✅ Remediation
For Red Hat Lightspeed in Satellite installation see the Red Hat Satellite documentation. Workaround: There is no practical mitigation for this vulnerability. The brace-expansion package is typically a transitive dependency pulled in via minimatch and glob, making it difficult to isolate. Users should upgrade to a fixed version of brace-expansion when one becomes available. 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.
