### Impact Three issues allowed actions protected by the attribute to run against records the current user is not authorized for: 1. **Out-of-order parameter keys on actions.** resolved a model parameter by its array key, while the action itself received parameters positionally. A request sending params as an object with reordered integer keys (e.g. ) could pass authorization with a record the user owns while the action received a different record. With on , a user could delete another user's comment. 2. **The same issue on event listeners.** Methods using both and with a model parameter were affected in the same way through the call. 3. ** methods ran before authorization.** When a method had both and , the method body executed before the authorization check. The response was still a 403, but any side effects (such as database writes) had already happened. Only applications using the attribute are affected: on methods that take model parameters (issues 1 and 2), or on methods (issue 3). Authorization performed inside the method (e.g. ) is not affected. Livewire 3.x is not affected. ### Patches Fixed in **v4.4.8**. Call and event parameters must now be a list or use named (string) keys, otherwise the request is rejected, and methods are authorized before they run. ### Workarounds Upgrade to v4.4.8. If you can't upgrade right away, call inside affected methods instead of relying on the attribute. ### Credits Reported by Yousef Aman ([@yousef-aman](https://github.com/yousef-aman)).
