CVE-2026-22750Network attack vector

TLS policy bypass via inverted bundle-name check

Published Apr 10, 2026 · Updated Apr 10, 2026

TLS policy bypass in Spring Cloud Gateway 4.2.0 allows remote attackers to compromise outbound connection integrity through default SSL settings. AbstractSslConfigurer.getBundle() returns null whenever the configured bundle name is nonempty, so the gateway never retrieves the named SslBundle. Exposure requires an application to name an SSL bundle for gateway HTTP client connections; the omitted key and trust material determine the consequence.
