NVD analysis in progress

What this means
- Exposure
- Exploitable remotely over the network, with an ordinary user account and with no action from the victim.
- Impact
- An attacker can modify or destroy data. The impact spreads beyond the vulnerable component into other parts of the system.
- 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.
