CVE-2026-96871
What it is
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.
