Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Backup endpoints repeatedly lacked permission checks on storage, pools, and VM config extraction, allowing unauthorized backup operations and data access.
Auth Bypass: Ceph API endpoints had missing or duplicate permission keys, and MDS keyring caps were overly broad, enabling unauthorized cluster management and privilege escalation.
Auth Bypass: Pool-related permission checks used Pool.Allocate instead of Pool.Audit, and pool operations lacked checks entirely, allowing unauthorized access to pool information and modifications.
