CVE-2026-55500: Decolua 9router

Critical severity, CVSS 9.9. EPSS: 0.7% chance of exploitation in the next 30 days.

9Router is an AI router & token saver. Prior to 0.4.80, the /api/settings/database endpoint allows full database export (containing all credentials, API keys, OAuth tokens, and settings) and full database import (complete overwrite) without any authentication requirement beyond the ALWAYS_PROTECTED middleware check, which only validates JWT or CLI token. This issue is fixed in version 0.4.80.

Affected products

• Decolua 9router: before 0.4.80 (fixed in 0.4.80)
