 "title": "s2Member <= 261011 - Authenticated (Contributor+) Stored Cross-Site Scripting via s2Get Shortcode",
 "description": "The s2Member plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the [s2Get] shortcode in all versions up to, and including, 261011 due to insufficient output escaping of the formatted 'date_format' output and of returned constant and user field values. 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.",
