Documentation

An application is vulnerable to Session Fixation attacks when .sessionFixation() is set to .none(). Spring Security's default setting is migrateSession() which will -upon creation of a new HTTP session- invalidate the old one, and copy its attributes to the new session. Another option is to use newSession() which will create a brand new session without any attributes from the old one, and invalidate the latter.

Before
httpSecurity.sessionManagement().sessionFixation().none();
After
httpSecurity.sessionManagement().sessionFixation().newSession();
