CVE-2021-38320

Name of the Vulnerable Software and Affected Versions: simpleSAMLphp Authentication WordPress plugin versions up to and including 0.7.0

Description: The issue is related to Reflected Cross-Site Scripting, which occurs due to a reflected $ SERVER["PHP SELF"] value in the ~/simplesamlphp-authentication.php file. This allows attackers to inject arbitrary web scripts.

Recommendations: For versions up to and including 0.7.0, update to a version higher than 0.7.0 to resolve the issue. As a temporary workaround, consider restricting access to the ~/simplesamlphp-authentication.php file to minimize the risk of exploitation.
