In SyliusResourceBundle before versions 1.3.14, 1.4.7, 1.5.2 and 1.6.4, request parameters injected inside an expression evaluated by `symfony/expression-language` package haven't been sanitized properly. This allows the attacker to access any public service by manipulating that request parameter, allowing for Remote Code Execution. This issue has been patched for versions 1.3.14, 1.4.7, 1.5.2 and 1.6.4. Versions prior to 1.3 were not patched.

GHSA-h6m7-j4h3-9rf5 — Remote Code Execution in SyliusResourceBundle

Affected: Packagist: sylius/resource-bundle

### Impact

Request parameters injected inside an expression evaluated by `symfony/expression-language` package haven't been sanitized properly. This allows the attacker to access any public service by manipulating that request parameter, allowing for Remote Code Execution.

The vulnerable versions include: `<=1.3.13 || >=1.4.0 <=1.4.6 || >=1.5.0 <=1.5.1 || >=1.6.0 <=1.6.3`.

### Example

```yaml sylius_grid: grids: foo: fields: bar: options: baz: "expr:service('sylius.repository.product').find($id)" ```

In this case, `$id` can be prepared in a way that calls other services.

If you visit `/route?id="~service('doctrine').getManager().getConnection().executeQuery("DELETE * FROM TABLE")~"`, it will result in a following expression `expr:service('repository').find(""~service('doctrine').getManager().getConnection().executeQuery("DELETE * FROM TABLE")~"")`, which will execute a query on the currently connected database.

To find a vulnerability in your application, look for any routing definition that uses request parameters inside expression language.

### Patches

This issue has been patched for versions 1.3.14, 1.4.7, 1.5.2 and 1.6.4. Versions prior to 1.3 were not patched.

### Workarounds

The fix requires adding `addslashes` in `OptionsParser::parseOptionExpression` to sanitize user input before evaluating it using the expression language.

```php - return is_string($variable) ? sprintf('…
