This vulnerability is reported in versions prior to 7.0.27 and 6.0.35. 2) An error within the FormAuthenticator component when handling authentication requests can be exploited to bypass the authentication mechanism via a specially crafted request. This vulnerability is reported in versions prior to 7.0.29 and 6.0.35. 3) An error within the "doFilter()" method when accessing protected resources can be exploited to bypass the CSRF prevention filter and access the resource without a session identifier.
