CVE-2026-110253
El plugin weForms – Easy Drag & Drop Contact Form Builder For WordPress para WordPress es vulnerable a una eliminación limitada de archivos multimedia debido a una validación insuficiente de la ruta de archivo en la función weforms_delete_entry_attachments en todas las versiones hasta la 1.6.28 inclusive. Esto permite a atacantes sin autenticar eliminar archivos multimedia arbitrarios del servidor. Para ello es necesario que un administrador elimine de forma permanente la entrada de formulario envenenada, una acción rutinaria de moderación de envíos con aspecto de spam que el atacante puede provocar mediante ingeniería social.
