What is CVE-2026-110216?

Youlai-Boot versions up to 2.21.1 expose a serious vulnerability due to a missing authorization check in the updateUserStatus handler. This flaw allows any authenticated user to send PATCH requests to modify account statuses via the endpoint /api/v1/users/{userId}/status. As a result, attackers can disable critical accounts, including administrator and root accounts, potentially locking out legitimate administrators or re-enabling accounts previously disabled by them.

Affected Version(s)

youlai-boot 0 <= 2.21.1
