Description

The Themify Portfolio Post plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 1.3.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

Summary

The Themify Portfolio Post plugin for WordPress (versions 1.3.0 and below) contains a stored Cross-Site Scripting (XSS) vulnerability. Authenticated users with Author-level permissions or higher can inject arbitrary JavaScript into portfolio post attributes, which then executes in the browser of any user who views the affected content.

Exploit Outline

1. Log in to the WordPress administrative dashboard with credentials for a user having at least 'Author' privileges. 2. Navigate to the Portfolio post type and either create a new portfolio item or edit an existing one. 3. Input a malicious JavaScript payload, such as <script>alert('XSS')</script>, into a portfolio-specific custom field (e.g., project link, title, or other descriptive metadata) that lacks proper sanitization. 4. Save or publish the portfolio post. 5. Navigate to the frontend URL of the portfolio post or the archive page where the metadata is displayed. The script will execute in the context of the user's browser, potentially allowing for session hijacking or further administrative actions.
