Detailsinfo

A vulnerability classified as critical was found in open-webui Open WebUI up to 0.6.9. This vulnerability affects an unknown part of the component Audio File Handler. The manipulation with an unknown input leads to a path traversal vulnerability. The CWE definition for the vulnerability is CWE-22. The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. As an impact it is known to affect integrity, and availability. CVE summarizes:

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.

The advisory is shared for download at github.com. This vulnerability was named CVE-2026-44565 since 05/06/2026. The exploitation appears to be easy. The attack can be initiated remotely. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1006.
