Strategic Overview

Vulnerability Overview

The Under Construction, Coming Soon & Maintenance Mode plugin for WordPress is vulnerable to Server Side Request Forgery (SSRF) in versions up to, and including,1.1.1. This is due to the 'apiKey' POST parameter being improperly sanitized. This makes it possible for unauthenticated attackers to execute arbitrary scripting in other users' browsers, leading to the disclosure of sensitive data or subsequent attacks.

Technical Analysis

REMEDIATION: Update to version 1.1.2, 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.
