NocoDB: Attachment Size Limit Bypass via Upload-by-URL

Title source: cna
STIX 2.1

Description

NocoDB is software for building databases as spreadsheets. Prior to 2026.04.1, the upload-by-URL path did not enforce NC_ATTACHMENT_FIELD_SIZE against either the remote file's advertised Content-Length or the decoded length of a data: URI, allowing an authenticated user to bypass the configured per-file size limit. This vulnerability is fixed in 2026.04.1.
