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.
