Severity
Important
Notes
Topic: Kiali 1.73.27 for Red Hat OpenShift Service Mesh 2.6
This update has a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details: Kiali 1.73.27, 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):
* kiali-ossmc-rhel8: Axios affected by Denial of Service via __proto__ Key in mergeConfig (CVE-2026-25639)
* kiali-rhel8: Axios affected by Denial of Service via __proto__ Key in mergeConfig (CVE-2026-25639)
* kiali-rhel8: golang: Denial of Service due to excessive resource consumption via crafted certificate (CVE-2025-61729)

A flaw was found in golang. A remote attacker could exploit this vulnerability by providing a specially crafted certificate during the error string construction process within the `HostnameError.Error()` function. This flaw, caused by unbounded string concatenation, leads to excessive resource consumption. Successful exploitation can result in a denial of service (DoS) for the affected system.
7.5 (High)
Vendor Fix
See Kiali 1.73.27 documentation at https://docs.redhat.com/en/documentation/openshift_container_platform/4.18/html/service_mesh/service-mesh-2-x
https://access.redhat.com/errata/RHSA-2026:3107
A denial of service flaw has been discovered in the Axios npm package. the mergeConfig function in axios crashes with a TypeError when processing configuration objects containing __proto__ as an own property. An attacker can trigger this by providing a malicious configuration object created via JSON.parse(), causing complete denial of service.
7.5 (High)
Vendor Fix
See Kiali 1.73.27 documentation at https://docs.redhat.com/en/documentation/openshift_container_platform/4.18/html/service_mesh/service-mesh-2-x
https://access.redhat.com/errata/RHSA-2026:3107
Workaround
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
