Summary

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.

Affected Version(s)

Spring Security Spring Security 5.8.0 to 5.8.4, Spring Security 6.0.0 to 6.0.4, Spring Security 6.1.0 to 6.1.1

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
