CVE-2024-0853
OCSP verification bypass with TLS session reuse
Medium5.3EPSS 1.1%

- Reserved
- Assigned by
- curl
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.
