CVE-2026-93493: Improper Check for Certificate Revocation in Red Hat Red Hat build of Apache Camel for Spring Boot 4
CVE-2026-93493 is a vulnerability in the Netty component used by the Red Hat build of Apache Camel for Spring Boot 4. It involves improper checking of certificate revocation via OCSP responses that omit the optional nextUpdate field. This omission causes the OCSP validation to be silently skipped, allowing applications to accept unvalidated certificates. This flaw can lead to a bypass of expected certificate validation security controls.
AI Analysis
Technical Summary
The vulnerability exists in Netty's netty-handler-ssl-ocsp component, where an attacker can provide an OCSP response missing the optional nextUpdate field. Because the validation logic does not properly handle this omission, the OCSP check is skipped silently. As a result, applications relying on this component may accept certificates without proper revocation validation, potentially bypassing security mechanisms that depend on certificate trustworthiness. This affects the Red Hat build of Apache Camel for Spring Boot 4, which uses this Netty component.
Potential Impact
The impact is that applications using the affected component may accept revoked or otherwise untrusted certificates due to skipped OCSP validation. This undermines the security guarantees of certificate-based authentication or encryption, potentially allowing attackers to impersonate trusted entities or intercept communications.
