NocoDB Missing Ownership Validation in MCP Token Operations
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.
