Vulnerabilidad · Publicado 23/08/2026
El plugin Password Protect Pages (PPWP) para WordPress en versiones hasta 1.9.18 es vulnerable a inyección de objetos PHP mediante deserialización insegura del parámetro 'post_protection_roles'. Atacantes autenticados con acceso de Colaborador o superior pueden ejecutar código arbitrario en servidores web. Esta vulnerabilidad afecta principalmente a sitios corporativos y de comercio electrónico en México y LATAM que protegen contenido sensible con este plugin.
The PPWP – Password Protect Pages plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.9.18 via deserialization of untrusted input from the 'post_protection_roles' vulnerable parameter. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
