Description

The vulnerability allows a remote attacker to redirect users to an attacker-controlled site.

The vulnerability exists due to url redirection to an untrusted site in src/Saml/Security/SamlAuthenticationSuccessHandler.php when processing the RelayState parameter in the SAML ACS handler. A remote attacker can supply a malicious RelayState value to redirect users to an attacker-controlled site.

SAML must be enabled, and exploitation is limited to IdP-initiated SSO flows where a malicious RelayState value is included. User interaction is required to complete SAML authentication.
