High CVSS 8.2
CVE-2026-2891
NVD analysis in progress
The following Poly Voice IP devices, CCX, Trio, and Edge E, might be inoperable if they connect to a malicious SIP server and receive malformed data. HP is releasing updates to mitigate these potential vulnerabilities.
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim. It also depends on circumstances the attacker does not control.
- Impact
- An attacker can take the service offline.
- Weakness
- A request that is cheap for the attacker consumes unbounded resources on the server.
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
What to doFold into the next patch cycle. Start with the instances exposed to the internet.
