# Customer Portal Changelog
|
||
|
|
|
||
|
|
## 🎯 **Implementation Status: COMPLETE**
|
||
|
|
|
||
|
|
All critical issues identified in the codebase audit have been successfully resolved. The system is now production-ready with significantly improved security, reliability, and performance.
|
||
|
|
|
||
|
|
## 🔴 **Critical Security Fixes**
|
||
|
|
|
||
|
|
### **Refresh Token Bypass Vulnerability** ✅ **FIXED**
|
||
|
|
- **Issue**: System bypassed security during Redis outages, enabling replay attacks
|
||
|
|
- **Solution**: Implemented fail-closed pattern - system now fails securely when Redis unavailable
|
||
|
|
- **Impact**: Eliminated critical security vulnerability
|
||
|
|
|
||
|
|
### **WHMCS Orphan Accounts** ✅ **FIXED**
|
||
|
|
- **Issue**: Failed user creation left orphaned billing accounts
|
||
|
|
- **Solution**: Implemented compensation pattern with proper transaction handling
|
||
|
|
- **Impact**: No more orphaned accounts, proper cleanup on failures
|
||
|
|
|
||
|
|
## 🟡 **Performance & Reliability Improvements**
|
||
|
|
|
||
|
|
### **Salesforce Authentication Timeouts** ✅ **FIXED**
|
||
|
|
- **Issue**: Fetch calls could hang indefinitely
|
||
|
|
- **Solution**: Added AbortController with configurable timeouts
|
||
|
|
- **Impact**: No more hanging requests, configurable timeout protection
|
||
|
|
|
||
|
|
### **Logout Performance Issue** ✅ **FIXED**
|
||
|
|
- **Issue**: O(N) Redis keyspace scans on every logout
|
||
|
|
- **Solution**: Per-user token sets for O(1) operations
|
||
|
|
- **Impact**: Massive performance improvement for logout operations
|
||
|
|
|
||
|
|
### **Docker Build References** ✅ **FIXED**
|
||
|
|
- **Issue**: Dockerfiles referenced non-existent `packages/shared`
|
||
|
|
- **Solution**: Updated Dockerfile and ESLint config to reference only existing packages
|
||
|
|
- **Impact**: Docker builds now succeed without errors
|
||
|
|
|
||
|
|
