  5. Dependency vulnerability closure: Completed (pnpm audit --prod => no known vulnerabilities).

Remediation Implemented

  1. Migration chain repair:

    • Updated apps/api/prisma/migrations/20260123_add_direct_reporting_support/migration.sql.
    • Added ordering-safe creation/guards so Buyer-related changes no longer fail before the later buyer bootstrap migration.

  2. Dependency remediation:

    • Updated apps/app/package.json to next@15.5.10 and eslint-config-next@15.5.10.
    • Updated apps/www/package.json to next@15.5.10.
    • Updated apps/api/package.json to nodemailer@^7.0.11 and undici@^6.23.0.
    • Added workspace overrides in package.json:
      • jws@3.2.3
      • qs@6.14.2
      • lodash@4.17.23
      • js-yaml@4.1.1
    • Regenerated dependency lockfile (pnpm-lock.yaml).

  3. Next.js compatibility patch after upgrade:

    • Updated apps/app/src/lib/session-actions.ts for async cookies() handling in current Next runtime.

Verification Evidence

  1. Clean migration deployment test:

    • Fresh DB: taxpoynt_migrate_smoke
    • Command: pnpm --filter @taxpoynt/api run prisma:migrate:deploy
    • Result: all migrations applied successfully.

  2. Security dynamic tests:

    • test/health.e2e-spec.ts passed (2/2).
    • test/security-dast.e2e-spec.ts passed (4/4).

  3. Static/SAST checks:

    • pnpm --filter @taxpoynt/api run lint passed.
    • pnpm --filter @taxpoynt/api run typecheck passed.
    • pnpm --filter @taxpoynt/app run typecheck passed.
    • pnpm --filter @taxpoynt/www run typecheck passed.

  4. Dependency audit:

    • pnpm audit --prod (workspace): No known vulnerabilities found.
    • pnpm audit --prod (apps/api): No known vulnerabilities found.

Baseline vs Final

  1. Baseline vulnerabilities (Report 2): 23 (1 critical, 9 high, 10 moderate, 3 low).
  2. Final vulnerabilities (this closure report): 0 known vulnerabilities.
  3. SQLi exploitability status: not confirmed in tested SI/AP/auth HTTP paths.
  4. E2E boot status: healthy and reproducible for security suites.

Residual Notes

  1. This closure is based on current lockfile and current advisory database state at execution time.
  2. New advisories may appear later; keep audit checks in CI to maintain this posture.
