Open WebUI allows Remote Code Execution via Arbitrary File Upload to /audio/api/v1/transcriptions

High severity GitHub Reviewed Published Mar 20, 2025 to the GitHub Advisory Database • Updated Mar 21, 2025

Package

pip open-webui (pip)

Affected versions

< 0.5.17

Patched versions

Description

OpenWebUI version 0.3.0 contains a vulnerability in the audio API endpoint /audio/api/v1/transcriptions that allows for arbitrary file upload. The application performs insufficient validation on the file.content_type and allows user-controlled filenames, leading to a path traversal vulnerability. This can be exploited by an authenticated user to overwrite critical files within the Docker container, potentially leading to remote code execution as the root user.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
