Unauthenticated RCE in widely deployed HPE AOS-10 network software; can fully compromise network gear and infrastructure.
CVE-2026-79861
Unauthenticated command injection in AOS-10 allowing privileged RCE.
Is CVE-2026-79861 being exploited?
Not confirmed. CVE-2026-79861 does not appear in CISA's Known Exploited Vulnerabilities catalog, which records only exploitation that has been observed and reported publicly. That is evidence of absence of a report, not evidence the flaw is unattacked. EPSS currently estimates a 1.6% probability of exploitation in the next 30 days.
How severe is CVE-2026-79861?
CVE-2026-79861 is rated Critical with a CVSS score of 9.8. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.
Is there a patch for CVE-2026-79861?
Not known from our data. No patch reference has been recorded for CVE-2026-79861, which is not the same as no patch existing — a fix may have shipped without a tagged reference, or after this record was written. The vendor advisory is the only authority on whether a fix exists, and mitigations may be available regardless.
What does CVE-2026-79861 affect?
