CVE-2026-3352

Status: DeferredHigh (7.2)—

The Easy PHP Settings plugin for WordPress is vulnerable to PHP Code Injection in all versions up to, and including, 1.0.4 via the `update_wp_memory_constants()` method. This is due to insufficient input validation on the `wp_memory_limit` and `wp_max_memory_limit` settings before writing them to `wp-config.php`. The `sanitize_text_field()` function used for sanitization does not filter single quotes, allowing an attacker to break out of the string context in a PHP `define()` statement. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject and execute arbitrary PHP code on the server by modifying `wp-config.php`, which is loaded on every page request.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Esto se debe a una validación de entrada insuficiente en las configuraciones 'wp_memory_limit' y 'wp_max_memory_limit' antes de escribirlas en 'wp-config.php'. La función 'sanitize_text_field()' utilizada para la sanitización no filtra las comillas simples, lo que permite a un atacante salir del contexto de la cadena en una declaración PHP 'define()'. Esto hace posible que atacantes autenticados, con acceso de nivel de Administrador y superior, inyecten y ejecuten código PHP arbitrario en el servidor modificando 'wp-config.php', que se carga en cada solicitud de página."
