# Bug Report - Comprehensive Code Audit
**Date:** 2025-01-27
**Scope:** Full codebase security and functionality audit
---
## 🔴 CRITICAL SECURITY ISSUES
### 1. **Hardcoded Database Credentials**
**Location:** `config/database.php` lines 41-44
**Issue:** Database credentials are hardcoded in the source code as fallback values.
```41:44:config/database.php
define('DB_HOST', 'localhost');
define('DB_NAME', 'gositeme_soundstudiopro');
define('DB_USER', 'gositeme_soundstudiopro');
define('DB_PASS', 'ttkKaHQunYYwgLCn6GxZ');
```
**Risk:** HIGH - If source code is exposed (GitHub, backups, etc.), database credentials are compromised.
**Recommendation:**
- Remove hardcoded credentials completely
- Force use of environment variables or external config file
- Add `.htaccess` protection for `database.env.php` if using external config
---
### 2. **Admin Authentication Bypass**
**Location:** `admin_debug.php` lines 4-8
**Issue:** Admin authentication check is commented out, allowing unauthorized access to admin debug functionality.
```4:8:admin_debug.php
// Temporarily bypass admin check for debugging
// if (!isset($_SESSION['user_id']) || !isset($_SESSION['is_admin']) || !$_SESSION['is_admin']) {
// header('Location: /auth/login.php');
// exit;
// }
```
**Risk:** HIGH - Anyone can access admin debug page and view sensitive database information.
**Recommendation:**
- Remove or properly secure this file
- If needed for debugging, add IP whitelist or remove from production
- Never commit debug files with authentication bypasses
---
### 3. **SSL Verification Disabled**
**Location:** `callback.php` line 341
**Issue:** cURL SSL verification is disabled when downloading images.
```341:341:callback.php
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
```
**Risk:** MEDIUM - Vulnerable to man-in-the-middle attacks when downloading external images.
**Recommendation:**
- Enable SSL verification: `curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, true);`
- If needed, specify CA bundle path instead of disabling verification
---
## 🟡 HIGH PRIORITY BUGS
### 4. **Missing Image URL for Main Track**
**Location:** `callback.php` (documented in `COMPREHENSIVE_BUG_AUDIT.md`)
**Issue:** Variations save `image_url`, but the main track never saves its `image_url` from the API response.
**Impact:** Users can't see cover images for their tracks, only variations have images.
**Status:** Documented but not fixed
---
### 5. **Task ID Not Updated on API Failure**
**Location:** `create_music.php`, `create_track_extension.php`, etc.
**Issue:** When API call fails, tracks remain with `temp_task_id` and are never updated. Callbacks can't find the track.
**Impact:** Failed API calls leave tracks in unrecoverable state.
**Status:** Documented in `COMPREHENSIVE_BUG_AUDIT.md` but not fixed
---
### 6. **Inconsistent Field Extraction in Callbacks**
**Location:** `callback.php` (documented in `ADDITIONAL_BUGS_AUDIT.md`)
**Issues:**
- Duration not extracted in `task_id` and `id` callback formats
- Tags not extracted in `task_id` and `id` callback formats
- Model name not saved as direct field
- Duration not extracted in early callbacks (text, first)
**Impact:** Missing metadata depending on which callback format is received.
**Status:** Documented but not fixed
---
## 🟢 MEDIUM PRIORITY ISSUES
### 7. **No Validation on Task ID Updates**
**Location:** All files that update task_id
**Issue:** Task IDs are updated without validation. Invalid task_id (empty string, null, or same as temp_task_id) still gets saved.
**Impact:** Invalid task_ids could break callback matching.
**Recommendation:**
- Validate task_id before updating (not empty, not null, different from temp_task_id)
- Only update if task_id is valid
- Log when task_id update is skipped due to validation
---
### 8. **Race Condition in Callback Processing**
**Location:** `callback.php`
**Issue:** Multiple callbacks for the same task_id could arrive simultaneously, causing race conditions when updating the same track.
**Impact:** Could lead to data corruption or lost updates if multiple callbacks arrive at once.
**Recommendation:**
- Use database transactions with row-level locking
- Check if track is already complete before updating
- Use optimistic locking with version numbers
---
### 9. **Missing Error Status Updates on API Failure**
**Location:** `create_music.php`, `create_track_extension.php`, etc.
**Issue:** When API call fails, tracks remain in 'processing' status instead of being marked as 'failed'.
**Impact:** Users see tracks stuck in processing state indefinitely.
**Recommendation:**
- Update track status to 'failed' on API errors
- Store error message in error_details field
- Notify user of failure
---
### 10. **Potential XSS Vulnerabilities**
**Location:** Multiple files using `echo` with user data
**Issue:** While many places use `htmlspecialchars()`, there are 4938 instances of `echo` with variables. Need to verify all user inputs are properly escaped.
**Recommendation:**
- Audit all `echo` statements for proper escaping
- Create helper function for safe output: `function safeEcho($text) { echo htmlspecialchars($text, ENT_QUOTES, 'UTF-8'); }`
- Use Content Security Policy headers
---
## 🔵 LOW PRIORITY / CODE QUALITY ISSUES
### 11. **Inconsistent Error Handling**
**Location:** Throughout codebase
**Issue:** Error handling patterns vary across files. Some use try-catch, some use error_log, some return false.
**Recommendation:**
- Standardize error handling with centralized error handler
- Use consistent logging format
- Implement proper error responses for API endpoints
---
### 12. **Duplicate Code Files**
**Location:** Root directory
**Issue:** Multiple backup/duplicate files found:
- `checkout copy 2.php`, `checkout_broken.php`, `checkout.php.old`, `checkout.php.backup`
- `event_details_backup.php`, `event_details_broken.php`, `event_details_fixed.php`, etc.
- `library copy.php`, `library_fixed.php`, `library_modern.php`, etc.
**Recommendation:**
- Remove or archive old backup files
- Use version control (Git) instead of file copies
- Clean up root directory
---
### 13. **Debug Files in Production**
**Location:** Multiple files
**Issue:** Debug/test files present in production:
- `admin_debug.php`
- `force_stephane_session.php`
- `check_user_names.php`
- `test_*.php` files
**Recommendation:**
- Remove debug files from production
- Use environment-based debugging
- Move test files to separate directory excluded from web root
---
### 14. **Missing Input Validation**
**Location:** Various form handlers
**Issue:** Some form inputs lack proper validation (length, format, type).
**Recommendation:**
- Add server-side validation for all inputs
- Validate file uploads (type, size, content)
- Sanitize all user inputs before database operations
---
### 15. **No Rate Limiting**
**Location:** API endpoints
**Issue:** No rate limiting on API endpoints, allowing potential abuse.
**Recommendation:**
- Implement rate limiting per IP/user
- Add throttling for expensive operations
- Log suspicious activity

## 📝 NOTES
- Most SQL queries use prepared statements (good!)
- Most output uses `htmlspecialchars()` (good!)
- Database connection uses PDO with proper error handling (good!)
- Many bugs are already documented in audit files but not yet fixed
- Codebase appears to be actively maintained with recent fixes
