can exploit this via the 'type' parameter to extract sensitive database information. No patch is currently available.
