CVE-2026-76730
An authentication bypass vulnerability exists in the PAPI protocol of HPE Networking Instant ON APs that could allow an unauthenticated adjacent attacker to circumvent existing authentication controls.
Does this matter?
Lower severity and a low EPSS score (0.21%). Track it; it rarely justifies an emergency change on its own.
