CVE-2026-121455

Summary: DbGate before 7.3.3 Missing Authorization via /connections/test and /connections/save

Details: DbGate before 7.3.3 contains a missing authorization vulnerability that allows connection-restricted authenticated users to bypass LOGIN_PERMISSIONS because test() and save() never call testConnectionPermission. Attackers can submit arbitrary connection definitions to POST /connections/test to probe internal database hosts, or to /connections/save to overwrite stored connections.
