CVE-2026-22750
Spring Cloud Gateway's SSL bundle configuration silently bypassed

Note: The 4.2.x branch is no longer under open source support. If you are using Spring Cloud Gateway 4.2.0 and are not an enterprise customer, you can upgrade to any Spring Cloud Gateway 4.2.x release newer than 4.2.0 available on Maven Centeral https://repo1.maven.org/maven2/org/springframework/cloud/spring-cloud-gateway/ .
