CVE-2026-96871
HighCVSS 7.2Exploitation Probability (EPSS)
Low risk14th percentile - higher than 14% of all known CVEs
Summary
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 is exploitable on any board configured with the default write_level=0 and editor_type=N settings.
Risk Assessment
An unauthenticated attacker can inject malicious scripts that execute in the browser of users visiting affected pages, potentially leading to data theft or session hijacking.
Recommendation
Update the Mang Board plugin to the latest patched version and consider changing default board settings to reduce risk.
Other vulnerabilities in Mang Board
See all- CVE-2026-107751High
The Mang Board plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'user_name' parameter in all versions up to and including 2.4.3 due to insufficient input sanitization and output escaping. The save-time sanitizer mbw_htmlspecialchars2() is ineffective because the exploit payload relies solely on unquoted HTML attribute syntax using only spaces, alphanumerics, and characters such as =, parentheses, and dots.
- CVE-2026-104909High
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' parameter. This allows unauthenticated attackers to include and execute arbitrary .php files on the server, enabling access control bypass, sensitive data disclosure, or code execution. Exploitation is trivial via an unauthenticated POST to any page rendering a public [mb_board] shortcode, and on standard PHP installations pearcmd.php can be leveraged to write and include an attacker-controlled payload in a single request.
- CVE-2026-104761Medium
The Mang Board plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'content' parameter in all versions up to, and including, 2.4.3 due to insufficient input sanitization and output escaping. This allows authenticated attackers with custom-level access and above to inject arbitrary web scripts that execute whenever a user accesses an injected page.
Original NVD description (English source)
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.
