CVE-2024-0853

OCSP verification bypass with TLS session reuse

Published Feb 3, 2024 CVSS 3.1 · 5.3 Medium EPSS 1.1% KEV · Not listed
Description
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.
