Technical Summary
This advisory covers Kiali 2.4.16 for Red Hat OpenShift Service Mesh 3.0, which fixes eight security vulnerabilities: CVE-2026-32280 (Go denial of service in certificate chain building), CVE-2026-40895 (information disclosure via cross-domain redirects in follow-redirects), and six Axios-related prototype pollution vulnerabilities (CVE-2026-42033, CVE-2026-42035, CVE-2026-42039, CVE-2026-42041, CVE-2026-42043, CVE-2026-42044) that enable HTTP transport hijacking, arbitrary header injection, denial of service, authentication bypass, NO_PROXY bypass, and invisible JSON response tampering. These vulnerabilities collectively impact the security and integrity of HTTP communications and error handling within Kiali's service mesh observability functions. The advisory does not provide CVSS scores but rates the overall impact as critical.
Potential Impact
The vulnerabilities fixed in Kiali 2.4.16 can lead to denial of service conditions, information disclosure, HTTP transport hijacking, arbitrary HTTP header injection, authentication bypass, and tampering with JSON responses. These issues compromise the confidentiality, integrity, and availability of the service mesh observability component, potentially allowing attackers to disrupt service monitoring, bypass security controls, or leak sensitive information.
Mitigation Recommendations
Red Hat has released Kiali version 2.4.16 for OpenShift Service Mesh 3.0 that addresses these vulnerabilities. Users should upgrade to this version to mitigate the risks. No other temporary mitigations or workarounds are specified. Patch status is confirmed by the vendor advisory. Refer to Red Hat's official documentation and advisory RHSA-2026:16534 for upgrade instructions.
