CVE-2026-73780Network attack vector

Arbitrary management input via missing CSRF protection

Published Sep 1, 2026 · Updated Sep 3, 2026

CSRF in the AOS-CX web management interface allows remote attackers to submit arbitrary input through certificate-authenticated sessions. The interface omits CSRF protection for some certificate-authenticated sessions, so a crafted URL sends attacker-chosen input with the victim's authority. Exploitation requires an authenticated user to interact with that URL, and resulting actions are bounded by the session's interface privileges.
