Stored XSS in Mang Board WordPress Plugin

Publication date: 2026-10-02

Last updated on: 2026-10-02

Assigner: Wordfence

Description
The Mang Board plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'data_type' parameter in all versions up to, and including, 2.4.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable on any board configured with the default write_level=0 (guest posting) and editor_type=N settings, which are the out-of-the-box defaults for newly created boards.

Executive Summary

This vulnerability is a Stored Cross-Site Scripting (XSS) issue in the Mang Board plugin for WordPress. It occurs because the 'data_type' parameter does not properly sanitize or escape user input, allowing attackers to inject malicious scripts. These scripts execute when users access infected pages.

Detection Guidance

Check WordPress installations for the Mang Board plugin versions up to 2.4.2. Inspect web server logs for unusual script injections in the 'data_type' parameter. Use tools like WP-CLI to list installed plugins and verify versions.

Impact Analysis

Unauthenticated attackers can inject harmful scripts into pages. If your board allows guest posting (default setting), visitors may have their sessions hijacked, credentials stolen, or malware distributed. The impact depends on user interactions with the compromised pages.

Compliance Impact

This vulnerability could lead to data breaches, violating GDPR (privacy rights) and HIPAA (protected health information). Unauthorized script execution may expose user data, triggering compliance violations and potential legal penalties.

Mitigation Strategies

Update the Mang Board plugin to the latest version. If an update is unavailable, disable the plugin immediately. Configure the plugin to require authentication for posting or adjust write_level settings to prevent guest access.
