What is CVE-2023-20862?

In Spring Security, certain versions exhibit a flaw in the logout process that fails to effectively clear the security context when utilizing serialized versions. This issue can result in users remaining authenticated even after they attempt to log out. Specifically, it prevents the explicit saving of an empty security context, potentially allowing unauthorized access. Users are advised to upgrade to the appropriate patched versions—5.7.8 for 5.7.x, 5.8.3 for 5.8.x, and 6.0.3 for 6.0.x—to mitigate this vulnerability.
