Vulnerability Overview

The JSM file_get_contents() Shortcode plugin for WordPress is vulnerable to Server-Side Request Forgery in versions up to, and including, 2.7.0 via the wpfgc shortcode. This makes it possible for authenticated attackers, with contributor-level permissions and above, to make web requests to arbitrary locations originating from the web application and can be used to query and modify information from internal services.

Technical Analysis

REMEDIATION: Update to version 2.7.1, 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.
