Vulnerability Overview

The module cerdic/csstidy, which is used in several plugins, is vulnerable to Server-Side Request Forgery due to the inclusion of test code that does not verify a user-provided URL. This can allow unauthenticated attackers to to make web requests to arbitrary locations originating from the web application which can be used to query and modify information from internal services.

Technical Analysis

REMEDIATION: Update to version 2.7, 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.
