Detailsinfo A vulnerability, which was classified as problematic, has been found in codename065 Download Manager Plugin up to 3.3.52 on WordPress. This issue affects an unknown code block of the file members.php of the component Shortcode Handler. The manipulation of the argument sid with an unknown input leads to a cross site scripting vulnerability. Using CWE to declare the problem leads to CWE-79. The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users. Impacted is integrity. The summary by CVE is: The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'sid' parameter of the 'wpdm_members' shortcode in versions up to and including 3.3.52. This is due to insufficient input sanitization and output escaping on the user-supplied 'sid' shortcode attribute. The sid parameter is extracted without sanitization in the members() function and stored via update_post_meta(), then echoed directly into an HTML id attribute in the members.php template without applying esc_attr(). This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses the injected page.
