GHSA-v858-922f-fj9v: SimpleSAMLphp Link Injection vulnerability
The following scripts were not checking the URLs obtained via the HTTP request before displaying them as the target of links that the user may click on:
- www/logout.php
- modules/core/www/no_cookie.php The issue allowed attackers to display links targeting a malicious website inside a trusted site running SimpleSAMLphp, due to the lack of security checks involving the link_href and retryURL HTTP parameters, respectively. The issue was resolved by including a verification of the URLs received in the request against a white list of websites specified in the trusted.url.domains configuration option.
