CVE-2023-27460 is a medium-severity Missing Authorization vulnerability in the CP Contact Form with PayPal WordPress plugin, affecting versions <= 1.3.34. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account. The issue is fixed in version 1.3.35; sites on affected versions should update now. Disclosed March 2023, reported by István Márton.

Vulnerability Overview

The CP Contact Form with Paypal plugin for WordPress is vulnerable to missing authorization on the 'cpcfwpp_feedback' function in versions up to, and including, 1.3.34. This allows authenticated attackers, with subscriber-level capabilities or above, to submit feedback to the plugin developers, which is intended to be a functionality reserved for administrators.

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-862: Missing Authorization

CP Contact Form with PayPal <= 1.3.34 carries this weakness at cpcfwpp_feedback, and reaching it takes any authenticated account. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For CP Contact Form with PayPal the fix is 1.3.35: builds <= 1.3.34 are affected, anything from 1.3.35 onward is not.

Remediation

Update to version 1.3.35, or a newer patched version

How does WordSec protect against this?

Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: CP Contact Form with PayPal 1.3.35 closes this, and updating the plugin is the step that ends it.
