CVE-2026-27136 is a vulnerability in the golang.org/x/net/html package used by Red Hat Advanced Cluster Management for Kubernetes. When arbitrary HTML is parsed and rendered, it can produce an unexpected HTML tree that bypasses sanitization mechanisms, enabling Cross-Site Scripting (XSS) attacks. This flaw can lead to information disclosure or arbitrary code execution in affected applications. The vulnerability requires user interaction and is rated as Important by Red Hat with a CVSS v3 base score of 8.1. The Red Hat advisory provides updated container images in version 2.13.10 that address this and other security issues. The update is recommended to mitigate these risks.
