gonic versions before 0.22.0 fail to validate administrator privileges in the startScan endpoint, allowing any authenticated user to trigger media library rescans.
MEDIUM 5.3EPSS 0.27%
Does this matter?
Lower severity and a low EPSS score (0.27%). Track it; it rarely justifies an emergency change on its own.
Description
gonic versions before 0.22.0 fail to validate administrator privileges in the startScan endpoint, allowing any authenticated user to trigger media library rescans. Attackers can repeatedly call the startScan endpoint to force CPU and I/O-intensive filesystem operations, causing denial of service on multi-user instances.
