Executive Summary

This vulnerability exists in SPIP versions before 4.4.5 and 4.3.9 and involves an Open Redirect via the login form when it is used in AJAX mode.

An attacker can create a malicious URL that, when a victim clicks on it and logs in, will redirect the victim to an arbitrary external website.

This issue only affects sites where the login page has been customized to operate in AJAX mode and is not prevented by the SPIP security screen.

Impact Analysis

The vulnerability can be exploited to redirect users to malicious external sites after they log in, potentially leading to phishing attacks or exposure to harmful content.

Because the redirect happens after login, users might trust the redirected site more, increasing the risk of credential theft or other social engineering attacks.
