Summary
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.
Risk Assessment
Attackers can inject malicious scripts that execute in visitors' browsers, potentially leading to session theft or other attacks.
Recommendation
Update the Download Manager plugin to the latest version that includes a fix for this vulnerability.
Other vulnerabilities in Download Manager
See all- CVE-2026-92714Medium
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.
- CVE-2026-16685Medium
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.
- CVE-2026-14292Medium
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.
- CVE-2026-14343Medium
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.
- CVE-2026-13733Medium
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.
- CVE-2026-39676Medium
The Download Manager plugin for WordPress has a missing authorization vulnerability, allowing exploitation of incorrectly configured access control security levels. This issue affects versions up to and including 3.3.52.
- CVE-2026-39615Medium
The Download Manager plugin for WordPress is vulnerable to Stored XSS. An attacker can inject a malicious script that executes in other users' browsers.
Original NVD description (English source)
The Download Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'sid' parameter of the 'wpdm_members' shortcode in versions up to and including 3.3.52. This is due to insufficient input sanitization and output escaping on the user-supplied 'sid' shortcode attribute. The sid parameter is extracted without sanitization in the members() function and stored via update_post_meta(), then echoed directly into an HTML id attribute in the members.php template without applying esc_attr(). 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 the injected page.
