Vulnerability Overview

The Import feature of the RSVPMaker WordPress plugin before 8.7.4 (/wp-admin/tools.php?page=rsvpmaker_export_screen) takes an URL input and calls curl on it, without first validating it to ensure it's a remote one. As a result, a high privilege user could use that feature to scan the internal network via a SSRF attack.

Technical Analysis

REMEDIATION: Update to version 8.7.4, 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.
