Summary

A vulnerability in Seahub before version 13.0.23 allows unauthenticated users to bypass the SHARE_LINK_LOGIN_REQUIRED enforcement on the GET /api/v2.1/share-link-zip-task/ endpoint.

Recommendation

Upgrade Seahub to version 13.0.23 or later immediately, which enforces authentication for this endpoint.
