When curl is told to use the Certificate Status Request TLS extension, often referred to as OCSP stapling, to verify that the server certificate is valid, it might fail to detect some OCSP problems and instead wrongly consider the response as fine. If the returned status reports another error than revoked (like for example unauthorized) it is not treated as a bad certficate.
Weakness
The product does not validate, or incorrectly validates, a certificate.
