CVE-2020-18660

Name of the Vulnerable Software and Affected Versions: GetSimpleCMS versions 3.3.15 and earlier

Description: The issue is related to an open redirect in the admin/changedata.php file via the redirect function to the url parameter. This allows for potential redirection to unintended locations.

Recommendations: For versions 3.3.15 and earlier, update to a version later than 3.3.15 to resolve the issue. As a temporary workaround, consider restricting access to the admin/changedata.php file or disabling the redirect function to the url parameter until a patch is available.
