Description

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.
