✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 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. 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. Workaround: No workaround is available for applications that rely on the Permission Model to restrict process.report.writeReport() output paths. Users should upgrade to a fixed Node.js release (22.23.0, 24.17.0, or 26.3.1 and later) as they become available downstream. Workaround: Limit outbound HTTP/1.1 from Node.js clients to trusted backend endpoints with egress firewall rules or network segmentation. Avoid keep-alive connection pools to untrusted hosts where operationally feasible. Workaround: Restrict Node.js HTTP/2 servers to trusted clients with host firewall or network segmentation. If HTTP/2 is not required, disable the HTTP/2 server API.
