CVE-2026-54423
Authenticated users can send arbitrary IPMI commands via Ironic, bypassing access controls
Is CVE-2026-54423 being exploited?
Not confirmed. CVE-2026-54423 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 0.30% probability of exploitation in the next 30 days.
How severe is CVE-2026-54423?
CVE-2026-54423 is rated High. 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-2026-54423?
Yes. A fix has been recorded for CVE-2026-54423. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.

Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Authenticated deployers can execute arbitrary IPMI commands on nodes, enabling power control, firmware/OS tampering, or full system compromise.

As published in the CVE Program record. A version outside these ranges is not a statement that it is unaffected — vendors sometimes understate a range, and distribution-backported builds carry upstream numbers that do not reflect what was patched into them.
