Title
Seahub < 13.0.23 - Authentication Bypass in ShareLinkZipTaskView GET Method
Summary
Seahub before 13.0.23 does not enforce SHARE_LINK_LOGIN_REQUIRED on GET /api/v2.1/share-link-zip-task/, allowing unauthenticated users to bypass authentication. Attackers with a folder share-link token can call the GET endpoint to obtain a fileserver zip token and download entire shared directory trees.
