CVE-2026-24766: Nocodb

Medium severity, CVSS 4.9. EPSS: 0.4% chance of exploitation in the next 30 days.

NocoDB is software for building databases as spreadsheets. Prior to version 0.301.0, 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. Version 0.301.0 patches the issue.

Affected products

• Nocodb Nocodb: before 0.301.0 (fixed in 0.301.0)
