Netty versions 4.2.0.Final through 4.2.15.Final and versions prior to 4.1.136.Final contain a vulnerability in the OCSP client implementation where the CertificateID in an OCSP response is not validated against the requested certificate's CertificateID. This flaw allows an attacker to replay a valid OCSP response for a different certificate issued by the same CA, bypassing revocation checks and causing the client to accept revoked certificates as valid. The vulnerability has a CVSS score of 9.1, indicating high severity.
