**WordPress XSS Vulnerability Assessment, Remediation & Whitepaper**
A lab-verified security assessment of two WordPress XSS vulnerabilities (CVE-2026-1512 and CVE-2026-1404), including full exploitation proof-of-concept, attack chain analysis, and a cross-platform remediation tool. All exploitation was performed exclusively on privately owned, isolated lab equipment โ no live websites were tested.
This repository demonstrates how offensive security techniques โ vulnerability reproduction, payload engineering, and attack chain mapping โ are applied defensively to protect real-world WordPress installations. The research establishes the actual exploitability of published CVEs rather than relying on theoretical risk assessments.

## Quick Start: wp-fix
Download the binary for your platform from [Releases](https://github.com/nestorwheelock/wordpress-vulnerability-fix/releases), then:
```sh
# Full pipeline: check โ audit โ update โ verify
./wp-fix all
# Or run individual steps
./wp-fix check # Report plugin versions, flag vulnerable ones
./wp-fix audit # Scan Elementor data for injected XSS payloads
./wp-fix update # Update vulnerable plugins
./wp-fix verify # Confirm patched versions installed
```
### Platform Downloads
| Platform | Binary | Default WordPress Path |
|----------|--------|------------------------|
| Linux x86_64 | `wp-fix-linux-x86_64` | `/var/www/html` |
| FreeBSD x86_64 | `wp-fix-freebsd-x86_64` | `/usr/local/www/wordpress` |
| Windows x86_64 | `wp-fix-windows-x86_64.exe` | `C:\xampp\htdocs\wordpress` |
Custom paths: `./wp-fix all --wp-path /srv/wordpress --wp-cli /usr/bin/wp`
## Why a Compiled Binary
WordPress remediation is typically done with shell scripts. Shell scripts break: quoting bugs, portability issues across bash/sh/zsh, no error types, silent failures, no test suites. A shell script that works on Ubuntu doesn't work on FreeBSD.
wp-fix is a compiled Rust binary:
- **Single file, zero dependencies** โ copy to any server and run. No interpreter, no PATH issues, no "which version of bash"
- **Memory safe** โ Rust's ownership system prevents buffer overflows, use-after-free, and null pointer crashes. The compiler catches bugs before deployment
- **38 unit tests** โ version comparison, CSV parsing, XSS pattern detection, argument handling all verified before every build
- **Cross-platform** โ one codebase compiles for Linux, FreeBSD, and Windows. Platform-specific defaults selected at compile time
- **Structured exit codes** โ 0 (clean), 1 (vulnerabilities found), 2 (error). Suitable for cron and monitoring integration
## wp-fix Commands
| Command | Description |
|---------|-------------|
| `check` | Scan installed plugin versions against known-vulnerable database |
| `audit` | Detect XSS payloads in Elementor widget data (9 pattern types) |
| `update` | Update targeted vulnerable plugins via wp-cli or direct download |
| `update-all` | Update ALL outdated plugins (general maintenance) |
| `verify` | Confirm patched versions installed after update |
| `all` | Run full pipeline: check โ audit โ update โ verify |
| `install-wpcli` | Download and install wp-cli if not present |

## The Whitepaper
The [full assessment](docs/whitepaper/wordpress-xss-vulnerability-assessment.md) documents:
1. **Passive discovery methodology** โ how publicly visible HTML source code reveals vulnerable plugin versions to every visitor
2. **Lab reproduction** โ isolated FreeBSD jail replicating the exact production software stack
3. **CVE-2026-1512 exploitation** โ stored XSS in the Essential Addons Login/Register Form widget; zero-click beacon tracking and one-click credential phishing confirmed in lab
4. **CVE-2026-1404 exploitation** โ reflected XSS in Ultimate Member member directory; full JavaScript execution including admin account creation
5. **Social engineering attack scenarios** โ five delivery methods an attacker would use to weaponize CVE-2026-1404
6. **Full offensive attack chain** โ seven phases from initial XSS to credential reuse, mailing list weaponization, device compromise, and financial fraud
7. **Risk assessment** โ exploitability vs. exposure matrix
8. **Remediation** โ immediate actions, monitoring, and long-term architectural options
This is a de-identified case study. The original assessment was performed for a specific organization; identifying details have been replaced with generic placeholders.

## Custom Security Analysis
We provide WordPress security assessment and remediation services:
- **Vulnerability Assessment** โ Passive analysis of your WordPress installation's public attack surface, identifying outdated plugins, exposed APIs, and exploitable configurations
- **Lab-Verified Exploitation** โ Isolated reproduction of vulnerabilities found on your site, confirming real-world exploitability with documented proof-of-concept
- **Automated Remediation Deployment** โ wp-fix configured for your specific environment, with monitoring and cron integration
- **Managed WordPress Security** โ Ongoing vulnerability monitoring, patch management, and incident response via fleet management tooling
- **Platform Migration** โ Migration from WordPress to a purpose-built Rust/Axum application that structurally eliminates XSS, CSRF, SQL injection, and plugin supply chain risks
Each engagement begins with a passive assessment (no testing against your live site) and scales to whatever level of remediation and management you need.
