      <title>CVE-2026-46551 — NocoDB: Missing File Size Enforcement in Upload-by-URL Allows Denial of Service via Disk Exhaustion</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-46551</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; nocodb&lt;/p&gt;
&lt;p&gt;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_ATTACHMENT_FIELD_SIZE; the subsequent storageAdapter.fileCreateByUrl() performed the download without maxContentLength. This vulnerability is fixed in 2026.04.4.&lt;/p&gt;</description>
