CVE-2026-46551
NocoDB is software for building databases as spreadsheets. Prior to 2026.04.4, the uploadViaURL path in the v1/v2 attachment API did not enforce NC_ATTACHMENT_FIELD_SIZE against the remote content-length or against the response stream. An authenticated user (Editor+) could direct the server to download arbitrarily large files, exhausting disk space and causing denial of service. In packages/nocodb/src/services/attachments.service.ts, the HEAD probe read content-length but never compared it to NC
