Vulnerability in djust (CVE-2026-61594)

Summary

Vulnerability in djust (CVE-2026-61594). Confidential information can be exposed externally. Exploitable via check_view_auth. Mitigation: upgrade to 1.0.7 or later.

Original description

The description as published by the source.

Impact

The live (WebSocket) transport authorizes a mount via check_view_auth, not Django's View.dispatch() chain. As a result, standard Django authorization — LoginRequiredMixin, PermissionRequiredMixin, UserPassesTestMixin, @method_decorator(login_required, name="dispatch"), and custom dispatch() guards — and the djust admin extension's staff gate (applied only in the HTTP as_view wrapper) were enforced on the initial HTTP GET but silently bypassed over WebSocket, where all events and state flow. An anonymous or under-privileged client could open a WebSocket and mount such a view — including admin list/create/change/delete — and dispatch its handlers.

Patches

Fixed in djust 1.0.7. check_view_auth now honors the Django AccessMixin family on every transport; a new system check S004 fails loud at startup on auth patterns the runtime cannot safely replay (decorator/overridden-dispatch forms); and the admin base mixin declares login_required = True + an active-staff check_permissions gate.

Workarounds

Gate views using djust's login_required / permission_required / check_permissions attributes (honored on all transports) rather than HTTP-only mixins/decorators.

🔥 Severity

Severity: Critical (CVSS 9.1/10). Confidential information can be exposed externally.

🔧 How to fix

Update to 1.0.7.

🛡️ Workaround

Workaround: Gate views using djust's login_required / permission_required / check_permissions attributes (honored on all transports) rather than HTTP-only mixins/decorators.

🔍 Detection

Search webserver/proxy logs for unusual request patterns matching this CVE's known IOCs. Run grep -r 'djust' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.

Response actions

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

  1. 1
    Identify exposure identify 
    grep -r 'djust' . | 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 djust 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 
    Gate views using djust's `login_required` / `permission_required` / `check_permissions` attributes (honored on all transports) rather than HTTP-only mixins/decorators.

    パッチが適用されるまでの応急処置として、Gate views using djust's login_required / permission_required / check_permissions attributes (honored on all transports) rather than HTTP-only mixins/decorators. 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 djust to 1.0.7

    ステージング環境で 1.0.7 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。
