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.

GHSA-8rwr-f68v-cvw6 — NocoDB: Attachment Size Limit Bypass via Upload-by-URL

Affected: npm: nocodb

### Summary 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.

### Details The attachments service now checks `NC_ATTACHMENT_FIELD_SIZE` against both the HEAD response's `content-length` and the decoded length of a `data:` URI body before fetching. The local storage plugin additionally sets `maxContentLength` on the axios download so a malicious server cannot stream past the limit.

### Impact Authenticated users with upload permission could attach files larger than the operator-configured limit, defeating storage and bandwidth caps.
