Summary
Red Hat Security Advisory: Kiali 1.73.32 for Red Hat OpenShift Service Mesh 2.6
Severity
Important
Notes
Topic: Kiali 1.73.32 for Red Hat OpenShift Service Mesh 2.6 is now available. Red Hat Product Security has rated this update as having a security impact of Moderate. 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 1.73.32, 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-2026-9277 openshift-service-mesh/kiali-rhel8: shell-quote: Arbitrary code execution via command injection due to unescaped line terminators (OSSM-13906) * CVE-2026-9277 openshift-service-mesh/kiali-ossmc-rhel8: shell-quote: Arbitrary code execution via command injection due to unescaped line terminators (OSSM-13905) 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.

A flaw was found in the shell-quote component. The quote() function did not properly validate object-token inputs, allowing line terminators to pass unescaped into the output. A remote attacker could exploit this vulnerability by providing specially crafted input, which a POSIX shell would interpret as a command separator. This could lead to command injection, enabling the attacker to execute arbitrary code on the system.

CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
