Red Hat Security Advisory: Kiali 2.11.12 for Red Hat OpenShift Service Mesh 3.1
Kiali 2.11.12, for Red Hat OpenShift Service Mesh 3.1, 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-2026-32281 redhat-user-workloads/kiali-3-1: Go crypto/x509: Denial of Service via inefficient certificate chain validation (ossm-13868) * CVE-2026-9277 openshift-service-mesh/kiali-ossmc-rhel9: shell-quote: Arbitrary code execution via command injection due to unescaped line terminators (ossm-13909) * CVE-2026-9277 openshift-service-mesh/kiali-rhel9: shell-quote: Arbitrary code execution via command injection due to unescaped line terminators (ossm-13913) 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
This advisory covers security fixes in Kiali 2.11.12 for Red Hat OpenShift Service Mesh 3.1. It includes two main vulnerabilities: CVE-2026-32281, a denial of service in Go's crypto/x509 package caused by inefficient validation of certificate chains with numerous policy mappings, which can lead to resource exhaustion during certificate validation; and CVE-2026-9277, an arbitrary code execution vulnerability due to command injection in the shell-quote package caused by unescaped line terminators. The DoS vulnerability requires an attacker to present a specially crafted but trusted certificate chain, implying the attacker must have compromised a trusted root certificate. Red Hat has rated the overall security impact as moderate and provides Kiali 2.11.12 as the updated version addressing these issues. However, no patch is currently available for the DoS vulnerability in crypto/x509 due to mitigation challenges. The advisory references Red Hat's errata RHSA-2026:26077 and related CVE pages for further details.
Potential Impact
The denial of service vulnerability (CVE-2026-32281) can cause excessive resource consumption during certificate chain validation, potentially degrading or interrupting service availability. Exploitation requires a specially crafted trusted certificate chain, which implies a high attacker capability. The arbitrary code execution vulnerability (CVE-2026-9277) allows an attacker to execute arbitrary commands via command injection in shell-quote due to unescaped line terminators, posing a high risk of system compromise if exploited. Red Hat rates the overall security impact as moderate. There are no known exploits in the wild at this time.
Mitigation Recommendations
Users should upgrade to Kiali version 2.11.12 for Red Hat OpenShift Service Mesh 3.1, which addresses the arbitrary code execution vulnerabilities. For the denial of service vulnerability in Go's crypto/x509 package, no official fix or mitigation currently meets Red Hat's criteria for deployment and stability. Users should monitor Red Hat advisories for future updates. No additional mitigations are specified by Red Hat for these issues at this time.
