Vulnerability Overview

The Images Optimize and Upload CF7 plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on the yr_api_delete AJAX action available to unprivileged users in versions up to, and including, 2.1.4. This makes it possible for unauthenticated attackers to delete arbitrary files. This could be used to delete the wp-config.php file that would make complete site takeover relatively simple for an attacker.

Technical Analysis

REMEDIATION: Update to version 2.2.1, or a newer patched version --- IDENTIFIER: CWE-862 (Missing Authorization) The product does not perform an authorization check when an actor attempts to access a resource or perform an action.
