Vulnerability
An unauthenticated caller can trigger paid model inference or read operational endpoints without credentials, enabling cost-exhaustion (denial of service) and information disclosure. In a clinical deployment this can make the Co-Pilot unavailable when a physician needs it, and inflate cost unpredictably.
Reproduction (synthetic data only)
Run against the deployed target (https://copilot-agent-production-0395.up.railway.app):
0. POST /v1/briefings (auth: none) payload: {'raw': {}}
The platform uses only synthetic demo patients and planted canaries; no real PHI is involved.
Observed vs expected
- Observed: HTTP 200 in 120 ms. Oracle
unauthenticated_or_unexpected_statusmatched, confirming the attack succeeded. - Expected (safe): An unauthenticated or cross-patient request is refused (401/403).
Recommended remediation
Require authentication before any processing on this route (a signed request or a short-lived ticket) and return 401 for unauthenticated requests. Restrict /metrics and /ready to the internal network or require auth; do not expose them publicly.
Fix validation
Fixed and validated (RED → GREEN). The remediation was applied and redeployed; the regression harness (forge.regress) replayed this exact attack against the new target version and the deterministic oracle now returns the expected safe behaviour (a 401 rejection), confirming the hole is closed. This counts as fixed only because the oracle no longer matches the unsafe condition — not merely because output changed.
