Overview
Affected versions of this package are vulnerable to Insufficient Session Expiration due to the POST /ui/hosts process not honoring configured enrollment token TTL settings and instead issuing tokens with a fixed 24-hour validity. An attacker can obtain enrollment tokens with a longer-than-intended validity period by creating hosts through the Web UI, increasing the risk that exposed or intercepted tokens can be used to enroll unauthorized hosts and retrieve sensitive configuration data.
