CVE-2026-73780: HPE Arubaos-Cx

High severity, CVSS 8.3. EPSS: 0.2% chance of exploitation in the next 30 days.

A vulnerability in the web-based management interface of AOS-CX switches exposes some sessions to a lack of Cross-Site Request Forgery (CSRF) protection. This could allow a remote unauthenticated attacker to execute arbitrary input against the affected interface if the attacker can convince an authenticated user of the interface to interact with a specially crafted URL.
