The WP MapIt plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'wp_mapit' shortcode in all versions up to, and including, 2.7.1 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
