What this means
- Exposure
- Exploitable remotely over the network and without authentication — but only if a user opens booby-trapped content. The attack does require particular conditions, which makes it less systematic.
- Impact
- An attacker can read sensitive data, modify or destroy data and take the service offline.
- Weakness
- Unfiltered input is concatenated into a command, letting the attacker append their own.
- Likelihood
- Its EPSS score puts short-term exploitation in a middle band: neither negligible nor imminent.
