Title

backpack/crud: Stored XSS in the color column — the `@if($column['escaped'])` branches are inverted

Summary

backpack/crud provides Create, Read, Update & Delete (CRUD) functions for Backpack, a collection of Laravel packages that help users build custom administration panels. From 6.0.0 until 6.8.14 and 7.0.38, src/resources/views/crud/columns/color.blade.php inverts the escaped and raw rendering branches controlled by $column['escaped'], which defaults to true, causing $column['text'] to be rendered unescaped by default. An attacker who can store an unsanitized value in a color column can execute script in the browser of a user who views the CRUD list, including an administrator, with access to the victim's session-backed application capabilities. Exploitation requires write access to the stored color value and a victim viewing the list. This issue is fixed in versions 6.8.14 and 7.0.38.

GHSA-MMG4-322V-6JVC

Vulnerability from github – Published: 2026-08-20 18:38 – Updated: 2026-08-20 18:38

Summary

Laravel Backpack CRUD: Stored XSS in the color column — the `@if($column['escaped'])` branches are inverted

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.

  "details": "## Summary\n\nThe 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 `$column[\u0027escaped\u0027]` defaults to `true`, values stored in color columns are rendered **unescaped by default**, enabling Stored XSS if column values are not validated before storage.\n\n## Details\n\nAll other column templates in `src/resources/views/crud/columns/` follow the convention:\n- `$column[\u0027escaped\u0027] == true` \u2192 `{{ $column[\u0027text\u0027] }}` (HTML-escaped)\n- `$column[\u0027escaped\u0027] == false` \u2192 `{!! $column[\u0027text\u0027] !!}` (raw)\n\nThe `color` template has these branches swapped. An attacker who can write an arbitrary string to a `color`-typed column can inject JavaScript that executes in the browser of any user who views the list \u2014 including administrators \u2014 with access to their session cookies and CSRF tokens.\n\n## Impact\n\nStored XSS with scope change (attacker context runs in victim\u0027s browser). Highest-risk target is an administrator viewing the list view. Exploitability requires the ability to write an unsanitized value into a `color`-typed column.\n\n## Patches\n\nFixed in **6.8.14** and **7.0.38** by correcting the branch order in `color.blade.php`. See PR #5992.\n\n## Workarounds\n\nValidate stored color values against a strict CSS color grammar (e.g. `/^#[0-9a-fA-F]{3,6}$/`) at the model layer before data reaches the view.\n\n## Credits\n\nReported by Vishal Shukla ([@shukla304](https://github.com/shukla304)) via sechub.dev.",
