CVE-2026-73770
HIGH 7.3An authenticated arbitrary file write vulnerability exists in AOS-CX. Successful exploitation could allow an authenticated malicious actor, under specific conditions outside the attacker's control and following a required action by another user, to create or modify arbitrary files and execute arbitrary commands as a privileged user on the underlying operating system.
Severe if exploited (CVSS 7.3), but no known exploitation and low modeled probability. Patch on a normal cadence.
