Vulnerability Overview

The One to one user Chat by WPGuppy plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the /wp-json/guppylite/v2/channel-authorize rest endpoint in all versions up to, and including, 1.1.4. This makes it possible for unauthenticated attackers to intercept and view private chat messages between users.

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 privileges on the target site, and no interaction from a victim user.

CWE-306: Missing Authentication for Critical Function

The product does not perform any authentication for functionality that requires a provable user identity or consumes a significant amount of resources.

Remediation

No known patch available. Please review the vulnerability's details in depth and employ mitigations based on your organization's risk tolerance. It may be best to uninstall the affected software and find a replacement.

How does WordSec protect against this?

This one needs no account at all, which puts it outside what login hardening can reach; WordSec's login security narrows the account-level paths around it, and the firewall is what inspects the request itself. No patched version is recorded yet, which is the case where a filtering layer matters most, because there is nothing to update to.
