NocoDB: Missing Ownership Check in MCP Attachment Read

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, a low-privilege MCP token holder with knowledge of an attachment path could read any file in shared storage, including attachments belonging to other bases and workspaces, because the MCP readAttachment tool did not verify the file's ownership. This vulnerability is fixed in 2026.05.1.

NocoDB: Missing Ownership Validation in MCP Token Operations

NocoDB is software for building databases as spreadsheets. Prior to version 0.301.3, 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. This issue has been patched in version 0.301.3.

NocoDB: Hidden Column Exposure in Public Shared View Endpoints

NocoDB is software for building databases as spreadsheets. Prior to 2026.04.1, Public shared-view endpoints exposed values from columns that the view owner had hidden, via three independent paths: groupBy returned raw values for any column named in the request, filter and sort arrays operated on hidden columns enabling boolean-blind extraction, and the related-data list accepted arbitrary link-column IDs from other tables in the same base. This vulnerability is fixed in 2026.04.1.
