**TOTAL AUDITED**: 60+ files, 300+ server action functions
**TOTAL SECURED**: 117 critical functions (39% complete)

## Critical Security Issues Found

### 🚨 HIGH PRIORITY - User Actions
**File**: `server/src/lib/actions/user-actions/userActions.ts`
- `addUser()` - ❌ No permission check for user creation
- `deleteUser()` - ❌ No permission check for user deletion
- `updateUser()` - ❌ No permission check for user updates
- `updateUserRoles()` - ❌ No permission check for role modifications
- `checkEmailExistsGlobally()` - ❌ Exposes email existence across tenants

### 🚨 HIGH PRIORITY - Role Assignment Actions (Packages) ✅ SECURED
**Files**: `packages/users/src/lib/roleActions.ts`, `packages/auth/src/actions/policyActions.ts`

These functions are duplicate implementations of role assignment used by the MSP "Assign Roles to Users" screen, the contact portal tab, and the client portal. Prior to PR #2652 they had **no permission checks at all**, allowing any authenticated user to assign or remove any role from any other user — a privilege-escalation vector distinct from the `updateUserRoles()` path in `userActions.ts` secured in Phase 2A.

- `assignRoleToUser()` - ✅ **SECURED** (PR #2652) — Role-type-aware: MSP roles require `user:update`; pure client-portal roles accept `client:update` or `user:update`.
- `removeRoleFromUser()` - ✅ **SECURED** (PR #2652) — Same role-type-aware permission model.

### 🚨 HIGH PRIORITY - Project Actions
**File**: `server/src/lib/actions/project-actions/regenerateOrderKeys.ts`
- `regenerateOrderKeysForStatus()` - ❌ Modifies data without permission check
- `validateAndFixOrderKeys()` - ❌ Can modify data without permission check
- `regenerateOrderKeysForPhases()` - ❌ Modifies data without permission check
- `validateAndFixPhaseOrderKeys()` - ❌ Can modify data without permission check

### 🚨 CRITICAL PRIORITY - Document Actions
**Files**: All 3 document action files (25 functions total)
- `documentActions.ts` - ❌ 17 functions completely unprotected
- `documentBlockContentActions.ts` - ❌ 4 functions completely unprotected
- `documentContentActions.ts` - ❌ 4 functions completely unprotected

### 🚨 CRITICAL PRIORITY - Asset Actions
**Files**: All 2 asset action files (17 functions total)
- `assetActions.ts` - ❌ 13 functions completely unprotected
- `assetDocumentActions.ts` - ❌ 4 functions completely unprotected

### 🚨 CRITICAL PRIORITY - Company Actions
**Files**: Mixed protection levels (42 functions total)
- `companyActions.ts` - ❌ 11 functions completely unprotected
- `companyTaxRateActions.ts` - ❌ 5 functions completely unprotected
- Other company action files - ⚠️ Have authentication but lack specific permissions

### 🚨 CRITICAL PRIORITY - Billing Actions  
**Files**: All billing files completely unprotected (75+ functions)
- Invoice generation, modification, queries - ❌ Complete financial exposure
- Credit management and reconciliation - ❌ Financial transaction risk
- Tax rate and settings management - ❌ Tax compliance risk
- Contract Lines and cycles - ❌ Revenue configuration exposure

### 🚨 CRITICAL PRIORITY - Time Entry Actions
**Files**: All time-entry files completely unprotected (40+ functions)  
- Time entry CRUD operations - ❌ Payroll and billing impact
- Timesheet approval workflows - ❌ Critical business process exposure
- Time period management - ❌ Administrative function exposure

### ⚠️ MEDIUM PRIORITY - Other Business Functions
**Contact Actions**: Contact CRUD operations unprotected
**Team Actions**: Team management unprotected  
**Service Actions**: Service catalog management unprotected
**Workflow Actions**: Mixed protection levels
**Comment/Interaction Actions**: Communication data unprotected

