Title

Formidable Kinetic <= 1.1.01 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes

Summary

The Formidable Kinetic plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'kinetic_link' shortcode in versions up to, and including, 1.1.01. This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes (notably 'window', 'class', and 'label') in the FrmKinetic::link() function, which are concatenated directly into HTML attributes of an anchor tag. 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.

Severity

6.4 (Medium)
