Red Hat Security Advisory: Kiali 2.4.20 for Red Hat OpenShift Service Mesh 3.0
Kiali 2.4.20, for Red Hat OpenShift Service Mesh 3.0, provides observability for the service mesh by offering a visual representation of the mesh topology and metrics, helping users monitor, trace, and manage efficiently. Security Fix(es): * CVE-2026-42264 openshift-service-mesh/kiali-ossmc-rhel9: Axios: Prototype pollution allows information disclosure and request manipulation (OSSM-14588) * CVE-2026-42264 openshift-service-mesh/kiali-rhel9: Axios: Prototype pollution allows information disclosure and request manipulation (OSSM-14593) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
AI Analysis
Technical Summary
The vulnerability CVE-2026-42264 affects Axios, used in Kiali 2.22.7 for Red Hat OpenShift Service Mesh 3.3. It is a prototype pollution flaw where an attacker can inject malicious properties into the JavaScript Object.prototype. If another component in the same environment is compromised and pollutes the prototype, Axios may unknowingly incorporate these manipulated properties into its outbound HTTP requests. This behavior can result in sensitive information disclosure and network request manipulation. Exploitation requires a prior successful prototype pollution attack on a co-located dependency. Red Hat has released a patch to fix this vulnerability.
Potential Impact
The vulnerability can lead to disclosure of sensitive information and manipulation of network requests by exploiting prototype pollution in Axios. This compromises the confidentiality and integrity of data handled by the affected software. Exploitation depends on a prior successful prototype pollution attack from another component in the same environment. There are no known exploits in the wild at this time.
Mitigation Recommendations
A patch is available and should be applied to affected versions of Kiali in Red Hat OpenShift Service Mesh. Red Hat recommends upgrading to Kiali 2.4.20 or later, which includes the fix for CVE-2026-42264. No alternative mitigations meeting Red Hat's criteria are currently available. Users should follow Red Hat's official guidance and update their deployments accordingly.
