Vulnerabilidad · Publicado 25/08/2026
El plugin Kalles Addons para WordPress contiene una vulnerabilidad alta de inyección de objetos PHP (CVSS 8.1) en todas las versiones hasta la 1.0.6. Atacantes no autenticados pueden inyectar objetos maliciosos mediante deserialización de entrada no validada. El impacto depende de cadenas POP presentes en otros plugins o temas instalados, siendo de alto riesgo en tiendas WooCommerce y sitios corporativos de LATAM que usen extensiones adicionales.
The Kalles Addons plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.0.6 via deserialization of untrusted input. This makes it possible for unauthenticated attackers 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.
