source listed>= 5.0.0, < 5.0.13
### Impact It’s a “*moderate*” vulnerability… but being an admin panel, take this seriously. It’s difficult… but an attacker could conduct a targeted phishing campaign, in order to **trick your users or admins to click a malicious link, which under very specific circumstances could give them information... or even admin access**. It’s *unlikely*, but that’s not good enough in admin panels - It should be made *impossible*. That’s why you are bothered with this. ### Patches If you don’t have custom error views, the views provided by Backpack would output the exception message *without escaping it*, which made an attack possible using Reflected XSS, in some very specific circumstances (that we will not disclose). **To fix those error views in Backpack 4.x and 5.x, please run**: ```bash composer update backpack/crud php artisan backpack:fix ``` The problem has been patched in: - v4.0.63 - v4.1.69 - v5.0.13 > **IMPORTANT! Running a `composer update` should get you the patched version, but you also need to run `php artisan backpack:fix` afterwards, to patch your published error views, if necessary.** ### Workarounds Alternatively (if you don’t want to run `composer update`), yo
