The GeoDirectory – WP Business Directory Plugin and Classified Listings Directory plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'business_hours' parameter in all versions up to, and including, 2.8.183 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is possible because the AJAX save handler validates only post authorship and a nonce with no additional capability check, allowing any subscriber-level user who owns a listing to exploit this vulnerability.
