- Mitigation guidance
- To mitigate this prevent connection reuse (CURLOPT_FORBID_REUSE) for transfers using Negotiate authentication with empty credentials and strictly isolate libcurl connection pools across different security principals. For defense-in-depth, enforce network boundaries to limit outbound HTTP access, mitigating the impact of any potential cross-session data exposure while pending upstream patches.
