+# Release v2.0.4 - Security Patch
+
+**Release Date:** May 8, 2026
+
+## 🔒 Security Update
+
+### Fixed
+- **CRITICAL**: JWT Signature Verification Vulnerability (GHSA-223g-f5mq-gw33)
+  - Fixed JWT signature verification that was disabled in authentication middleware
+  - Prevents JWT forgery attacks and unauthorized account takeover
+  - All JWT tokens now properly verified with server secret key
+
+### What Was Fixed
+The application was disabling JWT signature verification with `options={"verify_signature": False}`, which allowed attackers to forge authentication tokens without the server checking the signature.
+
+**Files Updated:**
+- `backend/routes/dashboard.py` - Enabled JWT signature verification
+- `backend/main.py` - Enabled JWT signature verification
+- `backend/activity_logger.py` - Enabled JWT signature verification
+
+**Changes:**
+```python
+# Before (Vulnerable)
+decoded = jwt.decode(token, options={"verify_signature": False}, ...)
+
+# After (Fixed)
+decoded = jwt.decode(token, jwt_secret_key, algorithms=["HS256", "RS256"])
+```
+
+### Security Impact
+- ✅ Tokens without valid signatures are now properly rejected
+- ✅ Attackers can no longer forge authentication tokens
+- ✅ Account takeover vulnerability is closed
+- ✅ Server validates token authenticity using cryptographic signature
+
+## 📦 Installation

+- **Reporter:** @krrazee
+- **Remediation Developer:** @0x5t4l1n
+
+## ⚠️ Important Notes
+
+- This is a security release and should be deployed immediately
+- The JWT_SECRET_KEY environment variable must be set (already handled in app configuration)
+- Previous versions (2.0.3 and earlier) are affected and should be updated
+
+## 🚀 Next Steps
+
+1. Install the latest version: `npm install @th30d4y/openlearnx@2.0.4`
+2. Deploy to your environment
+3. Verify JWT authentication is working correctly
+4. Monitor for any authentication-related issues
