The probability is the direct output of the EPSS model, and conveys an overall sense of the threat of exploitation in the wild. The percentile measures the EPSS probability relative to all known EPSS scores. Note: This data is updated daily, relying on the latest available EPSS model version. Check out the EPSS documentation for more details.

Test your applicationsUpgrade org.springframework.security:spring-security-core
to version 5.4.4, 5.3.8.RELEASE, 5.2.9.RELEASE or higher.
org.springframework.security:spring-security-core is a package that provides security services for the Spring IO Platform.
Affected versions of this package are vulnerable to Privilege Escalation. It fails to save the SecurityContext
if it has changed more than once in a single request. The SecurityContext
can fail to save to the HttpSession if a developer changes the SecurityContext twice in a single request when both of the following conditions are met: First the developer must change the SecurityContext before the HttpResponse is committed and then the HttpResponse must be committed before the SecurityContextPersistenceFilter completes. Then the developer must attempt to change the SecurityContext again before the SecurityContextPersistenceFilter completes. A malicious user cannot cause the bug to happen (it must be programmed in). However, if the application's intent is to only allow the user to run with elevated privileges in a small portion of the application, the bug can be leveraged to extend those privileges to the rest of the application.
