The Download Manager Pro plugin for WordPress suffers from a stored XSS vulnerability (CWE-79) due to improper neutralization of input during web page generation. Specifically, the vulnerability exists in the handling of wpdm_user_dashboard, wpdm_package, wpdm_packages, wpdm_search_result, and wpdm_tag shortcodes, where user-supplied attributes are not properly sanitized or escaped. Authenticated attackers with contributor-level privileges or higher can exploit this to inject arbitrary JavaScript that executes in the context of other users viewing the affected pages. This can lead to information disclosure or session hijacking. The vulnerability affects all plugin versions up to and including 3.2.92. There is no indication of known exploits in the wild or an official patch at this time.

Successful exploitation allows an authenticated user with contributor-level access or higher to inject persistent malicious scripts into pages generated by the plugin's shortcodes. These scripts execute in the browsers of users who visit the infected pages, potentially leading to theft of sensitive information or session tokens. The vulnerability does not impact availability but can compromise confidentiality and integrity of user sessions and data within the affected WordPress environment.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or limiting use of the affected shortcodes. Monitor for plugin updates from codename065 and apply them promptly once available.
