The Download Manager WordPress plugin before 3.2.44 does not escape a generated URL before outputting it back in an attribute of the history dashboard, leading to Reflected Cross-Site Scripting
The Download Manager Plugin for WordPress is vulnerable to reflected Cross-Site Scripting in versions up to, and including 3.2.42. This is due to insufficient input sanitization and output escaping on the 'frameid' parameter found in the ~/src/Package/views/shortcode-iframe.php file.
