CVE-2026-62327Public exploitNetwork attack vector

API key disclosure via unauthenticated usage route

Published Jul 13, 2026 · Updated Jul 13, 2026

Information disclosure in Decolua 9Router 0.4.41 and earlier allows remote attackers to retrieve connected-provider API keys. The unauthenticated Next.js /api/usage/stats route returns complete plaintext keys with usage, cost, and request metadata instead of requiring authentication or masking credentials. A single network request needs no account or user interaction and exposes keys for unauthorized provider use, billing fraud, and quota exhaustion.
