Vulnerability Overview

The Blog2Social plugin for WordPress is vulnerable to Server-Side Request Forgery in versions up to, and including, 6.9.9 due to missing URL validation to ensure an external URL is used in the function b2sFileGetContents. This makes it possible for authenticated users, with subscriber-level access or higher, to perform attacks against the server.

Technical Analysis

REMEDIATION: Update to version 6.9.10, 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.
