CVE-2026-44566
Open WebUI: Arbitrary File Upload and Path Traversal
Description
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.1.124, when attaching files to a promp, the name of the file is derived from the original HTTP upload request and is not validated or sanitized. This allows for users to upload files with names containing dot-segments in the file path and traverse out of the intended uploads directory. Effectively, users can upload files anywhere on the filesystem the user running the web server has permission. This vulnerability is fixed in 0.1.124.

Action Type Old Value New Value Added Translation Title: Open-webui, Description: Open WebUI es una plataforma de inteligencia artificial autoalojada diseñada para operar completamente sin conexión. Antes de 0.1.124, al adjuntar archivos a un prompt, el nombre del archivo se deriva de la solicitud de carga HTTP original y no se valida ni se sanea. Esto permite a los usuarios cargar archivos con nombres que contienen segmentos de puntos en la ruta del archivo y salir del directorio de cargas previsto. Efectivamente, los usuarios pueden cargar archivos en cualquier lugar del sistema de archivos donde el usuario que ejecuta el servidor web tenga permiso. Esta vulnerabilidad está corregida en 0.1.124. -
