The Download Manager WordPress plugin before 3.3.66 does not properly escape a package's title before outputting it in the front-end package templates, allowing users with the Author role or above to store a title that results in arbitrary JavaScript execution in the browser of any user, including unauthenticated visitors, who views a page displaying the package.

The Download Manager WordPress plugin before 3.3.62 does not bind its temporary download token to the requesting session nor expire it promptly, making the token a long-lived, multi-use, portable bearer token, so that an attacker who obtains one leaked download key can repeatedly download a role- or password-protected package file without authorization.

This makes it possible for unauthenticated attackers to download password-protected files.

The Download Manager plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the ‘userids’ parameter in all versions up to, and including, 3.3.23 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link.

The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'wpdmallpackages' shortcode in all versions up to, and including, 3.2.97 due to insufficient input sanitization and output escaping on the 'cols' parameter. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The The Download Manager plugin for WordPress is vulnerable to arbitrary shortcode execution in all versions up to, and including, 3.3.03. This is due to the software allowing users to execute an action that does not properly validate a value before running doshortcode. This makes it possible for unauthenticated attackers to execute arbitrary shortcodes.

The Download Manager plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the savePackage function in all versions up to, and including, 3.3.12. This makes it possible for authenticated attackers, with Author-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php).

The Download Manager plugin for WordPress is vulnerable to unauthorized access due to a hardcoded Cron key used in the deleteExpired() and clearTempDataCPCron() functions in all versions up to, and including, 3.3.30. This makes it possible for unauthenticated attackers to trigger these cron jobs leading to deletion of expired posts and clearing cache.

The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's wpdmuserdashboard shortcode in all versions up to, and including, 3.3.18 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

A vulnerability, which was classified as problematic, was found in Download Manager Plugin 2.8.99. Affected is an unknown function. The manipulation leads to cross-site request forgery. It is possible to launch the attack remotely.

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.

Directory traversal vulnerability in the WordPress Download Manager plugin for WordPress allows remote attackers to read arbitrary files via a .. (dot dot) in the fname parameter to (1) views/filedownload.php or (2) filedownload.php.

Open redirect vulnerability in WordPress Download Manager prior to version 2.9.51 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via unspecified vectors.

Cross-site scripting vulnerability in WordPress Download Manager prior to version 2.9.50 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

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 wpdmsavetemplate 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 unfilteredhtml capability is disallowed

Authenticated File Upload in WordPress Download Manager <= 3.1.24 allows authenticated (Author+) users to upload files with a double extension, e.g. "payload.php.png" which is executable in some configurations. This issue affects: WordPress Download Manager version 3.1.24 and prior versions.

Authenticated Directory Traversal in WordPress Download Manager <= 3.1.24 allows authenticated (Contributor+) users to obtain sensitive configuration file information, as well as allowing Author+ users to perform XSS attacks, by setting Download template to a file containing configuration information or an uploaded JavaScript with an image extension This issue affects: WordPress Download Manager version 3.1.24 and prior versions.

The download-manager plugin before 2.9.94 for WordPress has XSS via the category shortcode feature, as demonstrated by the orderby or search[publishdate] parameter.

The download-manager plugin before 2.9.52 for WordPress has XSS via the id parameter in a wpdmgeneratepassword action to wp-admin/admin-ajax.php.

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 3.2.50 prioritizes getting a visitor's IP from certain HTTP headers over PHP's REMOTEADDR, which makes it possible to bypass IP-based download blocking restrictions.

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.
