Vulnerability Overview

The Web Stories plugin for WordPress is vulnerable to Server-Side Request Forgery in versions up to, and including 1.24.0 due to insufficient validation of URLs supplied via the 'url' parameter found via the /v1/hotlink/proxy REST API Endpoint. This makes it possible for authenticated users 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 1.25.0, 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.
