Name of the Vulnerable Software and Affected Versions: Securimage-WP-Fixed WordPress plugin versions up to and including 3.5.4

Description: The issue is related to Reflected Cross-Site Scripting, which occurs due to the use of $ SERVER['PHP SELF'] in the ~/securimage-wp.php file. This allows attackers to inject arbitrary web scripts.

Recommendations: For versions up to and including 3.5.4, update to a version later than 3.5.4 to resolve the issue. As a temporary workaround, consider restricting access to the ~/securimage-wp.php file to minimize the risk of exploitation.
