Alert meAnalysisAIv1 – Mar 12, 2026
Prototype pollution in NocoDB's connection test endpoint allows authenticated org-level creators to disrupt all database write operations application-wide until server restart, with public exploit code available. Although the vulnerability can bypass SUPER_ADMIN authorization checks, the resulting denial of service prevents actual exploitation of elevated privileges. The issue affects versions prior to 0.301.0 with no patch currently available.
Earlier versions of this analysis (1)
Nocodb versions up to 0.301.0 is affected by improperly controlled modification of object prototype attributes (prototype pollution) (CVSS 4.9).
RemediationAI
Monitor vendor advisories for a patch. Restrict network access to the affected service where possible.

This vulnerability (CWE-1321: Improperly Controlled Modification of Object Prototype Attributes (Prototype Pollution)) affects Nocodb. 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
