Authentication library is on a recent release

Authentication libraries receive security patches — CVEs in next-auth, @supabase/supabase-js, and similar packages have historically enabled token forgery, session bypass, and privilege escalation. CWE-1395 (Dependency on Vulnerable Third-Party Component) and OWASP A06 (Vulnerable and Outdated Components) directly cover this. SLSA L2 supply-chain provenance requires component currency verification. A library that is multiple major versions behind may lack patches for known exploitable vulnerabilities and lose access to security advisory channels entirely.

Check installed versions against latest stable releases and scan for known advisories:

# Check current vs. latest for common auth libraries
npm outdated next-auth @clerk/nextjs @supabase/supabase-js lucia @auth0/nextjs-auth0 2>/dev/null

# Check for known security advisories
npm audit --production 2>/dev/null | grep -i auth

Enable Dependabot or Renovate via .github/dependabot.yml for automated update PRs. Pin auth library versions in package.json to a specific minor version and use the PR-based update workflow to review changelogs before merging. Do not auto-merge major version bumps for auth libraries — review the changelog for breaking changes in session handling.
