CVE-2026-49352
CRITICAL 9.8EPSS 0.6%
9Router is an AI router & token saver. From 0.2.21 until 0.4.44, 9Router used the hardcoded fallback JWT secret 9router-default-secret-change-me in src/app/api/auth/login/route.js, src/middleware.js, and later src/lib/auth/dashboardSession.js, allowing attackers to forge an auth_token cookie when JWT_SECRET was unset. This issue is fixed in version 0.4.44
