CVE-2026-39676

The Download Manager plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to and including 3.3.68 via the duplicate() function hooked on admin_init. This is due to the handler only verifying the generic 'edit_posts' capability and a plugin-wide static nonce without any object-level authorization check. Authenticated attackers with Author-level access or above can duplicate arbitrary Download Manager packages owned by other users, copying all package metadata including protected file references, role-based access restrictions, and password lock settings into an attacker-owned clone.

The Download Manager plugin for WordPress up to version 3.3.66 contains a Stored Cross-Site Scripting (XSS) vulnerability via the 'icon' shortcode attribute. Authenticated attackers with contributor-level access and above can inject arbitrary web scripts that execute whenever a user accesses an injected page.

The Download Manager WordPress plugin before version 3.3.66 does not properly escape a package's title before outputting it in front-end templates. Users with the Author role or higher can 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 plugin for WordPress up to version 3.3.61 inclusive is vulnerable to Stored Cross-Site Scripting via 'note_before' and 'note_after' shortcode attributes due to insufficient input sanitization and output escaping.

The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'no_data_msg' shortcode attribute in all versions up to and including 3.3.60 due to insufficient input sanitization and output escaping. This allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts that execute when a user visits an injected page.

The Download Manager plugin for WordPress up to version 3.3.52 is vulnerable to Stored XSS via the 'sid' attribute of the 'wpdm_members' shortcode. Insufficient input sanitization and output escaping allow attackers with contributor-level access to inject arbitrary scripts.

The Download Manager plugin for WordPress is vulnerable to Stored XSS. An attacker can inject a malicious script that executes in other users' browsers.
