CVE-2026-104909 Details
Description
The Mang Board plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 2.4.3 via the '<mode>_type (e.g. foo_type)' parameter parameter. This makes it possible for unauthenticated attackers to include and execute arbitrary .php files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where .php file types can be uploaded and included. Exploitation is trivial via an unauthenticated POST to any page rendering a public [mb_board] shortcode, as no nonce or capability check is enforced on the shortcode render path; on servers with a standard PHP installation, pearcmd.php can be leveraged to write and then include an attacker-controlled payload file in a single request.
A local file inclusion vulnerability has been identified in the Mang Board plugin for WordPress, affecting all versions through 2.4.3. The vulnerability arises from the '<mode>_type' parameter, which allows unauthenticated attackers to include and execute arbitrary PHP files on the server. This exploitation could bypass access controls, access sensitive data, or execute code in cases where PHP files can be uploaded and included. The vulnerability can be easily exploited by sending an unauthenticated POST request to any page that uses the public [mb_board] shortcode, as there are no nonce or capability checks in place. On servers with a standard PHP installation, the 'pearcmd.php' file can be used to write and include an attacker-controlled payload in a single request.
Users are advised to update the Mang Board plugin to version 2.4.4 or later.
