Remove deprecated connection options that are no longer needed in Mongoose 6+: - useNewUrlParser - useUnifiedTopology - useCreateIndex - useFindAndModify These options are now defaults and cause warnings in newer versions. Affects: - backend/server.js: Remove options from main DB connection - backend/setup-test.js: Remove mongoose.set() and connection options - backend/scripts/cloneOrSyncCollections.js: Keep dbName, remove deprecated options Related to Mongoose upgrade from 5.x to 8.x for CVE-2024-53900 fix.
Convert callback-based Mongoose API calls to async/await pattern, required for Mongoose 7+ which dropped callback support. Changes: - backend/server.js: Convert initial() function to async/await - estimatedDocumentCount() callback → await - Role.save() callbacks → await - Call initial() after runServer() connection completes - backend/controllers/user.controller.js: Convert UserController.createUser() - user.save() callback → try/catch with await This ensures compatibility with Mongoose 7+ which removed all callback support in favor of promises. Related to Mongoose upgrade from 5.x to 8.x for CVE-2024-53900 fix.
Add 'new' keyword to ObjectId() calls to comply with Mongoose 7+ stricter constructor requirements. MongoDB driver ObjectId constructor requires 'new' keyword in newer versions. Changes: - backend/controllers/user.controller.js: Add 'new' to 3 ObjectId calls in bulkUpdateManagedProjects() function - backend/controllers/project.controller.js: Add 'new' to 3 ObjectId calls in bulkUpdateManagedByUsers() function Without 'new' keyword, ObjectId constructor may throw errors or behave unexpectedly in Mongoose 8 with MongoDB driver v6. Related to Mongoose upgrade from 5.x to 8.x for CVE-2024-53900 fix.
Upgrade Mongoose to address critical security vulnerabilities: - CVE-2024-53900 (CVSS 8.7): Search injection vulnerability allowing arbitrary JavaScript execution via $where operator - CVE-2025-23061: Incomplete fix bypass for CVE-2024-53900 Mongoose 8.9.5 includes complete patches for both vulnerabilities. Breaking changes handled in previous commits: - Removed deprecated connection options - Converted callbacks to async/await - Added 'new' keyword to ObjectId constructors Minimum Mongoose versions with CVE fixes: 6.13.5, 7.8.3, 8.8.3 This upgrade uses 8.9.5 for complete protection. BREAKING CHANGE: Requires Node.js 16+
