## At a glance

- **Vendor**: ioweb-gr (https://packagento.com/ioweb-gr.md)
- **Latest version**: 1.0.5 — released 2026-03-23
- **Pricing**: Free
- **Package type**: Magento 2 module

## Installation

Packagento is licence-gated, so even free packages need a licence on a project before Composer can resolve them.

1. **Sign in or create an account** at https://packagento.com/customer/account/.

2. **Add the package to your account.** Open https://packagento.com/ioweb-gr/polyshell-disable-file-upload and complete the free checkout. A licence is minted automatically.

3. **Create or pick a project, then activate the licence on it.**
   - Projects represent the Magento installs you deploy to. Manage them at https://packagento.com/projects/.
   - Activate the new licence on the project you'll deploy this package to. Activation is what generates the Composer credentials scoped to that project.

4. **Add the project credentials to your Magento codebase.**

   Grab the project's public + private key from https://packagento.com/projects/ (open the project, then its Credentials tab), and add them to `auth.json`:

   ```json
   {
     "http-basic": {
       "packagento.com": {
         "username": "ppk_live_...",
         "password": "psk_live_..."
       }
     }
   }
   ```

   Add the Packagento Composer repository to `composer.json`:

   ```json
   {
     "repositories": [
       { "type": "composer", "url": "https://packagento.com" }
     ]
   }
   ```

5. **Install and apply.**

   ```bash
   composer require ioweb-gr/polyshell-disable-file-upload:*
   bin/magento setup:upgrade
   bin/magento setup:di:compile
   bin/magento cache:flush
   ```

## What it does

Magento 2 module that disables file custom option uploads as a temporary PolyShell mitigation.

## README

Temporary Magento 2 hardening module that mitigates PolyShell-style abuse until the store is upgraded and fully patched.

### What it provides

The module includes three practical protections:

- A hard block for file custom option uploads.
- A narrower image-extension-only mitigation inspired by [Mark Shust's workaround](https://github.com/markshust/magento-polyshell-patch).
- A CLI command to scan and optionally clear files from `pub/media/custom_options`.

### Admin configuration

Configuration is available at:

`Stores > Configuration > Security > PolyShell Protection`

#### Disable PolyShell Uploads

When enabled, the module hard-blocks file custom option uploads:

- REST and API-driven file custom option payloads are rejected.
- Standard Magento file custom option validation is rejected too.

Use this if the store does not rely on file custom options at all.

#### Allow Only Image Extensions

When enabled, the module applies an image-only extension allowlist to the relevant Magento image upload path:

- rejects non-image filename extensions during image content validation
- restricts the uploader to `jpg`, `jpeg`, `gif`, and `png`

Use this if you want a narrower mitigation and still need image-only behavior.

### Default configuration

For safety, both protections default to `Yes`.

### CLI command

The module adds this command:

```bash
bin/magento ioweb:polyshell:custom-options:scan
```

Behavior:

- Dry-run by default: lists files under `pub/media/custom_options` that would be removed.
- Deletes only when `--force` is supplied.
- Ignores `.htaccess` and `.gitignore`.

Example:

```bash
bin/magento ioweb:polyshell:custom-options:scan --force
```

### Installation

Add the repository to your project and require the package:

```bash
composer config repositories.ioweb-polyshell-disable-file-upload vcs https://github.com/ioweb-gr/polyshell-disable-file-upload.git
composer require ioweb-gr/polyshell-disable-file-upload
bin/magento module:enable Ioweb_PolyshellDisableFileUpload
bin/magento setup:upgrade
bin/magento cache:flush
```

### Notes

- This module is a temporary mitigation, not a replacement for upgrading Magento.
- Keep web server protections on `/media/custom_options/` in place even with this module installed.
- If your store genuinely uses file custom options, test carefully before enabling the hard block mode.

## Recent Versions

| Version | Released |
|---|---|
| 1.0.5 | 2026-03-23 |
| 1.0.4 | 2026-03-23 |

## Dependencies

### Require

| Package | Constraint |
|---|---|
| php | >=7.4 |

## Quality

Latest release (1.0.5) fails the Packagento QA pipeline. Verdicts below are per-cell (Magento line × PHP version) for the matrixed tools, and run-once for the static / security tiers.


### Compatibility

Each Magento line is installed on its supported PHP versions, then the module is built (DI compile + static-content deploy). Cells show passed / failed / untested; staircase gaps render as `–`.

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | Pass | Pass | – | – |
| 2.4.8 | – | Pass | Pass | – |
| 2.4.9 | – | – | Pass | Pass |


### Code Quality

Advisory checks against the module's source. Never affect the Compatibility verdict — a phpcs finding can't make a module incompatible.

#### Static Analysis

Coding standards (phpcs), mess detection (phpmd), copy-pasted code (cpd), PHP cross-version compatibility, composer.json validity. Each runs once for the whole module.

| Tool | Status | Findings | Summary |
|---|---|---|---|
| PHPCS | Warning | 2 | 2 warnings (ruleset: Magento2) — 1 auto-fixable with phpcbf |
| PHPMD | Warning | 5 | 5 rule violations (UnusedFormalParameter:5) |
| Cpd | Pass | 0 |  |
| Composer validate | Info | 1 | valid; 1 advisory note (composer validate --strict) |

#### PHPStan

Type-checks the module against a real Magento install. Re-runs per Magento + PHP version because resolvable symbols differ between releases.

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | 1 | 1 | – | – |
| 2.4.8 | – | 1 | 1 | – |
| 2.4.9 | – | – | 1 | 1 |


### Tests

Unit and integration suites run per Magento + PHP cell. Test failures speak to the module's behaviour, not its compatibility with a line, so they're reported here separately.

#### Unit Tests

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | N/A | N/A | – | – |
| 2.4.8 | – | N/A | N/A | – |
| 2.4.9 | – | – | N/A | N/A |

#### Integration Tests

| Magento | PHP 8.2 | PHP 8.3 | PHP 8.4 | PHP 8.5 |
|---|---|---|---|---|
| 2.4.7 | N/A | N/A | – | – |
| 2.4.8 | – | N/A | N/A | – |
| 2.4.9 | – | – | N/A | N/A |


### Security

Dependency-advisory audit (composer audit) plus a source malware scan. A malware detection fails the version outright.

| Tool | Status | Findings | Summary |
|---|---|---|---|
| Composer audit | Pass | 0 |  |
| Malware scan | Pass | 0 |  |

## Licence and pricing

Free. A licence is still minted on checkout and bound to your project for Composer access — no payment step.

Refundable within 14 days of first purchase via https://packagento.com/account/refunds/.

## Install via Claude Code or any MCP client

The Packagento MCP server can run the licence + project + Composer steps above in one tool call:

```
purchase_and_install_packages(
  composer_names=["ioweb-gr/polyshell-disable-file-upload"],
  project_id="proj_xxx"
)
```

This handles cart, checkout, licence minting, project activation, and writes auth.json credentials. Connect a client with `claude mcp add packagento https://mcp.packagento.com`. Full setup at https://packagento.com/docs/mcp-setup.
