CVE-2026-126293
Published:November 13, 2026
Updated:November 13, 2026
NocoDB before 2026.06.2 contains an attachment size limit bypass that allows authenticated Editor users to store oversized files because data-attachment-v3.service.ts trusts the remote server's advertised content length. Attackers can point the v3 upload-by-URL endpoint at a server that understates or omits its length to exhaust disk space or storage quota.
