Severity: High

Component(s): dashboard

Affected file(s):

  • dashboard/src/auth/AuthProvider.tsx
  • dashboard/src/api/client.ts

Problem:
The dashboard stores the JWT in sessionStorage and blindly attaches it as a Bearer token, with no expiry handling, refresh, or idle timeout.

Recommended fix:
Respect exp, add proactive refresh/logout and an idle timeout; longer-term move to an httpOnly cookie (coordinate with P1).

Remediation phase: P4

From the 2026-06-05 three-way review (Claude+Gemini+Grok) — see reports/review-2026-06-05/SYNTHESIS-three-way.md (finding H6) and REMEDIATION-PLAN.md (P4).
