CVE ID :CVE-2026-56679

Published : July 15, 2026, 9:16 p.m. | 17 minutes ago

Description :9Router is an AI router & token saver. Prior to 0.5.4, the PATCH /api/settings endpoint writes the entire request body to persistent settings without a field whitelist, allowing an authenticated user to set security-critical fields such as requireLogin and disable authentication for the whole application, exposing protected routes such as /api/keys and /api/providers to unauthenticated access. This issue is reported as fixed in version 0.5.4.

Severity: 8.7 | HIGH
