- Mitigation guidance
- Disable HTTP/2 Server Push (CURLMOPT_PUSHFUNCTION) and shared connection handles (CURL_LOCK_DATA_CONNECT) in libcurl clients to eliminate the vulnerable code path. If these features cannot be disabled, enforce host-based firewalls to restrict affected applications' outbound HTTPS traffic solely to trusted endpoints, neutralizing the risk of exploitation by malicious HTTP/2 servers.
