CVE-2026-116120 · Severity: medium · CVSS 5.6 · Published 2026-10-26

NocoDB, a self-hosted database platform and Airtable alternative, lacks rate limiting on unauthenticated signup and password-reset endpoints. An attacker can exploit this to exhaust server resources through repeated requests, potentially causing denial of service. The vendor has acknowledged this as intentional design and has not provided a fix.

## How to fix


Implement manual rate limiting at the application or infrastructure level on the signup, password-forgot, and token endpoints; alternatively, restrict access to these endpoints through a WAF or reverse proxy.

## Technical details

The vulnerability exists in the PublicApiLimiterGuard component, specifically affecting the UserRefreshToken.deleteAllUserToken function in the /auth/user/signup endpoint. The issue involves insufficient rate limiting on unauthenticated endpoints (signup, password-forgot) and per-request token invalidation, allowing an attacker to trigger resource exhaustion remotely through repeated API calls. While attack complexity is high and exploitability is considered difficult, the lack of authentication requirements makes remote exploitation feasible.
