🔐 CVE-2026-48908 Scanner & Safe PoC

📌 About

This project is a security research and vulnerability detection tool developed by yora to help identify CVE-2026-48908 affecting SP Page Builder for Joomla.

The vulnerability is related to an unauthenticated file upload mechanism. Under vulnerable conditions, an attacker may be able to upload an unexpected file type, potentially leading to Remote Code Execution (RCE).

⚠️ Important: Use this project only against systems you own or systems for which you have explicit authorization to perform security testing.

Affected Versions

• Affected: SP Page Builder 1.0.0 through 6.6.1
• Fixed: SP Page Builder 6.6.2 and later

✨ Features

The public documentation intentionally does not provide a weaponized shell, command-execution URL, or instructions for obtaining unauthorized access.

🚀 Installation

Clone Repository

git clone https://github.com/yora1928/CVE-2026-48908-by-yora.git
cd CVE-2026-48908-by-yora

Install Dependencies

python -m pip install -r requirements.txt

requirements.txt

requests>=2.28.0

📖 Usage

1. Detection Only

Use the scanner in detection mode against an authorized target:

python scanner.py --url https://your-authorized-target.example

Example result:

[CONFIRMED] https://your-authorized-target.example
    ├─ SP Page Builder detected
    ├─ Version: 6.3.1
    └─ Vulnerable version and relevant endpoint exposure detected

2. Authorized Validation / PoC

The project can be used for controlled validation in a laboratory or authorized environment.

The purpose of validation is to establish whether the vulnerable upload behavior is present without turning the documentation into a ready-to-use remote shell.

python scanner.py --url https://your-authorized-target.example --exploit

For safe research, use an isolated test environment and inspect the generated evidence and report rather than attempting to access systems without authorization.

3. Scan Multiple Authorized Targets

Create targets.txt:

https://site1.example
https://site2.example

Run:

python scanner.py --list targets.txt --threads 5

Only include systems that you are authorized to test.

4. Save Results as JSON

python scanner.py --url https://your-authorized-target.example --output reports/result.json

5. Cleanup

After authorized testing, review the generated evidence and remove any test artifacts from the target.

python scanner.py --url https://your-authorized-target.example --exploit --cleanup

If the tool reports an artifact location, verify it against your test environment and remove it using your normal authorized administration method.

🔎 Vulnerability Overview

What is CVE-2026-48908?

CVE-2026-48908 affects SP Page Builder for Joomla and is associated with an unauthenticated file upload vulnerability.

The security issue is significant because an unrestricted or insufficiently validated upload mechanism can allow an attacker to place an executable file on a server.

If the uploaded file is interpreted by the server, the vulnerability may lead to:

Unauthenticated File Upload → Server-Side File Placement → Potential Code Execution → Possible Server Compromise

💥 Potential Impact

A vulnerable installation may face risks including:

• Unauthorized file uploads
• Remote Code Execution
• Server compromise
• Unauthorized modification of application files
• Potential exposure of application data
• Website defacement
• Loss of confidentiality, integrity, or availability

The actual impact depends on the server configuration, permissions, PHP environment, Joomla configuration, and other security controls.

🛡️ Mitigation

If you are running an affected version:

1. Upgrade SP Page Builder to 6.6.2 or later.
2. Review the server for unexpected uploaded files.
3. Review web server and application logs for suspicious requests.
4. Check Joomla extensions and components for unexpected changes.
5. Rotate credentials if compromise is suspected.
6. Continue monitoring the server after remediation.

🔒 Responsible Use

This project is intended for:

• Security research
• Vulnerability validation
• Authorized penetration testing
• Education
• Defensive security assessment
• Testing in isolated laboratories

Do not use this project to:

• Scan random internet targets without permission
• Upload files to systems you do not control
• Obtain unauthorized access
• Maintain persistence on compromised systems
• Collect credentials or private information
• Disrupt services

Authorization matters. Always obtain permission before testing a system that you do not own.
