CVE-2026-73776
HIGH 7.9A signature verification bypass vulnerability exists in the command line interface of AOS-CX. Successful exploitation could allow an authenticated malicious actor with administrative privileges to execute arbitrary code on the underlying operating system, when certain pre-conditions outside of the attacker’s control are met.
Severe if exploited (CVSS 7.9), but no known exploitation and low modeled probability. Patch on a normal cadence.
