1 # Security Audit - Desktop Downloads Feature
2
3 ## 🔒 Security Review Date: 2024
4
5 **Status**: ✅ **PASSED** - No credential leaks detected
6
7 ## Overview
8
9 This document provides a comprehensive security audit of the desktop downloads feature implementation, with special focus on credential protection since this repository is **PUBLIC**.
10
11 ## ⚠️ Important Notice
12
13 **This repository (pepakbasajawa-web) is PUBLIC.**
14 All security measures must assume that any code committed here is visible to everyone.
15
16 ## 🔍 Audit Findings
17
18 ### ✅ PASS: Environment Variables
19
20 **Location**: `.env`, `.env.production`
21
22 **Status**: PROTECTED
23 - ✅ `.env` is in `.gitignore`
24 - ✅ `.env.production` is in `.gitignore`
25 - ✅ No `.env` files committed to repository
26 - ✅ Verified with: `git ls-files | grep .env` (returns empty)
27
28 **Evidence**:
29 ```
30 # From .gitignore:
31 .env
32 .env.production
33 ```
34
35 ### ✅ PASS: No Hardcoded Credentials
36
37 **Locations Checked**: All `*.ts`, `*.js`, `*.astro` files
38
39 **Status**: CLEAN
40 - ✅ No actual GitHub tokens in code
41 - ✅ No API keys hardcoded
42 - ✅ All credentials loaded from `import.meta.env` or `process.env`
43
44 **Code Review**:
45 ```typescript
46 // CORRECT: Token loaded from environment
47 const GITHUB_TOKEN = import.meta.env.GITHUB_TOKEN
48
49 // NEVER do this:
50 // const GITHUB_TOKEN = "ghp_actual_token_here" ❌
51 ```
52
53 ### ✅ PASS: API Endpoint Security
54
55 **Location**: `src/pages/api/download-desktop-app.ts`
56
57 **Status**: SECURE
58
59 **Security Measures**:
60 1. ✅ Token never included in response
61 2. ✅ Token only used server-side
62 3. ✅ Token sent to GitHub via Authorization header
63 4. ✅ No token logging in production
64 5. ✅ Error messages don't leak token
65 6. ✅ Downloads proxied through server (token not exposed to client)
66
67 **Response Example** (Safe):
68 ```json
69 {
70 "version": "v1.0.0",
71 "downloads": [
72 {
73 "url": "/api/download-desktop-app?action=download&assetId=12345"
74 }
75 ]
76 }
77 ```
78 Note: Asset ID is public (from GitHub), not sensitive.
79
80 ### ✅ PASS: Documentation
81
82 **Locations**: `*.md` files
83
84 **Status**: SAFE
85 - ✅ Only placeholder tokens used (`ghp_your_token_here`)
86 - ✅ Clear instructions to NOT commit tokens
87 - ✅ No actual tokens in examples
88
89 **Example Placeholders Used**:
90 - `ghp_your_token_here` ✅
91 - `ghp_your_actual_token_here` ✅
92 - `your_token_here` ✅
93
94 ### ✅ PASS: Test Scripts
95
96 **Location**: `scripts/test-github-releases.js`
97
98 **Status**: SECURE
99 - ✅ Reads token from environment only
100 - ✅ Truncates token in output (`ghp_abcd12...`)
101 - ✅ No token logging in normal operation
102
103 **Safe Output Example**:
104 ```
105 ✓ GitHub token found (ghp_abcd12...)
