Welcome Bar <= 2.0.3 - Cross-Site Request Forgery
Strategic Overview
Vulnerability Overview
The Welcome Bar plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.0.3. This is due to missing or incorrect nonce validation on the iwb_do_action function. This makes it possible for unauthenticated attackers to invoke this AJAX action via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
Technical Analysis
REMEDIATION: Update to version 2.0.4, 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.
