Vulnerability Overview

Unvalidated input and lack of output encoding in the Themify Portfolio Post WordPress plugin, versions before 1.1.6, lead to Stored Cross-Site Scripting (XSS) vulnerabilities allowing low-privileged users (Contributor+) to inject arbitrary JavaScript code or HTML in posts where the Themify Custom Panel is embedded, which could lead to privilege escalation.

Technical Analysis

REMEDIATION: Update to version 1.1.6, 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.
