Vulnerability Overview

The Simple Calendar plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.1.42. This is due to missing nonce validation on the clear_cache() function used to clear the plugin's transients. This makes it possible for unauthenticated attackers to clear the plugin's transients for a given id, 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 3.1.43, 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.
