Descriptions

The Editorial Calendar WordPress plugin before 3.8.3 does not sanitise and escape its settings, allowing users with roles as low as contributor to inject arbitrary web scripts in the plugin admin panel, enabling a Stored Cross-Site Scripting vulnerability targeting higher privileged users.

The Editorial Calendar plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘wheel-support’ parameter accepted by the 'edcal_saveoptions' AJAX action in versions up to, and including, 3.8.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with contributor-level permissions or above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
