+✅ RELEASE_NOTES_v2.0.4.md created
+✅ Git tag v2.0.4 created and pushed
+✅ Branch `advisory-fix-1` ready for publishing
+
+## Step 1: Prepare for Publishing
+
+```bash
+# Navigate to the frontend directory where package.json is located
+cd frontend
+
+# Verify the version is correct
+cat package.json | grep '"version"'
+# Output should show: "version": "2.0.4"
+
+# Verify npm is installed
+npm --version
+
+# Check npm registry
+npm config get registry
+# Should show: https://registry.npmjs.org/
+```
+
+## Step 2: Login to NPM (if not already logged in)
+
+```bash
+# Login to npm registry
+npm login
+
+# You will be prompted for:
+# - Username: th30d4y
+# - Password: [your npm password]

+# - OTP: [if 2FA is enabled, provide the one-time password]
+```
+
+## Step 3: Publish to NPM
+
+```bash
+# From the frontend directory where package.json is located
+npm publish
+
+# Expected output:
+# npm notice 
+# npm notice 📦  openlearnx@2.0.4
+# npm notice === Tarball Contents ===
+# npm notice ...
+# npm notice === Dist Files ===
+# npm notice ...
+# npm notice === Tarball Details ===
+# npm notice name:          openlearnx
+# npm notice version:       2.0.4
+# npm notice filename:      openlearnx-2.0.4.tgz
+# npm notice published:     [timestamp]
+# npm notice public

+# You should see:
+# openlearnx@2.0.4 | ISC | deps: 39 | versions: 2
+```
+
+## Step 5: Test Installation
+
+```bash
+# Test in a clean directory
+mkdir /tmp/test-openlearnx && cd /tmp/test-openlearnx
+npm init -y
+npm install openlearnx@2.0.4
+
+# Verify the installation
+npm list openlearnx
+# Should show: openlearnx@2.0.4
+```
+
+## Alternative: Using npm ci (for CI/CD)
+
+```bash
+cd frontend
+npm ci  # Install exact versions from package-lock.json
+npm publish
+```
+
+## Troubleshooting
+
+### Issue: "You must be logged in to publish"
+**Solution:** Run `npm login` and verify your credentials
+
+### Issue: "You do not have permission to publish this package"
+**Solution:** 
+- Verify you're logged in: `npm whoami`
+- Check package name in package.json matches your npm account
+- Ensure you have publish permissions for the package
+
+### Issue: "This version has already been published"
+**Solution:** 
+- Use a different version number
+- Use `npm unpublish openlearnx@2.0.4` (if allowed) and republish
+
+### Issue: "npm notice... WARN"
+**Solution:** These are usually non-critical warnings. Review them but the publish should still succeed.
+
+## Post-Publishing
+
+1. **Update the GitHub Release:**
+   - Go to https://github.com/th30d4y/OpenLearnX-ghsa-223g-f5mq-gw33/releases

