SSL bundle configuration silently bypassed in Spring Cloud Gateway
When configuring SSL bundles in Spring Cloud Gateway by using the configuration property spring.ssl.bundle, the configuration was silently ignored and the default SSL configuration was used instead. 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/ . Ideally if you are not an enterprise customer, you should be upgrading to 5.0.2 or 5.1.1 which are the current supported open source releases.

Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
