Loading vulnerability…
A stored cross-site scripting (XSS) vulnerability exists in the Formidable Form Builder plugin for WordPress prior to version 2.05.03. The vulnerability is due to insufficient input sanitization and output escaping on multiple parameters, such as 'after_html', submitted during form entries. This allows unauthenticated attackers to inject arbitrary JavaScript or HTML code, which is then stored and executed in the context of users viewing the affected forms.

This repository provides a reproducible Docker-based lab for demonstrating CVE-2017-20192, a stored XSS vulnerability in Formidable Forms for WordPress (versions < 2.05.03). The structure includes a docker-compose file to set up MySQL and WordPress containers, with a custom initialization script (scripts/wp-init.sh) that installs and configures WordPress and the vulnerable plugin version, and creates a test form. The main exploit logic is in scripts/poc.sh, a Bash script that automates the process of submitting a crafted XSS payload to the form (unauthenticated), logging in as admin, and verifying if the payload executes in the admin entry view. The exploit demonstrates the vulnerability by checking for a JavaScript alert containing a unique token. The endpoints targeted are all local to the Docker environment, and the payload is a proof-of-concept for stored XSS. The repository is well-structured for lab and educational use, not for weaponization.
