Executive Summary

This is a denial of service vulnerability in NocoDB versions from 0.300.0 to before 2026.04.4. An authenticated user can crash the server by sending a request with an undefined lookup condition, triggering an unhandled promise rejection in the MetaService metadata logging component. This causes knex binding errors in an unawaited logHelper call, terminating the server process.

Detection Guidance

To detect this vulnerability, monitor NocoDB server logs for unhandled promise rejections or knex binding errors during metadata logging. Check for server crashes after authenticated users send requests with undefined lookup conditions. Review logs for SQL query failures in MetaService.

Impact Analysis

If exploited, this vulnerability can cause the NocoDB server to crash, leading to downtime and loss of service availability. The server would need to be manually restarted, disrupting all users and operations relying on the instance.

Mitigation Strategies

Immediately upgrade NocoDB to version 2026.04.4 or later to patch the vulnerability. If upgrading is not possible, restrict authenticated user access to prevent exploitation. Monitor server logs for signs of attempted attacks and restart the server if crashes occur.
