Description
Zipline through 3.7.9 contains an improper authorization vulnerability in the /api/auth/register endpoint, which enforces invite codes only when user registration is disabled, so registration succeeds without an invite when both invites and user registration are enabled. Unauthenticated attackers can send a direct POST request omitting the invite code to create accounts, view stats, and exhaust storage by uploading many files.
