✅ Remediation

Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 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.
