# CVE-2026-44873: Insufficient Session Invalidation on User Account Deactivation in AOS-8 Operating System

- Severity: CVSS 5.4 (Medium), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Published: 2026-05-12 · Updated: 2026-05-15

## Affected

- Hewlett Packard Enterprise (HPE) HPE Aruba Networking Wireless Operating System (AOS): from 8.13.0.0, through 8.13.1.1; from 8.12.0.0, through 8.12.0.6; from 8.10.0.0, through 8.10.0.21

## Description

A session management vulnerability in AOS-8 allows previously authenticated users to retain network access after their accounts are administratively disabled. Existing sessions are not invalidated when credentials are revoked, enabling continued access until session expiration. An attacker with compromised credentials could exploit this behavior to maintain unauthorized access even after the account has been disabled.
