Code Review

This pull request addresses the Cross-Site Scripting (XSS) vulnerability identified as CVE-2023-36306. The fix involves replacing the vulnerable $_SERVER['PHP_SELF'] superglobal with the safer $_SERVER['SCRIPT_NAME'] in the CreateCurrentUrl() function. This is the correct approach to mitigate this type of XSS attack, as $_SERVER['SCRIPT_NAME'] is not susceptible to path injection. The change is located in a shared function, which ensures the vulnerability is fixed across all the affected components of the application. The patch is correct and effectively resolves the security issue.
