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.

Cross-Site Request Forgery (CSRF) vulnerability in W3 Eden Download Manager plugin <= 3.2.48 at WordPress.

Multiple Cross-Site Request Forgery (CSRF) vulnerabilities in W3 Eden Download Manager plugin <= 3.2.48 at WordPress.

The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `file[files][]` parameter in versions up to, and including, 3.2.46 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with contributor level permissions and above to inject arbitrary web scripts on the file's page that will execute whenever an administrator accesses the editor area for the injected file page.

The Download Manager WordPress plugin before 3.2.44 does not escape a generated URL before outputting it back in an attribute of the history dashboard, leading to Reflected Cross-Site Scripting
