✅ Remediation
For Red Hat Lightspeed in Satellite installation see the Red Hat Satellite documentation. 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. 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. Until updates are available, restrict the processing of user-supplied URIs to trusted sources only, implement strict allowlists for destination hosts (preferably IP-based rather than hostname-based), and apply egress filtering to prevent server-initiated connections to internal networks or cloud metadata services. Workaround: There is no mitigation available for this issue. Apply updates as they become available from Red Hat product teams.
