CVE-2026-110071

medium

Description

The Mang Board plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'align' parameter in all versions up to, and including, 2.4.5 due to insufficient input sanitization and output escaping. 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 an injected page. Because the payload contains no angle brackets, wp_kses_post leaves the shortcode intact on save, allowing the malicious attribute value to survive post submission and fire in any viewer's browser — including an administrator previewing a pending post.
