Red Hat Security Advisory: Kiali 1.73.30 for Red Hat OpenShift Service Mesh 2.6
Kiali 1.73.30, for Red Hat OpenShift Service Mesh 2.6, 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-2026-32280 Go: Denial of Service vulnerability in certificate chain building (OSSM-13521) * CVE-2026-40895 follow-redirects: Information disclosure via cross-domain redirects (OSSM-13550, OSSM-13551) * CVE-2026-41240 DOMPurify: Cross-Site Scripting (XSS) via inconsistent tag sanitization (OSSM-13592) * CVE-2026-42033 Axios: HTTP Transport Hijacking via Prototype Pollution (OSSM-13687, OSSM-13688) * CVE-2026-42035 Axios: Arbitrary HTTP header injection via prototype pollution (OSSM-13594, OSSM-13595) * CVE-2026-42039 Axios: Denial of Service via unbounded recursion in toFormData with deeply nested request data (OSSM-13725, OSSM-13726) * CVE-2026-42041 Axios: Authentication bypass due to prototype pollution of HTTP error handling (OSSM-13739, OSSM-13740) * CVE-2026-42043 Axios: NO_PROXY bypass via crafted URL (OSSM-13711, OSSM-13712) Enhancement(s): * OSSM-12301 Migration from Yarn Classic (v1) to Yarn v4 or NPM 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
Kiali 1.73.30 for Red Hat OpenShift Service Mesh 2.6 includes security fixes for several vulnerabilities: CVE-2026-32280 is a denial of service vulnerability in Go's crypto/x509 and crypto/tls packages caused by uncontrolled resource consumption when processing excessive intermediate certificates during certificate chain building. Other fixed issues include information disclosure via cross-domain redirects (CVE-2026-40895), cross-site scripting via inconsistent tag sanitization in DOMPurify (CVE-2026-41240), and multiple prototype pollution vulnerabilities in Axios leading to HTTP transport hijacking, arbitrary HTTP header injection, denial of service, and authentication bypass (CVE-2026-42033, CVE-2026-42035, CVE-2026-42039, CVE-2026-42041, CVE-2026-42043). Red Hat rates the overall security impact as critical and provides updated container images and documentation for remediation.
Potential Impact
The vulnerabilities fixed in this release can lead to denial of service conditions, information disclosure, cross-site scripting attacks, HTTP transport hijacking, arbitrary HTTP header injection, and authentication bypass. The most critical impact is the denial of service caused by resource exhaustion in the Go certificate chain building process. These issues could make the affected system or application unavailable or expose sensitive information if exploited. However, there are no known exploits in the wild at this time.
Mitigation Recommendations
A fix is available in Kiali version 1.73.30 for Red Hat OpenShift Service Mesh 2.6. Users should upgrade to this version to address the listed vulnerabilities. Refer to the official Red Hat advisory and Kiali 1.73.30 documentation for detailed upgrade instructions. No additional mitigations are specified by the vendor beyond applying the update.
