9Router: Mass assignment in PATCH /api/settings allows authenticated authorization downgrade

Published: Jul 15, 2026Updated: Jul 16, 2026 Sources: CVE List NVDCWE-915

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.
