## Affected

- Laravel-Backpack CRUD: from 5.0.0, fixed in 5.0.13; from 4.0.0, fixed in 4.1.69; fixed in 4.0.63
- backpack/crud (Packagist): from 5.0.0, fixed in 5.0.13
- backpack/crud (Packagist): from 4.1.0, fixed in 4.1.69
- backpack/crud (Packagist): fixed in 4.0.63

## Description

backpack/crud provides Create, Read, Update & Delete (CRUD) functions for Backpack, a collection of Laravel packages that help users build custom administration panels. Versions prior to 5.0.13, 4.1.69, and 4.0.63 are vulnerable to cross-site scripting. An attacker could conduct a targeted phishing campaign, in order to trick users or admins into clicking a malicious link, which under very specific circumstances could give them information or possibly admin access. Versions 5.0.13, 4.1.69, and 4.0.63 patch the issue. As a workaround, manually look inside error views in `resources/views/errors` and output `e($exception->getMessage())` instead of `$exception->getMessage()`.

## What to do

- Check your stack: if you ship or depend on Laravel-Backpack CRUD, backpack/crud, upgrade to a fixed version (5.0.13, 4.1.69, 4.0.63) per the references below.
