Vulnerability Overview

The Visual Link Preview plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 2.3.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to extract sensitive user or configuration data.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

CWE-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in Visual Link Preview <= 2.3.1 takes an account at Subscriber level or above. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For Visual Link Preview the fix is 2.4.0: builds <= 2.3.1 are affected, anything from 2.4.0 onward is not.

Remediation

Update to version 2.4.0, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: Visual Link Preview 2.4.0 closes this, and updating the plugin is the step that ends it.
