| Doc Text: |
A flaw was found in Spring Security. This vulnerability allows a remote attacker to impersonate another user. The SubjectX500PrincipalExtractor component incorrectly handles certain malformed X.509 certificate Common Name (CN) values, which can lead to the system reading an incorrect username. By presenting a carefully crafted certificate, an attacker can exploit this to gain unauthorized access.
