Vulnerability Overview

The WP Fastest Cache plugin for WordPress is vulnerable to Server-Side Request Forgery in versions up to, and including, 1.1.4 via the 'check_url' function. This can allow Authenticated attackers with Administrator-level permissions to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services. Note that the function is also vulnerable to Cross-Site Request Forgery but this is only an issue due to the Server-Side Request Forgery capability.

Technical Analysis

REMEDIATION: Update to version 1.1.5, or a newer patched version --- IDENTIFIER: CWE-918 (Server-Side Request Forgery (SSRF)) The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination.
