What this means
- Exposure
- Exploitable remotely over the network and without authentication — but only if a user opens booby-trapped content.
- Impact
- An attacker can modify or destroy data. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- Authentication relies on a spoofable value such as an IP address or header.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
