📝 WalkthroughWalkthroughAuthentication setup and login routes now apply an in-memory per-IP limit of 10 attempts per 15-minute window. Excess requests receive HTTP 429 responses. ChangesAuthentication rate limiting
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟠 High · up to The change adds authentication rate limiting, but its per-IP tracking map can grow without bound when requests come from many source addresses, potentially exhausting server memory and causing an outage. The map should be bounded or expired entries should be removed before merging. Suggested reviewers: 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

Bound the loginAttempts map.
loginAttempts stores an entry for every source IP, but no code removes expired entries. A public attacker using many source IPs can grow this map for the lifetime of the process. The counter resets after 15 minutes, but the stored entry remains. Use an expiring, bounded store, or prune expired entries and enforce a maximum number of tracked IPs.

Summary
Fix high severity security issue in
server/auth.js.Vulnerability
V-001server/auth.js:121Description: The /api/auth/login and /api/auth/setup endpoints have no rate limiting. Each login attempt invokes crypto.scryptSync which is CPU-intensive by design. An attacker can send unlimited login requests to exhaust server CPU resources or brute-force the password.
Evidence
Exploitation scenario: Send thousands of concurrent POST requests to /api/auth/login with arbitrary passwords.
Scanner confirmation: multi_agent_ai rule
V-001flagged this pattern.Production code: This file is in the production codebase, not test-only code.
Threat Model Context
This is a Node.js library - vulnerabilities affect downstream consumers who use this package.

The change is scoped to 1 file on the vulnerable path; it only tightens handling of untrusted input and leaves valid inputs unaffected.