106 ```
107
108 ### ✅ PASS: Client-Side Code
109
110 **Location**: `src/pages/download.astro`
111
112 **Status**: SECURE
113 - ✅ No token access on client side
114 - ✅ Only calls public API endpoint
115 - ✅ JavaScript runs in browser (no server secrets)
116
117 ## 🛡️ Security Measures Implemented
118
119 ### 1. Environment Variable Protection
120
121 ```bash
122 # .gitignore ensures these are NEVER committed:
123 .env
124 .env.production
125 ```
126
127 ### 2. Server-Side Token Usage
128
129 ```typescript
130 // Token only used in server-side API routes
131 export const prerender = false // Ensures server-side execution
132 const GITHUB_TOKEN = import.meta.env.GITHUB_TOKEN // Server env only
133 ```
134
135 ### 3. Token Validation
136
137 ```typescript
138 if (!GITHUB_TOKEN) {
139 console.error('GITHUB_TOKEN is not configured')
140 return new Response(JSON.stringify({ error: 'Server configuration error' }), {
141 status: 500
142 })
143 }
144 ```
145
146 ### 4. Secure Token Transmission
147
148 ```typescript
149 // Token sent only to GitHub, never to client
150 headers: {
151 Authorization: `Bearer ${GITHUB_TOKEN}`,
152 Accept: 'application/vnd.github+json'
153 }
154 ```
155
156 ### 5. Download Proxying
157
158 ```typescript
159 // Client requests: /api/download-desktop-app?action=download&assetId=123
160 // Server authenticates with GitHub
161 // GitHub returns temporary redirect URL
162 // Client downloads file (no token exposure)
163 ```
164
165 ## 🚨 What Could Go Wrong (And Prevention)
166
167 ### Risk 1: Accidentally Committing .env
168
169 **Prevention**:
170 - ✅ `.env` in `.gitignore`
171 - ✅ `.env.example` provided instead (no real tokens)
172 - ✅ Documentation warns about this
173
174 **If It Happens**:
175 ```bash
176 # Immediately revoke the token at:
177 # https://github.com/settings/tokens
178
179 # Remove from git history:
180 git filter-branch --force --index-filter \
181 "git rm --cached --ignore-unmatch .env" \
182 --prune-empty --tag-name-filter cat -- --all
183
184 # Force push (careful!):
185 git push origin --force --all
186 ```
187
188 ### Risk 2: Token in Logs
189
190 **Prevention**:
191 - ✅ No token logging in production code
192 - ✅ Test script truncates token output
193 - ✅ Error messages don't include token
194
195 **Safe Logging**:
196 ```javascript
197 // DO this:
198 log(`✓ GitHub token found (${GITHUB_TOKEN.substring(0, 10)}...)`)
199
200 // DON'T do this:
201 log(`Token: ${GITHUB_TOKEN}`) // ❌
202 ```
203
204 ### Risk 3: Token in Client-Side Code
205
206 **Prevention**:
207 - ✅ API routes marked as `prerender = false` (server-only)
208 - ✅ Client code only calls public endpoints
209 - ✅ No `import.meta.env.GITHUB_TOKEN` in `.astro` client code
210
211 ### Risk 4: Token in Error Messages
212
213 **Prevention**:
214 ```typescript
215 // Safe error handling:
216 return new Response(
217 JSON.stringify({
218 error: 'Internal server error',
219 message: error instanceof Error ? error.message : 'Unknown error'
220 // No token details included
221 }),
222 { status: 500 }
223 )
224 ```
225

239 ## 🔐 Token Management Best Practices
240
241 ### Creating Tokens
242
243 1. **Use Fine-Grained Tokens** (Recommended)
244 - Scope to specific repository only
245 - Set to Read-only access
246 - Set expiration date (1 year max)
247
248 2. **Use Classic Tokens** (Alternative)
249 - Minimum scope: `repo` for private repos
250 - Set expiration date
251 - Document creation date
252
253 ### Storing Tokens
254
255 **Development**:
256 ```bash
257 # Store in .env (gitignored)
258 echo "GITHUB_TOKEN=ghp_your_token" > .env
259 ```
260
261 **Production**:
262 - Store in hosting platform's environment variables
263 - Never commit to repository
264 - Use secrets management (Vercel/Netlify/etc.)
265
266 ### Rotating Tokens
267
268 **Schedule**: Every 6-12 months
269
270 **Process**:
271 1. Generate new token
272 2. Update `.env` locally
273 3. Test locally
274 4. Update production environment variables
275 5. Verify production works
276 6. Revoke old token
277 7. Document rotation in calendar
278
279 ### Revoking Tokens
280
281 **When to Revoke**:
282 - Token accidentally committed
283 - Suspected compromise
284 - Employee departure
285 - Regular rotation schedule
286
287 **How to Revoke**:
288 1. Go to https://github.com/settings/tokens
289 2. Find the token
290 3. Click "Delete" or "Revoke"
291 4. Generate new token immediately
292 5. Update all environments
293
294 ## 📊 Security Monitoring
295
296 ### What to Monitor
297
298 1. **GitHub Token Usage**
299 - Check at: https://github.com/settings/tokens
300 - Look for unexpected activity
301 - Monitor rate limits
302
303 2. **API Logs**
304 - Watch for authentication failures
305 - Monitor error rates
306 - Check for unusual traffic patterns
307
308 3. **Environment Variables**
309 - Verify production variables are set
310 - Check they haven't been accidentally removed

312
313 ### Alert on:
314 - Authentication failures
315 - Rate limit exceeded
316 - Unexpected API errors
317 - Token expiration (set calendar reminder)
