Cross-Site Scripting (XSS) in backpack/crud (CVE-2026-54181)

Summary

Cross-site scripting in backpack/crud (CVE-2026-54181). Risk of unauthorized operations or information disclosure. Exploitable via color. Mitigation: upgrade to 7.0.38 or later.

Original description

The description as published by the source.

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.

Response actions

Concrete steps and command examples for SOC/SRE teams to execute in order

  1. 1
    Identify exposure identify 
    grep -r 'backpack/crud' . | grep -v node_modules

    リポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で backpack/crud を grep し、稼働しているサービス・バージョンを把握する。

  2. 2
    Apply temporary workaround mitigate 
    Validate stored color values against a strict CSS color grammar (e.g.

    パッチが適用されるまでの応急処置として、Validate stored color values against a strict CSS color grammar (e.g. を実施。回避策の副作用 (機能低下) を確認した上で。

  3. 3
    Apply patch patch 
    Upgrade backpack/crud to 7.0.38

    ステージング環境で 7.0.38 に上げて回帰テスト → 本番反映。回帰テストはアプリの主要ハッピーパスを含めること。

  4. 4
    Post-deployment verification verify 
    Confirm patched version is live in production

    パッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番ではアクセスログ・WAF でアラート再発が無いか継続監視。
