Scramble generates API documentation for Laravel project. From 0.13.2 to before 0.13.22, when documentation endpoints are publicly accessible and validation rules reference user-controlled input, request supplied data may be evaluated during documentation generation, leading to execution of arbitrary PHP code in the application context. This vulnerability is fixed in 0.13.22.

Affected: Packagist: dedoc/scramble

### Impact

A remote code execution (RCE) vulnerability affects versions `0.13.2` through `0.13.21`. When documentation endpoints are publicly accessible and validation rules reference user-controlled input, request supplied data may be evaluated during documentation generation, leading to execution of arbitrary PHP code in the application context.

### Patches

Fixed in version `0.13.22`.

### Workarounds

If upgrading is not immediately possible:

* Restrict access to documentation endpoints (`/docs/api`, `/docs/api.json`) * Avoid using user-controlled variables inside validation rule expressions (e.g., values derived from request input) * Disable documentation endpoints in production environments if not required

These measures significantly reduce or prevent exploitability.
