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.
