Vulnerability Overview

The AnyComment plugin for WordPress is vulnerable to Open Redirect in versions up to, and including, 0.3.4. This is due to an API endpoint which passes user input via the redirect parameter to the wp_redirect() function without being validated first. This makes it possible for unauthenticated attackers to create redirect links using the site.

Technical Analysis

REMEDIATION: Update to version 0.3.5, 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.
