HPE ClearPass Policy Manager: Authentication bypass in web and API interfaces
Summary
Authentication bypass vulnerabilities in the web management and API interfaces of HPE Networking ClearPass Policy Manager allow an unauthenticated remote attacker to circumvent authentication controls. Successful exploitation grants administrative access to the affected system. ClearPass controls network access, so a compromise could expose user credentials, device data and network policies. The CVSS base score is 9.8 (critical).
Affected
- HPE ClearPass Policy Manager 6.14.0
- HPE ClearPass Policy Manager 6.11.0 through 6.11.15

Fixed in
- Upgrade to 6.14.1 or later
- Upgrade to 6.11.16 or later
(Per Tenable and Secure-iss. Confirm in HPE bulletin HPESBNW05158.)
Workaround

Our recommendation
- Patch ClearPass Policy Manager to 6.14.1 or 6.11.16 (or later) as soon as possible.
- Until patched, restrict access to the web UI and API to a dedicated management network or jump host, and check whether the interface is reachable from the internet.
- Monitor administrative logins for unexpected activity.
- Also review related CVEs in the same HPE bulletin, such as CVE-2026-76750 and CVE-2026-79796.
