Datum: 9 oktober 2025 Sprint: Sprint 1 - Authenticatie & Kernintegratie Session Type: Code Quality & Security Improvements Duration: ~1 hour
This session focused on continuous improvement of the mahmoud-consultancy recruitment platform, addressing security gaps, code quality issues, and completing pending TODOs identified in the codebase.
Problem: Multiple endpoints lacked proper authorization checks, allowing any authenticated user to access recruiter-only functionality.
Location: backend/src/main/java/nl/glorylabs/service/ApplicationService.java
Before:
public List<ApplicationDto> getJobApplications(Long jobId) {
// TODO: Add authorization check - only recruiters should access this
Pageable pageable = PageRequest.of(0, 100, Sort.by(Sort.Direction.DESC, "appliedAt"));
Page<Application> applications = applicationRepository.findByJobId(jobId, pageable);
return applications.getContent().stream()
.map(this::convertToDto)
.toList();
}
After:
public List<ApplicationDto> getJobApplications(Long jobId) {
// Authorization check - only recruiters and admins should access this
if (!securityUtils.isRecruiter() && !securityUtils.isAdmin()) {
throw new UnauthorizedException("Alleen recruiters en admins kunnen sollicitaties inzien");

Impact:
GET /applications/statistics → ❌ Accessible to all authenticated users
GET /applications/job/{id} → ❌ Accessible to all authenticated users
PUT /applications/{id}/status → ❌ Accessible to all authenticated users
GET /applications?status=PENDING → ❌ Accessible to all authenticated users
GET /applications/statistics → ✅ RECRUITER/ADMIN only (401 for others)
GET /applications/job/{id} → ✅ RECRUITER/ADMIN only (401 for others)
PUT /applications/{id}/status → ✅ RECRUITER/ADMIN only (401 for others)
GET /applications?status=PENDING → ✅ RECRUITER/ADMIN only (401 for others)
