Vulnerability Overview

The Clean Login for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 1.10.3. This is due to missing or incorrect nonce validation on the clean_login_options() function. This makes it possible for unauthenticated attackers to update the plugin's settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. Note this vulnerability was not patched in version 1.8 as stated in the CVE record.

Technical Analysis

REMEDIATION: Update to version 1.10.4, or a newer patched version --- IDENTIFIER: CWE-352 (Cross-Site Request Forgery (CSRF)) The web application does not, or cannot, sufficiently verify whether a request was intentionally provided by the user who sent the request, which could have originated from an unauthorized actor.
