Curl SSL Session ID Cache Ignored OCSP Stapling Check
CVE-2024-0853 Published on February 3, 2024

OCSP verification bypass with TLS session reuse
curl inadvertently kept the SSL session ID for connections in its cache even when the verify status (*OCSP stapling*) test failed. A subsequent transfer to the same hostname could then succeed if the session ID cache was still fresh, which then skipped the verify status check.
