CVE-2026-44565
HighSummary
Open WebUI is a self-hosted artificial intelligence platform that prior to version 0.6.10 did not validate or sanitize file names when uploading audio files. This allows users to upload files with names containing dot-segments, enabling traversal out of the intended uploads directory.
Risk Assessment
This vulnerability allows users to upload files anywhere on the filesystem where the web server user has permission, potentially leading to unauthorized access to sensitive data or execution of malicious code.
Recommendation
It is recommended to upgrade to version 0.6.10 or later to mitigate this vulnerability and implement additional security measures to validate and sanitize file names.
Original NVD description (English source)
Open WebUI is a self-hosted artificial intelligence platform designed to operate entirely offline. Prior to 0.6.10, when uploading an audio file, 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 0.6.10.
