The Download Manager Plugin for WordPress is vulnerable to reflected Cross-Site Scripting in versions up to, and including 3.2.42. This is due to insufficient input sanitization and output escaping on the 'frameid' parameter found in the ~/src/Package/views/shortcode-iframe.php file.

The Download Manager WordPress plugin before 3.2.34 uses the uniqid php function to generate the master key for a download, allowing an attacker to brute force the key with reasonable resources giving direct download access regardless of role based restrictions or password protections set for the download.

The Download Manager WordPress plugin before 3.2.35 does not have any authorisation checks in some of the REST API endpoints, allowing unauthenticated attackers to call them, which could lead to sensitive information disclosure, such as posts passwords (fixed in 3.2.24) and files Master Keys (fixed in 3.2.25).

The Download Manager WordPress plugin before 3.2.34 does not sanitise and escape the package_ids parameter before using it in a SQL statement, leading to a SQL injection, which can also be exploited to cause a Reflected Cross-Site Scripting issue

The WordPress Download Manager WordPress plugin before 3.2.22 does not sanitise and escape Template data before outputting it in various pages (such as admin dashboard and frontend). Due to the lack of authorisation and CSRF checks in the wpdm_save_template AJAX action, any authenticated users such as subscriber is able to call it and perform Cross-Site Scripting attacks

The WordPress Download Manager WordPress plugin before 3.2.16 does not escape some of the Download settings when outputting them, allowing high privilege users to perform XSS attacks even when the unfiltered_html capability is disallowed

Internet Download Manager 6.37.11.1 was discovered to contain a stack buffer overflow in the Export/Import function. This vulnerability allows attackers to escalate local process privileges via a crafted ef2 file.

Internet Download Manager 6.37.11.1 was discovered to contain a stack buffer overflow in the Search function. This vulnerability allows attackers to escalate local process privileges via unspecified vectors.
