✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ Workaround: Do not pass untrusted or user-controlled input to brace-expansion's expand() function or to libraries that use it for glob pattern matching (such as minimatch or glob). Validate and sanitize any brace patterns before expansion. Where possible, upgrade to brace-expansion 1.1.17, 2.1.3, 3.0.3, or 5.0.8 which add a maxLength option that bounds accumulated output. As an additional defense-in-depth measure, enforce memory limits on Node.js processes using operating system resource controls such as cgroups or Kubernetes resource limits (spec.containers[].resources.limits.memory) to prevent a single process from exhausting system memory and causing a wider outage. Workaround: Applications utilizing undici should implement an independent request deadline and ensure the response body is explicitly destroyed upon expiration. The bodyTimeout mechanism alone is insufficient to prevent resource exhaustion in this scenario. Workaround: To mitigate this vulnerability, do not pass untrusted input to the expand() function. 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.
