Vulnerability Overview

In the GetPaid WordPress plugin before 2.3.4, users with the contributor role and above can create a new Payment Form, however the Label and Help Text input fields were not getting sanitized properly. So it was possible to inject malicious content such as img tags, leading to a Stored Cross-Site Scripting issue which is triggered when the form will be edited, for example when an admin reviews it and could lead to privilege escalation.

Technical Analysis

REMEDIATION: Update to version 2.3.4, or a newer patched version --- IDENTIFIER: CWE-79 (Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')) The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
