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.

Auth. (contributor+) Cross-Site Scripting (XSS) vulnerability in WordPress Download Manager Gutenberg Blocks by WordPress Download Manager plugin <= 2.1.8 versions.

The Download Manager WordPress plugin before 6.3.0 leaks master key information without the need for a password, allowing attackers to download arbitrary password-protected package files.

Unauth. Reflected Cross-Site Scripting (XSS) vulnerability in W3 Eden, Inc. Download Manager plugin <= 3.2.59 versions.

The Download Manager WordPress plugin before 3.2.62 does not validate and escapes some of its shortcode attributes before outputting them back in the page, which could allow users with a role as low as a contributor to perform Stored Cross-Site Scripting attacks against logged-in admins.

The Download Manager plugin for WordPress is vulnerable to deserialization of untrusted input via the 'file[package_dir]' parameter in versions up to, and including 3.2.49. This makes it possible for authenticated attackers with contributor privileges and above to call files using a PHAR wrapper that will deserialize the data and call arbitrary PHP Objects that can be used to perform a variety of malicious actions granted a POP chain is also present. It also requires that the attacker is successful in uploading a file with the serialized payload.

The Download Manager plugin for WordPress is vulnerable to arbitrary file deletion in versions up to, and including 3.2.50. This is due to insufficient file type and path validation on the deleteFiles() function found in the ~/Admin/Menu/Packages.php file that triggers upon download post deletion. This makes it possible for contributor level users and above to supply an arbitrary file path via the 'file[files]' parameter when creating a download post and once the user deletes the post the supplied arbitrary file will be deleted. This can be used by attackers to delete the /wp-config.php file which will reset the installation and make it possible for an attacker to achieve remote code execution on the server.

The Download Manager WordPress plugin before 3.2.50 prioritizes getting a visitor's IP from certain HTTP headers over PHP's REMOTE_ADDR, which makes it possible to bypass IP-based download blocking restrictions.
