What this means
- Exposure

- Impact
- An attacker can take the service offline.
- Weakness
- Access control is applied incorrectly, leaving a protected resource reachable without the required rights.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
