CVE-2026-92803 Details
Description
LibreTranslate through 1.9.6 omits the access_check decorator from the download_file route, allowing unauthenticated access to translated files. Attackers can bypass API key requirements and abuse ban lists to download files without authentication on protected instances.
A vulnerability exists in LibreTranslate versions through 1.9.6, where the download_file route lacks the necessary access_check decorator. This omission allows unauthenticated users to access translated files, bypassing API key requirements and exploiting ban lists to download files from protected instances. The vulnerability arises because the download_file route does not enforce the same access controls as other content-serving routes, leaving a gap that can be exploited by attackers.
Users can update to LibreTranslate version 1.9.7 or later, where this vulnerability has been addressed.
