SPIP before 4.4.5 and 4.3.9 allows an Open Redirect via the login form when used in AJAX mode. An attacker can craft a malicious URL that, when visited by a victim, redirects them to an arbitrary external site after login. This vulnerability only affects sites where the login page has been overridden to function in AJAX mode.

It is not mitigated by the SPIP security screen.
