⚠️ DEPRECATED - DO NOT USE

This document contains INCORRECT risk assessment based on misunderstanding test mode capabilities.

Correct Analysis: See STRIPE_STATUS_CLARIFICATION_2025-10-21.md

Actual Status: Test mode with test keys - LOW RISK (not moderate)

Date Deprecated: 2025-10-21

URGENT: Stripe Security Assessment Correction

Date: 2025-10-21 Priority: 🚨 HIGH Status: CORRECTION TO PREVIOUS AUDIT

Critical Discovery

Previous Assessment: "Test keys only, no real money, low risk"

ACTUAL SITUATION: Stripe dashboard shows:

• Real transactions: NZ$4.56 incoming
• Real bank account connected
• Real payout schedule (delayed by Labour Day bank holiday)
• Balance: -NZ$0.05 available
• Business name: John Geoffrey Stroh

---

Risk Re-Assessment

Previous Risk Level: 🟢 Minimal

ACTUAL Risk Level: 🟡 MODERATE TO HIGH

Why the Risk is Higher:

Even though the API keys start with sk_test_ (test mode), the Stripe account appears to be:

1. Connected to a real bank account (for payouts)
2. Processing real transactions (NZ$4.56 is real money)
3. Associated with real business identity (John Geoffrey Stroh)

---

What "Test Mode" Actually Means

Test Keys CAN Process Real Money If:

1. Test Mode with Real Bank Account

   • Test mode keys (sk_test_*) are used
   • But connected to real bank account for payout testing
   • Small real transactions may occur during setup/testing
   • This appears to be your current situation

2. Test Cards vs Real Payment Methods

   • Test mode typically uses fake card numbers (4242 4242 4242 4242)
   • But if real payment methods are used, real money moves
   • Balance of -NZ$0.05 suggests real transaction processing

---

Revised Security Implications

If These Keys Are Compromised:

Immediate Risks:

• ❌ Attacker could create unauthorized checkout sessions
• ❌ Attacker could view transaction history
• ❌ Attacker could access customer payment information
• ❌ Attacker could modify webhook endpoints
• ❌ Attacker could potentially trigger refunds or disputes
• ⚠️ Could affect real bank account connected to Stripe

Financial Impact:

• Current balance: Small (NZ$4.56 incoming, -NZ$0.05 available)
• But: Access to Stripe dashboard = access to all historical transactions
• But: Could be used to create fraudulent charges
• But: Real bank account is connected (payout risk)

---

Current Security Status (Re-Evaluated)

✅ Good News: Keys Are Still Secure

From technical audit (still valid):

• ✅ Keys not in git repository
• ✅ Keys not in public directories
• ✅ Keys not in database
• ✅ Keys not in git history
• ✅ .env properly excluded
• ✅ Search doesn't expose keys

This means: Keys are currently secure, but the IMPACT if they were exposed is higher than initially stated.

Immediate Recommendations

1. Clarify Stripe Mode Status (URGENT)

Action Required: Log into Stripe Dashboard and verify:

Stripe Dashboard → Top-left toggle
- Is it showing "Test mode" or "Live mode"?
- If "Test mode": Why are there real money transactions?
- If "Live mode": Keys in .env should be sk_live_*, not sk_test_*

Possible Scenarios:

Scenario A: Test mode with real bank for payout testing

• Keys are test keys (sk_test_*)
• Real bank account connected to test payments
• Small real transactions expected during setup
• Risk: Moderate (limited scope, but real money)

Scenario B: Live mode but viewing wrong dashboard section

• Keys in .env are test keys
• But separate live mode is active with real transactions
• Risk: High (need to secure live keys too)

Scenario C: Test keys accidentally processing live transactions

• Stripe misconfiguration
• Risk: Very High (immediate action needed)

2. Verify API Key Type (IMMEDIATE)

Check Stripe Dashboard → Developers → API Keys:

Publishable key: pk_test_* or pk_live_*?
Secret key: sk_test_* or sk_live_*?

Your .env has: sk_test_51RX67k...
Dashboard shows: Real money transactions

These should match the mode (test vs live)

3. Security Hardening (DO NOW)

Even though keys are currently secure:

1. Rotate Test Keys

   • Stripe Dashboard → Developers → API Keys
   • Click "Roll" on secret key
   • Update .env file
   • Restart server
   • Reason: Safety margin if keys were exposed unknowingly

2. Enable Stripe Notifications

   • Stripe Dashboard → Settings → Notifications
   • Enable: "Successful payments", "Failed payments", "Disputes"
   • Reason: Monitor for unauthorized activity

3. Review Recent Activity

   • Stripe Dashboard → Payments
   • Check all recent transactions
   • Verify: You recognize all charges
   • Reason: Detect any unauthorized use

4. Set Up 2FA on Stripe Account

   • Stripe Dashboard → Settings → Security
   • Enable two-factor authentication
   • Reason: Protect dashboard access

4. Restrict API Key Permissions

Stripe allows restricting what test keys can do:

• Stripe Dashboard → Developers → API Keys → Restricted Keys
• Create restricted key with minimal permissions:
  • ✅ Read-only access
  • ✅ Create checkout sessions only
  • ❌ No refunds
  • ❌ No customer data modifications
  • ❌ No webhook endpoint changes

Use restricted key in .env for development

Updated Risk Matrix

Scenario	Current Risk	If Keys Leaked
Test keys + Real bank	🟡 Moderate	🟡 Moderate
Live keys	🔴 High	🔴 Very High
Misconfigured	🔴 High	🔴 Critical

What This Means for Your Security

Keys ARE Secure (Technical Audit Valid)

The original audit findings remain true:

• ✅ No keys in git
• ✅ No keys in public files
• ✅ Proper .env exclusion
• ✅ No database exposure

But Impact of Breach is Higher

Original statement: "Low risk if exposed (test environment only, no real money)"

CORRECTED statement: "Moderate to high risk if exposed (connected to real bank account, processing real transactions even in test mode)"

Action Items (Prioritized)

IMMEDIATE (Next 30 Minutes)

1. ☐ Log into Stripe Dashboard
2. ☐ Verify test mode vs live mode status
3. ☐ Check if real transactions are expected in test mode

SHORT-TERM (Today)

6. ☐ Rotate test API keys as precaution
7. ☐ Update .env with new keys
8. ☐ Restart application server
9. ☐ Test Koha donations still work

Corrected Conclusion

Security Posture: ✅ Currently Secure

Your credentials are not exposed. The technical implementation is sound.

Risk Level: 🟡 Higher Than Initially Stated

The keys have access to:

• Real bank account information
• Real transaction processing (even in test mode)
• Customer payment data
• Business financial information

Therefore: Treat these keys with the same security as live production keys.

---

My Mistake

I apologize for the initial assessment that characterized test keys as "low risk, no real money." I should have:

1. Asked about real vs test transactions
2. Verified the account setup status
3. Not assumed "test keys = fake money"

The technical security audit is correct (keys are secure), but the risk characterization was wrong.

Verification Questions for User

To provide accurate guidance, please confirm:

1. Stripe Dashboard Mode: Are you in "Test mode" or "Live mode"?
2. Transaction Source: Where did the NZ$4.56 transaction come from?
3. Bank Account: Is a real bank account connected in test mode?
4. Expected Behavior: Did you intentionally process a real transaction?
5. Key Type: Do you have separate live keys (sk_live_*) in addition to test keys?

---

Status: Awaiting user clarification to provide final security recommendations

Next Steps:

1. User confirms Stripe mode and transaction source
2. I provide mode-specific security guidance
3. User implements recommended hardening measures
