CVE-2023-20862 Information

Description

In Spring Security versions 5.7.x prior to 5.7.8 versions 5.8.x prior to 5.8.3 and versions 6.0.x prior to 6.0.3 the logout support does not properly clean the security context if using serialized versions. Additionally it is not possible to explicitly save an empty security context to the HttpSessionSecurityContextRepository. This vulnerability can keep users authenticated even after they performed logout. Users of affected versions should apply the following mitigation. 5.7.x users should upgrade to 5.7.8. 5.8.x users should upgrade to 5.8.3. 6.0.x users should upgrade to 6.0.3.
