CVE-2026-44566 Details
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.
A path traversal vulnerability allowing arbitrary file upload has been identified in Open WebUI versions prior to 0.1.124. When files are attached to a prompt through the web interface, the file names are taken from the original HTTP upload request without any validation or sanitization. This oversight enables users to upload files with names that include dot-segments, allowing them to traverse out of the designated uploads directory. As a result, files can be uploaded to any location on the filesystem where the user running the web server has permissions.
Users are advised to update Open WebUI to version 0.1.124 or later, where this vulnerability has been fixed.