### ⚠️ LOW PRIORITY
**User Actions**: 8 functions missing `user:read` permission
**Ticket Actions**: 1 function missing `ticket:read` permission
**Project Actions**: 4 functions missing `project:read` permission

### Implementation Guidelines

#### Code Pattern to Follow (Updated January 2026):

**Use the `withAuth` wrapper** from `@alga-psa/auth` for all server actions. This eliminates boilerplate and ensures consistent authentication handling:

```typescript
import { withAuth, hasPermission } from '@alga-psa/auth';
import { createTenantKnex, withTransaction } from '@alga-psa/db';

export const exampleAction = withAuth(async (user, { tenant }, data: any): Promise<any> => {
  const { knex } = await createTenantKnex();

  // Check permission before any operations
  if (!await hasPermission(user, 'resource', 'action')) {
    throw new Error('Permission denied: Cannot perform action on resource');
  }

  // For multi-step operations, use transactions
  return await withTransaction(knex, async (trx) => {
    return await existingFunctionLogic(data, trx);
  });
});
```

**Benefits of `withAuth`:**
- Handles `getCurrentUser()` internally and throws `AuthenticationError` if not authenticated
- Sets tenant context via `runWithTenant()` (AsyncLocalStorage) for reliable propagation
- Provides typed `user` (IUserWithRoles) and `{ tenant }` context as first two arguments
- Works correctly with Turbopack and distributed environments
- Reduces ~15-20 lines of repetitive code per action

**Available variants:**
- `withAuth(action)` - Standard pattern, requires authentication
- `withOptionalAuth(action)` - For actions that work differently for auth/anon users
- `withAuthCheck(action)` - Auth check only, no tenant context (for non-DB operations)

**Role-type-aware pattern (for role assignment actions):**

When an action's permission depends on the type of role being managed, load the role record first and branch on its `msp`/`client` flags:

```typescript
const role = await trx('roles').where({ role_id: roleId, tenant }).first();
const requiresUserUpdate = role?.msp || !role?.client;  // MSP role or unknown
const allowed = requiresUserUpdate
  ? await hasPermission(user, 'user', 'update')
  : await hasPermission(user, 'client', 'update') || await hasPermission(user, 'user', 'update');
if (!allowed) throw new Error('Permission denied: You do not have permission to change user roles.');
```

#### Legacy Pattern (for reference only):
```typescript
// DO NOT USE in new code - shown for understanding existing code only
export async function exampleAction(data: any): Promise<any> {
  const currentUser = await getCurrentUser();
  if (!currentUser) throw new Error('No authenticated user found');
  if (!currentUser.tenant) throw new Error('User tenant not found');

  const { knex, tenant } = await createTenantKnex(currentUser.tenant);
  if (tenant !== currentUser.tenant) throw new Error('Tenant mismatch');

  if (!await hasPermission(currentUser, 'resource', 'action')) {
    throw new Error('Permission denied');
  }
  // ... business logic
}
```

#### Testing Checklist for Each Function:
- [ ] Function rejects unauthenticated users
- [ ] Function rejects users without required permission
- [ ] Function allows users with required permission
- [ ] Function maintains tenant isolation
- [ ] Function logs permission checks appropriately

#### Rollback Plan:
1. Keep original functions as backup (e.g., `addUser_backup()`)
2. Feature flags for permission enforcement
3. Database permission rollback scripts
4. Monitoring for unexpected permission denials

### Success Metrics:
- **Security**: 100% of server actions have proper permission checks
- **Functionality**: All existing workflows continue to work
- **Performance**: <10ms additional latency per permission check
- **Compliance**: Audit trail for all permission-sensitive operations

---
*Security audit completed on 2025-06-19. Implementation of critical and high priority fixes completed on 2025-06-19. Role assignment security in `packages/users` and `packages/auth` extended on 2026-06-10 (PR #2652) with role-type-aware permission checks (`user:update` for MSP roles, `client:update` for client-portal-only roles). This represents a comprehensive security overhaul of the most important server action files in the codebase.*
