✅ Remediation

For details on how to apply this update, which includes the changes described in this advisory, refer to: https://images.redhat.com/ 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: To reduce exposure, restrict the processing of untrusted YAML documents by applications that rely on `js-yaml`. Implement robust input validation and sanitization for all YAML data originating from external or untrusted sources. Consider limiting network access to services that parse YAML content to trusted networks or clients through appropriate firewall configurations.