+# NPM Publishing Guide - v2.0.4 (FIXED)
+
+## 🔧 What Was Fixed
+
+The previous `package.json` had local development links that broke public NPM publishing:
+```json
+// ❌ REMOVED - These break NPM publishing
+"badge": "link:@/components/ui/badge",
+"button": "link:@/components/ui/button",
+"card": "link:@/components/ui/card",
+"progress": "link:@/components/ui/progress",
+"separator": "link:@/components/ui/separator"
+```
+
+These have been removed. The package.json now contains only valid NPM dependencies.
+
+## ✅ Pre-Publishing Checklist
+
+```bash
+# Verify you're on the advisory-fix-1 branch
+git status
+# On branch advisory-fix-1
+
+# Verify package.json is clean
+cat frontend/package.json | grep -i "link:"
+# Should return nothing (no link: dependencies)
+
+# Verify version is set correctly
+cat frontend/package.json | grep '"version"'
+# Should show: "version": "2.0.4"
+
+# Verify publishConfig is correct
+cat frontend/package.json | grep -A 2 "publishConfig"
+# Should show: "registry": "https://registry.npmjs.org"
+```
+
+## 🚀 Step-by-Step NPM Publishing
+
+### Step 1: Navigate to Frontend Directory
+```bash
+cd frontend
+pwd
+# Should output: /home/w4nn4d13/Project/OpenLearnX-ghsa-223g-f5mq-gw33/frontend
+```
+
+### Step 2: Test Package Locally (Optional but Recommended)
+```bash
+# Create tarball to see what would be published
+npm pack
+
+# You should see:
+# npm notice 
+# npm notice 📦  openlearnx@2.0.4
+# npm notice === Tarball Contents ===
+# ...files being packaged...
+# npm notice === Tarball Details ===
+# ...
+# openlearnx-2.0.4.tgz
+
+# Extract and inspect
+mkdir test-package
+cd test-package
+tar -xzf ../openlearnx-2.0.4.tgz
+ls -la package/
+# Verify only necessary files are included
+
+cd ..
+rm -rf test-package
+rm openlearnx-2.0.4.tgz
+```
+
+### Step 3: Login to NPM
+```bash
+npm login
+# You'll be prompted for:
+# Username: [your npm username, e.g., th30d4y]
+# Password: [your npm password]
+# Email: [your npm account email]
+# 2FA OTP (if enabled): [one-time password]
+
+# Verify login was successful
+npm whoami
+# Should output your username
+```
+
+### Step 4: Publish to Public NPM Registry
+```bash
+# From the frontend directory
+npm publish
+
+# Expected output:
+# npm notice 
+# npm notice 📦  openlearnx@2.0.4
+# npm notice === Tarball Contents ===
+# npm notice name:          openlearnx
+# npm notice version:       2.0.4
+# npm notice filename:      openlearnx-2.0.4.tgz
+# npm notice published:     [timestamp]
+# npm notice public
+# npm notice access:        public
+# npm notice ...
+```
+
+### Step 5: Verify Publication
+```bash
+# Check on NPM registry
+npm view openlearnx
+
+# Check specific version
+npm view openlearnx@2.0.4
+
+# Check package page
+# Visit: https://www.npmjs.com/package/openlearnx
+```
+
+### Step 6: Test Installation from Another Directory
+```bash
+# Go to a different directory
+cd /tmp
+mkdir openlearnx-test
+cd openlearnx-test
+npm init -y
+
+# Install the published package
+npm install openlearnx@2.0.4
+
+# Verify installation
+ls node_modules/openlearnx/
+npm list openlearnx
+# Should show: openlearnx@2.0.4
+```
+
+## 🔍 Troubleshooting
+
+### Issue: "npm ERR! code EUNSUPPORTEDPROTOCOL - Unsupported URL Type "link:""
+**Status:** ✅ FIXED in this version
+**Cause:** Local development dependencies were in package.json
+**Solution:** Already applied - link: dependencies removed
+
+### Issue: "npm ERR! code E401 - 401 Unauthorized"
+**Cause:** Not logged in or token issue
+**Solution:** 
+```bash
+npm logout
+npm login
+# Re-enter credentials
+```
+
+### Issue: "npm ERR! 404 - Package not found"
+**Cause:** Package not yet published or wrong registry
+**Solution:**
+```bash
+# Verify publishConfig
+cat package.json | grep -A 2 "publishConfig"
+# Should point to: https://registry.npmjs.org
+
+# Verify you're publishing to the right registry
+npm config get registry
+# Should be: https://registry.npmjs.org
+```
+
+### Issue: "You do not have permission to publish this package"
+**Cause:** Package name collision or permission issue
+**Solution:**
+```bash
+# Check if package already exists on someone else's account
+npm view [package-name]
+
+# If you need a different name, update package.json:
+# "name": "openlearnx-v2"
+```
+
+## 📦 Package Contents

+# 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
+
+### NPM
+```bash
+npm install @th30d4y/openlearnx@2.0.4
+```
+
+### Yarn
+```bash
+yarn add @th30d4y/openlearnx@2.0.4
+```
+
+### PNPM
+```bash
+pnpm add @th30d4y/openlearnx@2.0.4
+```
+

+
+### The Error
+```
+npm ERR! code EUNSUPPORTEDPROTOCOL
+npm ERR! Unsupported URL Type "link:": link:@/components/ui/badge
+```
+
+### The Root Cause
+`package.json` had local development dependencies that only work in monorepo/development:
+```json
+❌ "badge": "link:@/components/ui/badge",
+❌ "button": "link:@/components/ui/button",
+❌ "card": "link:@/components/ui/card",
+❌ "progress": "link:@/components/ui/progress",
+❌ "separator": "link:@/components/ui/separator"
+```
+
+### The Fix Applied
+Removed all `link:` dependencies from `frontend/package.json`.
+These are internal component references only needed during development.
+
+## 🚀 Ready to Publish
+
+### Current Status
+- ✅ Security fix complete
+- ✅ Version bumped to 2.0.4
+- ✅ Package.json cleaned (no link: dependencies)
+- ✅ All documentation created
+- ✅ Git history clean and pushed
+- ✅ Tag v2.0.4 created and pushed
