+# Snyk Vulnerability Investigation Report
+
+## Issue ID
+
+SNYK-JS-NEXT-9508709
+
+## Snyk Alert Details
+
+- **Vulnerability Title:** Improper Authorization in Next.js
+- **Severity:** Critical (CVSS 851/1000)
+- **Package Name (reported):** NVD
+- **Project:** continuedev/continue:docs/package.json
+- **Issue Type:** Improper Authorization
+- **Reported Fix:** Upgrade to Next.js versions 12.3.5, 13.5.9, 14.2.25, 15.2.3, or 15.3.0-canary.12+
+
+## Investigation Findings
+
+### 1. Package Analysis
+
+**Result:** `next` (Next.js) package is **NOT** present in the project.
+
+**Evidence:**
+
+```bash
+$ cd docs && npm list next
+[email protected] /home/user/continue/docs
+└── (empty)
+```
+
+### 2. Direct Dependencies
+
+The `docs/package.json` only contains:
+
+- `@c15t/react@^1.7.0` (dependency)
+- `mintlify@^4.2.3` (devDependency)
+
+No Next.js framework dependency exists.
+
+### 3. Transitive Dependencies Check
+
+Searched the entire `docs/package-lock.json` for Next.js references:
+
+- Found: `next-mdx-remote-client` (a completely different package used by `@mintlify/mdx`)
+- **No `next` package** found in any dependency tree
+
+### 4. NPM Audit Results
+
+```bash
+$ npm audit
+# npm audit report
+
+axios  1.0.0 - 1.11.0
+Severity: high
+...
+
+tar-fs  3.0.0 - 3.1.0
+Severity: high
+...
+
+2 high severity vulnerabilities
+```
+
+**No Next.js vulnerability reported by npm audit.**
+
+## Conclusion
+
+This Snyk alert appears to be a **FALSE POSITIVE** due to one or more of the following reasons:
+
+1. **Package Name Mismatch:** The webhook payload shows "packageName": "NVD" which is incorrect
+2. **Incorrect Attribution:** Snyk may have incorrectly identified `next-mdx-remote-client` as `next`
+3. **Stale Alert:** The alert may reference an old dependency that no longer exists
+4. **Integration Issue:** The Snyk GitHub integration may have scanning issues
+
+## Recommendations
+
+1. ✅ **Close this Snyk alert** as "False Positive" or "Won't Fix"
+2. ✅ **Review Snyk Integration** to ensure accurate package detection
+3. ✅ **Document findings** for future reference
+4. ⚠️ **Address actual vulnerabilities** found by `npm audit`:
+   - Upgrade `axios` to fix DoS vulnerability
+   - Upgrade `tar-fs` to fix symlink bypass vulnerability
+
+## Action Items
+
+- [ ] Mark Snyk alert as false positive in Snyk dashboard
+- [ ] Review Snyk configuration for `docs/package.json` scanning
+- [ ] Optional: Run `npm audit fix` to address real vulnerabilities
