The Download Manager plugin for WordPress is vulnerable to unauthorized file download of files added via the plugin in all versions up to, and including, 3.2.84. This makes it possible for unauthenticated attackers to download files added with the plugin (even when privately published).

The Download Manager WordPress plugin before 3.2.83 does not protect file download's passwords, leaking it upon receiving an invalid one.

The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'wpdm_members', 'wpdm_login_form', 'wpdm_reg_form' shortcodes in versions up to, and including, 3.2.70 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Download Manager WordPress plugin before 3.2.71 does not adequately validate passwords for password-protected files. Upon validation, a master key is generated and exposed to the user, which may be used to download any password-protected file on the server, allowing a user to download any file with the knowledge of any one file's password.
