Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check download-manager plugin version
    In WordPress admin, go to Plugins > Installed Plugins and locate 'Download Manager' to see the installed version number. Alternatively, check the main plugin file (typically wp-content/plugins/download-manager/wpdm.php or similar) for the 'Version' header in the plugin comments.
    Affected if The installed version is 3.3.52 or any earlier version.
  2. Identify plugin download endpoints
    Review the plugin's available shortcodes, public pages, and any URLs containing 'download' or 'wpdm' in the site. Common patterns include URLs with 'download.php', 'file', or 'download' parameters.
    Affected if The site has active download links or pages created using the Download Manager plugin.
  3. Test unauthenticated access to download functions
    Attempt to access identified download URLs in a private/incognito browser window without logging in. Check if files can be downloaded or download statistics accessed without authentication.
    Affected if Downloads are accessible without being logged in and without proper capability checks.
  4. Test admin panel access without authorization
    Try accessing WordPress admin area paths related to the plugin (such as wp-admin/admin.php?page=wpdm* or similar) while logged out or as a non-administrator user.
    Affected if Administrative functions or settings pages of the plugin are accessible without proper admin privileges.
  5. Review plugin access control settings
    In WordPress admin, navigate to Download Manager settings (usually under WP Download Manager menu) and examine access control, capability settings, or package access restrictions.
    Affected if Access control settings are configured to allow public or low-privileged user access to sensitive download management features.

A user is affected if the download-manager plugin version is 3.3.52 or lower AND sensitive download functions or admin settings are accessible without proper authentication or authorization checks.
