Vulnerability Overview

The Calculated Fields Form plugin for WordPress is vulnerable to Open Redirect via the plugin's shortcode(s) in all versions up to 1.2.29 (exclusive) due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers with contributor-level and above permissions to redirect users when they visit an injected page.

Technical Analysis

REMEDIATION: Update to version 1.2.29, or a newer patched version --- IDENTIFIER: CWE-601 (URL Redirection to Untrusted Site ('Open Redirect')) The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
