Mitigation checklist
- To mitigate this issue, Node.js applications should be designed to explicitly configure unique HTTPS agents for each distinct target host. Alternatively, applications can avoid TLS session caching when making outbound HTTPS requests to varied third-party endpoints using shared client instances. Implementing these application-level changes will prevent the vulnerable behavior of skipping hostname verification. Applications may require a restart to apply these changes.
