 ### 1.5 Input Validation
 
-#### DBAL-2025-010: ReDoS in Email Validation (LOW)
+#### DBAL-2025-010: ReDoS in Email Validation (LOW → MEDIUM)
 **Location**: Validation functions in [validation/](../ts/src/core/validation/)
 
 **Risk**:
 - Complex regex patterns in email/username validation could be vulnerable to ReDoS
 - Pattern: CWE-1333 (Inefficient Regular Expression Complexity)
+- Attacker can craft input that causes exponential backtracking
 
-**Recommendation**:
-- Audit all regex patterns with tools like `safe-regex`
-- Set validation timeout limits
-- Use linear-time validation libraries

+### 5.3 Penetration Test Checklist
+
+```markdown
+## DBAL Penetration Test Checklist
+
+### Authentication & Session Management
+- [ ] Test for authentication bypass
+- [ ] Verify session tokens have sufficient entropy
+- [ ] Check for session fixation vulnerabilities
+- [ ] Test token expiration enforcement
+- [ ] Verify secure cookie flags (HttpOnly, Secure, SameSite)
+
+### Authorization
+- [ ] Test horizontal privilege escalation (tenant A accessing tenant B)
+- [ ] Test vertical privilege escalation (user to admin)
+- [ ] Verify IDOR protection on all endpoints
+- [ ] Test for missing function-level access control
+
+### Injection
+- [ ] SQL injection on all inputs
+- [ ] NoSQL injection (if applicable)
+- [ ] Command injection
+- [ ] LDAP injection (if applicable)
+- [ ] Path traversal on all file operations
+- [ ] Server-side template injection
+
+### Data Validation
+- [ ] Test with null bytes in strings
+- [ ] Test with Unicode normalization attacks
+- [ ] Test integer overflow/underflow
+- [ ] Test with extremely long inputs
+- [ ] Test with malformed JSON/XML
+
+### Business Logic
+- [ ] Test quota bypass via race conditions
+- [ ] Test for price manipulation
+- [ ] Test workflow bypass
+- [ ] Test for mass assignment
+
+### Cryptography
+- [ ] Verify TLS configuration (TLS 1.3 only)
+- [ ] Check for weak cipher suites
+- [ ] Verify certificate pinning
+- [ ] Test for timing attacks on comparisons
