Vulnerability Overview

The VR Calendar plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 2.3.3. This is due to missing or incorrect nonce validation on several functions. This makes it possible for unauthenticated attackers to delete, and modify calendars as well as the plugin settings, via 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 2.3.4, 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.
