Vulnerability Overview

The WP Plugin Info Card plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 6.2.0. This is due to missing nonce validation in the ajax_save_custom_plugin() function, which is disabled by prefixing the check with 'false &&'. This makes it possible for unauthenticated attackers to create or modify custom plugin entries 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 6.3.0, 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.
