AI Analysis
Technical Summary
The vulnerability in LibreTranslate through version 1.9.6 is due to the absence of the access_check decorator on the download_file route. This security control omission enables attackers to bypass authentication mechanisms such as API key checks and ban lists, thereby allowing unauthorized download of translated files from protected instances.
Potential Impact
Attackers can access translated files without authentication, potentially exposing sensitive translated content. However, the impact is limited to confidentiality as integrity and availability are not affected according to the CVSS vector.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the download_file route through other means such as network controls or reverse proxies to prevent unauthenticated access.
