CVE-2026-24766: NocoDB has Prototype Pollution in Connection Test Endpoint, Leading to DoS

An authenticated user with org-level-creator permissions can exploit prototype pollution in the /api/v2/meta/connection/test endpoint, causing all database write operations to fail application-wide until server restart.

While the pollution technically bypasses SUPER_ADMIN authorization checks, no practical privileged actions can be performed because database operations fail immediately after pollution.
