# CVE-2026-126272: NocoDB before 2026.09.0 Uncontrolled Resource Consumption via Bulk Record Endpoints

Status: published. Published: 2026-11-13. Updated: 2026-11-13.

NocoDB before 2026.09.0 contains an uncontrolled resource consumption vulnerability that allows authenticated users to bypass bulk row-count limits by using session authentication instead of API tokens. Attackers with Editor write permission on one table can submit hundreds of thousands of rows to v1 and v2 bulk write routes, exhausting database connections, CPU, and memory.
