Mitigation Strategies Analysis for filamentphp/filament

Mitigation Strategy: Comprehensive Policy Review and Enforcement (Filament-Specific)

Mitigation Strategy: Implement and rigorously enforce Laravel Policies for every Filament resource, page, relation manager, and action. This leverages Filament's built-in integration with Laravel's authorization system.

  • Description:

    1. Identify All Filament Components: List every resource, page, relation manager, and custom action within your Filament application.
    2. Generate Policy Stubs: Use Filament's make:policy command (which is a wrapper around Laravel's) for each identified component. Example: php artisan make:policy PostPolicy for a PostResource.
    3. Define Policy Methods (Filament Actions): Within each policy, meticulously define methods corresponding to Filament's actions: viewAny, view, create, update, delete, restore, forceDelete, and any custom Filament actions you've defined. Each method should return true or false.
    4. Associate Policies (Filament's $policy Property): In each Filament resource (e.g., PostResource), explicitly associate the policy using Filament's $policy property: protected static ?string $policy = PostPolicy::class;. For pages and actions, use Filament's can() method or the $authorization property.
    5. Test with Filament's Testing Helpers: Use Filament's testing helpers (e.g., $this->actingAs($user)->get(PostResource::getUrl('index'))) to test access control within the Filament context. Test with different user roles.
    6. Regular Review (Filament Context): Schedule regular reviews of all policies, specifically considering how they interact with Filament's features.

  • Threats Mitigated:

    • Unauthorized Data Access (High Severity): Filament-specific: Users accessing resources/pages they shouldn't within the Filament admin panel.
    • Unauthorized Data Modification (High Severity): Filament-specific: Users modifying data via Filament's forms and actions without permission.
    • Privilege Escalation (High Severity): Filament-specific: Users gaining access to higher-level Filament functionality (e.g., hidden resources) than intended.
    • Bypassing Business Logic (Medium Severity): Filament-specific: Circumventing intended workflows within Filament's UI.

  • Impact: (Same as before, but focused on the Filament context)

    • Significant risk reduction (80-90%) for all listed threats within the Filament admin panel.

  • Currently Implemented / Missing Implementation: (Adapt to your project, focusing on Filament components)

Mitigation Strategy: Strict can() Method Verification (Filament-Specific)

Mitigation Strategy: Meticulously verify every use of Filament's can() method, ensuring correct permission strings and policy logic within the Filament context.

  • Description:

    1. Identify All Filament can() Calls: Search your Filament-related code (resources, pages, actions, custom components) for all instances of $this->can(), $record->can(), etc.
    2. Verify Permission String (Filament Actions): For each can() call, double-check the permission string. Ensure it exactly matches a method name in the relevant policy and corresponds to a Filament action (e.g., 'update', 'delete', a custom action name).
    3. Verify Policy Logic (Filament Context): Examine the associated policy method. Ensure the logic correctly checks user permissions and considers any Filament-specific context (e.g., resource state, current page).
    4. Unit Test (Filament Helpers): Write unit tests using Filament's testing helpers to specifically target these can() calls within the Filament UI flow.
    5. Code Review (Filament Focus): During code reviews, pay special attention to can() calls within Filament components.

  • Threats Mitigated:

    • Unauthorized Action Execution (High Severity): Filament-specific: Users triggering Filament actions (buttons, form submissions) they shouldn't.
    • Bypassing Authorization Checks (High Severity): Filament-specific: Circumventing Filament's intended authorization flow.
    • Logic Errors in Authorization (Medium Severity): Filament-specific: Mistakes in how authorization is applied within Filament components.

  • Impact: (Same as before, but focused on the Filament context)

    • Significant risk reduction (70-80%) for unauthorized action execution and bypassing checks within Filament.

  • Currently Implemented / Missing Implementation: (Adapt to your project, focusing on Filament components)

Mitigation Strategy: Impersonation Feature Controls (Filament-Specific)

Mitigation Strategy: Implement strict controls and auditing for Filament's built-in impersonation feature (if used).

  • Description:

    1. Disable if Unnecessary: If Filament's impersonation is not absolutely required, disable it via Filament's configuration.
    2. Create a Dedicated Policy (Filament Context): Create an ImpersonationPolicy specifically to control Filament's impersonation feature.
    3. Restrict Impersonation (Filament Users): Limit impersonation to specific, highly trusted roles, and consider further restrictions within the Filament context.
    4. Use Filament's canImpersonate() and canBeImpersonated(): Utilize these methods within your User model (or wherever appropriate) to refine impersonation rules specifically for Filament.
    5. Log All Impersonation Events (Filament Context): Log every impersonation attempt within Filament, including details relevant to the Filament UI.
    6. UI Indicator (Filament UI): Add a clear visual indicator within the Filament UI (e.g., a banner) when impersonation is active. This is a Filament-specific UI concern.
    7. Regular Audits (Filament Logs): Regularly review the impersonation logs, focusing on Filament-related activity.

  • Threats Mitigated:

    • Unauthorized Access via Impersonation (Critical Severity): Filament-specific: Unauthorized access through Filament's impersonation feature.
    • Abuse of Impersonation (High Severity): Filament-specific: Misuse of Filament's impersonation capabilities.
    • Lack of Audit Trail (Medium Severity): Filament-specific: Missing audit trail for impersonation within Filament.

