About this tag
The mikrotik routeros tag collects coverage of security issues affecting MikroTik RouterOS and Cloud Hosted Router deployments. Recent discussions examine a RouterOS API session-management flaw that can leave previous permissions active after account downgrades or inactivity timeouts, creating risks for access revocation and role changes.
