Threat Model Context

This is a web service - vulnerabilities in request handlers are directly exploitable by remote attackers.

Changes

• config/express.js
• package.json

Behavior Preservation

The change is scoped to 2 files on the vulnerable path, and the project's existing tests still pass, so intended behavior is unchanged.

Verification

• Build passes
• Scanner re-scan confirms fix
• LLM code review passed

---

This change addresses a pattern flagged by static analysis. The code path handles user-influenced input and the fix reduces the attack surface against both manual and automated exploitation.
