What is CVE-2023-34035?

Spring Security versions prior to 5.8.5, 6.0.5, and 6.1.2 contain a vulnerability that may allow for authorization rule misconfigurations. This primarily affects applications that utilize requestMatchers(String) with multiple servlets, including Spring MVC's DispatcherServlet. The application is at risk if it includes Spring MVC on the classpath and secures multiple servlets but does not restrict request matchers to only Spring MVC endpoints. Conversely, applications free of Spring MVC, or that secure only the DispatcherServlet with proper request matchers, are not affected.
