CVE-2025-5396

The Bears Backup plugin for WordPress is vulnerable to Remote Code Execution in all versions up to, and including, 2.0.0. This is due to the bbackup_ajax_handle() function not having a capability check, nor validating user supplied input passed directly to call_user_func(). This makes it possible for unauthenticated attackers to execute code on the server which can be leverage to inject backdoors or create new administrative user accounts to name a few things. On WordPress sites running the Alone theme versions 7.8.4 and older, this can be chained with CVE-2025-5394 to install the Bears Backup plugin and achieve the same impact.

Summary		(es) El complemento Bears Backup para WordPress es vulnerable a la ejecución remota de código en todas las versiones hasta la 2.0.0 incluida. Esto se debe a que la función bbackup_ajax_handle() no realiza una comprobación de capacidad ni valida la entrada proporcionada por el usuario que se pasa directamente a call_user_func(). Esto permite que atacantes no autenticados ejecuten código en el servidor, lo que puede aprovecharse para inyectar puertas traseras o crear nuevas cuentas de usuario administrativas, entre otras cosas. En sitios de WordPress con el tema Alone, versión 7.8.4 o anterior, esto puede combinarse con CVE-2025-5394 para instalar el complemento Bears Backup y obtener el mismo impacto.