  • Impact: (Same as before, but focused on the Filament context)

    • Drastic risk reduction (90-95%) for unauthorized access via Filament's impersonation.

  • Currently Implemented / Missing Implementation: (Adapt to your project, focusing on Filament's impersonation feature)

Mitigation Strategy: Resource Visibility and Data Exposure Control (Filament-Specific)

Mitigation Strategy: Explicitly control the visibility of Filament resources and the data displayed within Filament's tables, forms, and custom components.

  • Description:

    1. Filament Resource Navigation: Use Filament's $navigationGroup, $navigationSort, and $navigationIcon to organize the navigation menu, but do not rely on these for security.
    2. Authorization for Visibility (Filament's canViewAny()): Use Filament's canViewAny() method (or equivalent authorization checks using can()) in each resource to control whether the resource is accessible at all within Filament.
    3. Filament Table Column Configuration: In each resource's table() method, explicitly define which columns are displayed using Filament's ->columns([...]). Use Filament's hidden() or visible() to conditionally show/hide columns. Use Filament's formatStateUsing() to redact or transform sensitive data before display in Filament's tables.
    4. Filament Form Field Configuration: In each resource's form() method, explicitly define which fields are included. Use Filament's hidden() or visible() to control field visibility. Use Filament's dehydrateStateUsing() to remove sensitive data before saving.
    5. Filament Global Search Configuration: In each resource, use Filament's getGloballySearchableAttributes() to specify which attributes are included in Filament's global search index. Exclude sensitive attributes.
    6. Custom Filament Component Review: For any custom Filament components (custom fields, actions, pages), repeat steps 3-5, ensuring that data is handled securely within the Filament context.

  • Threats Mitigated:

    • Unintentional Data Exposure (High Severity): Filament-specific: Sensitive data displayed in Filament's tables, forms, or other UI elements.
    • Information Disclosure (Medium Severity): Filament-specific: Leaking information through Filament's resource listings or forms.
    • Data Leakage via Global Search (Medium Severity): Filament-specific: Sensitive data exposed through Filament's global search.

  • Impact: (Same as before, but focused on the Filament context)

    • Significant risk reduction (70-80%) for data exposure within Filament's UI.

  • Currently Implemented / Missing Implementation: (Adapt to your project, focusing on Filament components)

Mitigation Strategy: Dependency Updates (Filament and its Ecosystem)

Mitigation Strategy: Keep Filament itself, and any third-party Filament plugins, up-to-date.

  • Description:

    1. Regular composer update: Run composer update regularly, paying specific attention to updates for filament/filament and any packages in the filament/* namespace.
    2. Filament Security Advisories: Subscribe to Filament's official release announcements and security advisories. This is crucial for staying informed about vulnerabilities specific to Filament.
    3. Third-Party Filament Plugin Updates: Regularly check for updates to any third-party Filament plugins you're using.
    4. Automated Dependency Analysis (Filament Focus): Use a tool like Dependabot or Snyk, configuring it to specifically monitor Filament and its related packages.
    5. Dependency Locking: Use composer.lock file.

  • Threats Mitigated:

    • Exploitation of Known Vulnerabilities (High Severity): Specifically, vulnerabilities in Filament itself or its plugins.
    • Introduction of Vulnerabilities via Plugins (Medium Severity): Risks associated with outdated or compromised third-party Filament plugins.

  • Impact:

    • Significant risk reduction (70-80%) for vulnerabilities in Filament and its ecosystem.

  • Currently Implemented / Missing Implementation: (Adapt to your project, focusing on Filament and its plugins)

Mitigation Strategy: Secure Configuration Review (Filament's Configuration)

Mitigation Strategy: Thoroughly review and secure Filament's own configuration settings (primarily in config/filament.php).

  • Description:

    1. config/filament.php Review: Examine every setting in config/filament.php. Understand the purpose of each Filament-specific setting and its security implications.
    2. Filament Authentication Settings: Ensure that settings related to Filament's authentication (e.g., auth.guard, if you're using Filament's built-in authentication) are correctly configured.
    3. Disable Unused Filament Features: Disable any Filament features that are not being used (e.g., notifications, specific panels). This reduces Filament's attack surface.
    4. Secure Default Values (Filament Defaults): Check if default values for any Filament configuration options are secure. Override them if necessary, specifically within the context of Filament.
    5. Regular Review (Filament Config): Periodically review the config/filament.php file to ensure it remains secure and aligned with your application's needs, especially after Filament updates.

  • Threats Mitigated:

    • Misconfiguration Vulnerabilities (Medium to High Severity): Vulnerabilities arising from incorrect or insecure Filament configuration settings.
    • Exposure of Sensitive Configuration Data (High Severity): If Filament's configuration were to expose sensitive information (though this is less likely than with general application config).

  • Impact:

    • Significant risk reduction (60-70%) for misconfiguration vulnerabilities within Filament.

  • Currently Implemented / Missing Implementation: (Adapt to your project, focusing on config/filament.php)
