: Use consistent dependency injectionCurrently,
cookieUtil
andjwtUtil
are injected both via field injection (@Autowired
on fields) and a constructor.Choose one injection method for consistency. Prefer constructor injection for mandatory dependencies.
Apply this diff to modify to constructor injection:
- @Autowired - private CookieUtil cookieUtil; - @Autowired - private JwtUtil jwtUtil; + private final CookieUtil cookieUtil; + private final JwtUtil jwtUtil; private final Logger logger = LoggerFactory.getLogger(this.getClass().getName()); - @Autowired private GenerateBeneficiaryService generateBeneficiaryService; - public JwtAuthenticationUtil(CookieUtil cookieUtil, JwtUtil jwtUtil) { + @Autowired + public JwtAuthenticationUtil(CookieUtil cookieUtil, JwtUtil jwtUtil, GenerateBeneficiaryService generateBeneficiaryService) { this.cookieUtil = cookieUtil; this.jwtUtil = jwtUtil; + this.generateBeneficiaryService = generateBeneficiaryService; }src/main/java/com/iemr/common/bengen/utils/JwtUserIdValidationFilter.java (2)

: Optimize retrieval of JWT token from cookiesThe method
getJwtTokenFromCookies
can be optimized using streams for better readability.Consider refactoring as:
private String getJwtTokenFromCookies(HttpServletRequest request) { if (request.getCookies() != null) { return Arrays.stream(request.getCookies()) .filter(cookie -> "Jwttoken".equals(cookie.getName())) .map(Cookie::getValue) .findFirst() .orElse(null); } return null; }src/main/java/com/iemr/common/bengen/repo/UserRepository.java (1)

: Clarify the usage of insertable = false
on the deleted
field
Setting insertable = false
means that the deleted
field won't be included in SQL INSERT statements.
Ensure that this behavior is intentional.
Run the following script to check for annotations on the deleted
field:
β Verification successful
Let me gather more context about the deleted
field usage and initialization.
Let me try a different approach to understand the User class and its deleted field usage.
Setting insertable = false
on deleted
field appears to be a database-driven soft delete pattern
The deleted
field configuration in the User entity suggests a common soft delete pattern where:
- The database column "Deleted" likely has a DEFAULT value set to false
- The field is excluded from INSERT statements (
insertable = false
) - But can be updated later for soft deletion (
updatable = true
)
This is a standard and safe implementation for soft delete functionality where:
- New users are always created with
deleted = false
through the database default - The field can be updated to
true
when performing soft deletes - The JPA entity respects the database default by not including this field in inserts

Ensure secure handling of JWT tokens and avoid sensitive information leakage
In the validateJwtToken
method:
- Security Concerns:
- Storing JWT tokens in cookies can expose the application to cross-site scripting (XSS) attacks. Ensure that cookies are marked with
HttpOnly
andSecure
flags to mitigate this risk. - Returning detailed error messages like "Error 401: Unauthorized - JWT Token is not set!" can provide useful information to attackers. Consider using generic error messages for clients and logging detailed messages on the server side.
- Storing JWT tokens in cookies can expose the application to cross-site scripting (XSS) attacks. Ensure that cookies are marked with

π οΈ Refactor suggestion
Avoid catching and throwing generic Exception
Catching and throwing the generic Exception
can obscure the real cause of errors and make debugging difficult.
Refactor to catch specific exceptions and consider creating custom exception classes for better error handling.
Apply this diff to improve exception handling:
-} catch (Exception e) {
+} catch (NumberFormatException e) {
+ logger.error("User ID format is invalid: " + e.getMessage(), e);
+ throw new ValidationException("Invalid User ID format.", e);
+} catch (JwtException e) {
+ logger.error("JWT validation failed: " + e.getMessage(), e);
+ throw new ValidationException("Invalid JWT token.", e);
+} catch (Exception e) {
logger.error("Validation failed: " + e.getMessage(), e);
- throw new Exception("Validation error: " + e.getMessage(), e);
+ throw new ValidationException("Validation error: " + e.getMessage(), e);
}
Ensure that ValidationException
is a custom exception that appropriately represents validation errors.

π‘ Codebase verification
Strengthen JWT secret configuration and validation
Based on the code analysis:
- The JWT implementation uses HMAC-SHA256 (HS256) which requires at least a 256-bit (32-byte) secret key
- The current properties files have empty JWT secrets (
jwt.secret=
) - The code has basic validation for null/empty secrets but no length or complexity validation
- The secret is directly used as bytes without proper Base64 decoding
Action items:
- Ensure the
JWT_SECRET_KEY
environment variable is set with a Base64-encoded random key of at least 32 bytes - Update
JwtUtil.getSigningKey()
to decode the Base64 secret before using it - Add validation for minimum secret length and proper Base64 format
- Configure non-empty secrets in all environment property files
π Analysis chain
Ensure JWT secret meets security requirements
While using environment variables for JWT secrets is a good practice, please ensure that:
- The secret key is at least 256 bits (32 characters) long
- The secret is randomly generated using a cryptographically secure method
- Different secrets are used for different environments
Let's verify the JWT secret configuration:
Let me gather more information about the JWT configuration and usage in the codebase.
Let me check the JWT implementation to understand how the secret is being used.
Let me check the token generation implementation to understand how the secret is being used.

