Io.netty:netty handler ssl ocsp: Netty: Out-of-date OCSP Responses Accepted by OcspServerCertificateValidator (CVE-2026-56821)CVE-2026-56821 0 The io.netty netty-handler-ssl-ocsp component's OcspServerCertificateValidator improperly processes out-of-date OCSP responses by flagging them but continuing to treat them as valid. This allows an on-path attacker to replay stale but previously valid OCSP responses, bypassing revocation checks for certificates that have since been revoked. Additionally, nonce validation is off by default, and the freshness check may throw exceptions due to null handling issues.
