CVE-2026-93493

DiscoveredSep 18, 2026UpdatedSep 18, 2026

A flaw was found in Netty's netty-handler-ssl-ocsp component. A remote attacker can exploit this vulnerability by providing an Online Certificate Status Protocol (OCSP) response that omits the optional nextUpdate field. This omission causes the OCSP validation to be silently skipped, leading to applications proceeding with an unvalidated certificate. This can result in a bypass of security controls where certificate validation is expected.
