Key points
- HPE firmware versions up to 8.13.3.0 and 8.10.0.23 are affected by CVE-2026-79850.
- The National Vulnerability Database rates the flaw as critical with a CVSS score of 10.
- No vendor description, exploit details, or confirmed fix has been released yet.
Hewlett Packard Enterprise firmware versions up to 8.13.3.0 and up to 8.10.0.23 are affected by a newly recorded vulnerability, according to the National Vulnerability Database. The issue is identified as CVE-2026-79850. As of now, no security update or patch has been confirmed by the vendor to address this specific gap.
In plain English
The National Vulnerability Database has assigned a CVSS score of 10 to this issue, categorizing it as critical. However, the database entry provides no technical description of the flaw. There is no information about how the vulnerability works or what it allows an attacker to do. Without a vendor statement, the exact nature of the risk remains unknown.
The background
This record lacks the usual context found in security advisories. Unlike previous updates covered by Patch Herald, such as the LibreOffice integer overflow fix reported on 2026-10-16 or the TuxGuitar patch for malicious files on the same date, this entry offers no clarity. Those incidents had clear descriptions and fixes. This one does not.
What changes now
Administrators must verify which firmware versions are running in their environment. The affected versions are explicitly listed as up to 8.13.3.0 and up to 8.10.0.23. If these versions are present, the systems are considered vulnerable according to the NVD record. Until HPE releases a description or a fix, exposure cannot be reduced through software updates.
Who needs to act first
Teams should prioritize identifying systems running the affected firmware versions listed in the advisory. Before making any changes, ensure comprehensive backups exist to prevent data loss during potential remediation efforts. Isolate critical infrastructure segments if possible to limit potential lateral movement while investigating. Monitor official vendor channels for updates, but avoid applying unverified third-party patches. Focus on reducing network exposure for these specific devices until official guidance is provided.
Background: Software updates
Software updates use delta compression to minimize data transfer, verify integrity via digital signatures, and employ transactional installs to ensure the system remains bootable even if the process fails midway.

What to do and how to stay safe: Hewlett Packard Enterprise
- Audit your infrastructure to identify any devices running HPE firmware versions 8.13.3.0 or earlier, or 8.10.0.23 or earlier.
- Monitor official HPE security advisories and the National Vulnerability Database for any new descriptions or patch releases.
- Restrict remote access to affected firmware management interfaces to limit potential attack surfaces while no fix is available.
- Review network logs for unusual activity related to firmware management protocols, as a precautionary measure.