π‘ Codebase verification
JWT implementation requires security improvements
The verification revealed several security concerns that need to be addressed:
- Token validation in
JwtUtil.java
returns null on validation failure instead of throwing specific exceptions, which could lead to silent failures - No CSRF protection was found in the codebase
- JWT token expiration is implemented but error handling for expired tokens needs improvement
- The signing key mechanism needs review as it's not visible in the current implementation
Required changes:
- Implement proper exception handling for JWT validation failures (expired, malformed, invalid signature)
- Add CSRF protection mechanism
- Enhance error responses with specific status codes and messages for different token validation scenarios
- Review and secure the signing key management
π Analysis chain
Verify complete JWT implementation security
Please ensure the following security aspects are properly implemented:
- JWT token expiration
- Token signature verification
- CSRF protection
- Proper error responses for invalid tokens

Add validation for minimum secret key length
While the method checks for null/empty secret key, it should also validate the minimum length to ensure adequate security. HMAC-SHA256 requires at least 256 bits (32 bytes) of key material for optimal security.

if (SECRET_KEY == null || SECRET_KEY.isEmpty()) {

Improve token validation error handling
The current implementation returns null for all validation failures, making it difficult to handle specific error cases (expired token, invalid signature, etc.). Consider throwing specific exceptions or returning a validation result object.

:β οΈ Potential issueEnhance security measures for JWT handling
The current implementation has several security concerns:
- Detailed error messages could aid attackers in understanding the system
- No visible CSRF protection for cookie handling
- Cookie security attributes not specified
Apply this diff to implement more secure error handling:
if (jwtTokenOpt.isEmpty()) { return ResponseEntity.status(HttpStatus.UNAUTHORIZED) - .body("Error 401: Unauthorized - JWT Token is not set!"); + .body("Authentication failed"); } String jwtToken = jwtTokenOpt.get(); // Validate the token Claims claims = jwtUtil.validateToken(jwtToken); if (claims == null) { return ResponseEntity.status(HttpStatus.UNAUTHORIZED) - .body("Error 401: Unauthorized - Invalid JWT Token!"); + .body("Authentication failed"); } // Extract username from token String usernameFromToken = claims.getSubject(); if (usernameFromToken == null || usernameFromToken.isEmpty()) { return ResponseEntity.status(HttpStatus.UNAUTHORIZED) - .body("Error 401: Unauthorized - Username is missing!"); + .body("Authentication failed"); }Additionally:
- Ensure
CookieUtil
sets appropriate security attributes (HttpOnly, Secure, SameSite)- Implement CSRF protection
- Consider adding rate limiting for this endpoint

:β οΈ Potential issueImprove validation and exception handling
The current implementation needs several improvements:
- Missing null check for userId
- Generic exception handling masks specific issues
- No token expiration validation

public class JwtValidationException extends Exception { public JwtValidationException(String message) { super(message); } } public class UserNotFoundException extends Exception { public UserNotFoundException(String message) { super(message); } } public class AuthenticationException extends Exception { public AuthenticationException(String message, Throwable cause) { super(message, cause); } }

Add essential fields for JWT authentication and security
The User entity is missing crucial fields needed for JWT authentication and security audit. Consider adding:
- Password/credentials field (hashed)
- Audit fields (createdAt, modifiedAt)
- Version field for optimistic locking
- Role/permissions for JWT claims
Would you like me to provide a complete implementation with these security enhancements?

π‘ Codebase verification
Redis security configuration needs improvement
The Redis configuration has critical security gaps:
- Empty password configuration (
spring.redis.password=
) - No SSL/TLS configuration
- Default port (6379) is exposed
- Host configuration is commented out
Action items:
- Configure a strong Redis password
- Enable SSL/TLS for encrypted communication
- Consider using a non-default port
- Ensure host configuration is properly set
π Analysis chain
Verify Redis security configuration
Using ConfigureRedisAction.NO_OP
bypasses Redis configuration commands. Ensure Redis server is properly secured:
- Password authentication
- SSL/TLS encryption
- Network security
Let's check the content of the application.properties file to verify the Redis security configuration.
π Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Check if Redis security properties are defined
rg -l "spring\.redis\.(password|ssl|sentinel)"
