Laravel Backpack CRUD: Stored XSS in the color column — the `@if($column['escaped'])` branches are inverted
Quick fix
GHSA-mmg4-322v-6jvc — backpack/crud: upgrade to the fixed version with the command below.
composer require backpack/crud:^6.8.14 Details
## Summary
The Blade template for the `color` column type (`src/resources/views/crud/columns/color.blade.php`) has its escaped/unescaped rendering branches inverted relative to every other column template in the library. Because `$column['escaped']` defaults to `true`, values stored in color columns are rendered **unescaped by default**, enabling Stored XSS if column values are not validated before storage.
## Details
All other column templates in `src/resources/views/crud/columns/` follow the convention: - `$column['escaped'] == true` → `{{ $column['text'] }}` (HTML-escaped) - `$column['escaped'] == false` → `{!! $column['text'] !!}` (raw)
The `color` template has these branches swapped. An attacker who can write an arbitrary string to a `color`-typed column can inject JavaScript that executes in the browser of any user who views the list — including administrators — with access to their session cookies and CSRF tokens.
## Impact
Stored XSS with scope change (attacker context runs in victim's browser). Highest-risk target is an administrator viewing the list view. Exploitability requires the ability to write an unsanitized value into a `color`-typed column.
## Patches
Fixed in **6.8.14** and **7.0.38** by correcting the branch order in `color.blade.php`. See PR #5992.
## Workarounds
Validate stored color values against a strict CSS color grammar (e.g. `/^#[0-9a-fA-F]{3,6}$/`) at the model layer before data reaches the view.
