GeoDirectory – WordPress Business Directory Plugin, or Classified Directory <= 2.3.48 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'gd_single_tabs' Shortcode

The GeoDirectory – WordPress Business Directory Plugin, or Classified Directory plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'gd_single_tabs' shortcode in all versions up to, and including, 2.3.48 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
