CVE-2026-84200
Kyverno policy-exception bug allows enforce-mode policy bypass enabling dangerous host mounts.
Is CVE-2026-84200 being exploited?
Not confirmed. CVE-2026-84200 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 0.18% probability of exploitation in the next 30 days.
How severe is CVE-2026-84200?
CVE-2026-84200 is rated Critical with a CVSS score of 9.4. 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-2026-84200?
Yes. A fix has been recorded for CVE-2026-84200. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.
What does CVE-2026-84200 affect?
CVE-2026-84200 affects Kyverno v1.9.0 - v1.12.7, Kubernetes clusters using Kyverno policy engine. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
What should I do about CVE-2026-84200?
Upgrade Kyverno to v1.13.0+, audit hostPath policies, and block risky exceptions.
Exploitation status reflects CISA's KEV catalog as we last synced it. Check the catalog directly.
Attackers can craft resource names to bypass enforce-mode policies (e.g., allow hostPath mounts), enabling container-to-host compromise and potential RCE.

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.
