CVE-2026-79811 Hewlett Packard Enterprise (HPE) CVE debrief

Who should care

Defenders responsible for ClearPass Policy Manager instances, especially those with internet-exposed administrative interfaces, should assess exposure and prioritize patching. Additionally, vulnerability management teams, security teams, and operators of affected systems should be aware of the potential risks and take necessary precautions to prevent exploitation. This includes restricting administrative access, monitoring for suspicious activity, and rem

Why it matters

CVE-2026-79811 is a high-severity vulnerability in ClearPass Policy Manager API, allowing authenticated SQL injection and remote code execution. Defenders should prioritize patching, restrict administrative access, and monitor for suspicious activity.

• Potential remote code execution requires immediate patching priority
• Authenticated attackers with administrative privileges can exploit the vulnerability
• SQL injection attacks can lead to arbitrary database command execution

Technical summary

The vulnerability is caused by a SQL injection weakness in the ClearPass Policy Manager API, which allows an authenticated attacker with administrative privileges to execute arbitrary database commands. This can lead to remote code execution, making it a high-severity vulnerability. The API's lack of proper input validation enables attackers to inject malicious SQL code, potentially resulting in unauthorized database modifications. Defenders should prioritize patching ClearPass Policy Manager instances, especially those with administrative access exposed to the internet.

Defensive priority

Defenders should prioritize patching ClearPass Policy Manager instances, especially those with administrative access exposed to the internet.

Recommended defensive actions

• Patch ClearPass Policy Manager instances to the latest version
• Restrict administrative access to the API
• Monitor for suspicious database activity
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and source item provide details on the vulnerability, but affected versions and remediation steps require verification from official sources. The ClearPass Policy Manager API is vulnerable to SQL injection attacks, which can lead to remote code execution. Defenders should verify the affected scope, severity, and vendor guidance to ensure proper mitigation. Official sources, such as the CVE Program record and NIST NVD detail page, provide additional information on the vulnerability.
