Vulnerability details
The vulnerability allows a remote user to overwrite translations in target languages outside their permitted language scope.
The vulnerability exists due to incorrect authorization in Tolgee's auto-translate endpoint when permission checks use filtered language tags but translation writes use the original requested tags. A remote user can submit an auto-translate request with useMachineTranslation=true&languages=de while holding project-level translation edit capability but lacking permission for German to overwrite German translations.
