CVE-2025-47916

Invision Community 5.0.0 before 5.0.7 allows remote code execution via crafted template strings to themeeditor.php. The issue lies within the themeeditor controller (file: /applications/core/modules/front/system/themeeditor.php), where a protected method named customCss can be invoked by unauthenticated users. This method passes the value of the content parameter to the Theme::makeProcessFunction() method; hence it is evaluated by the template engine. Accordingly, this can be exploited by unauthenticated attackers to inject and execute arbitrary PHP code by providing crafted template strings.

Summary		(es) Invision Community 5.0.0 anterior a 5.0.7 permite la ejecución remota de código mediante cadenas de plantillas manipuladas en themeeditor.php. El problema reside en el controlador themeeditor (archivo: /applications/core/modules/front/system/themeeditor.php), donde usuarios no autenticados pueden invocar un método protegido llamado customCss. Este método pasa el valor del parámetro content al método Theme::makeProcessFunction(); por lo tanto, lo evalúa el motor de plantillas. Por lo tanto, atacantes no autenticados pueden aprovechar esto para inyectar y ejecutar código PHP arbitrario mediante cadenas de plantillas manipuladas.
