CVE-2026-53927: NocoDB: Server-Side Request Forgery via Spreadsheet Fetch URL

June 17, 2026

The spreadsheet-fetch endpoint (axiosRequestMake) accepted URLs whose path contained a permitted extension anywhere in the string, and applied a hand-rolled regex blocklist that omitted 127.0.0.0/8 and 169.254.0.0/16, allowing the cloud-metadata endpoint to be reached with a crafted URL.
