NocoDB Missing Ownership Validation in MCP Token Operations

The MCP token service did not validate token ownership, allowing a Creator within the same base to read, regenerate, or delete another user's MCP tokens if the token ID was known. McpTokenService.get(), regenerateToken(), and delete() did not filter by fk_user_id.

What happened

Summary

The MCP token service did not validate token ownership, allowing a Creator within the same base to read, regenerate, or delete another user's MCP tokens if the token ID was known.

Details

McpTokenService.get(), regenerateToken(), and delete() did not filter by fk_user_id. The analogous ApiTokensService correctly enforced ownership.

Impact

Limited — requires Creator role and knowledge of target token ID. Primary risk is denial of service (invalidating tokens) and scoped token disclosure.

About this data

This record was ingested from a data source. Retrieved: Nov 6, 2026, 00:35 UTC. Ingestion is not an independent editorial investigation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
