🛡️ CVE-2026-3523
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.
How this vulnerability can be exploited
This issue can be reached over the network, attack complexity is low, an attacker needs administrative privileges on the target. No user interaction is required. The scope is unchanged, so the impact stays within the vulnerable component. Rated impact: confidentiality high, integrity none, availability none.
Weakness class
CVE-2026-3523 is classified as CWE-89: SQL Injection. Untrusted input is concatenated into an SQL statement, letting an attacker change the query and reach data the request should not return.
