CVE-2026-53931Public exploitNetwork attack vector

Unauthenticated SSRF via full-URL extension regex

Published Jun 23, 2026 · Updated Jun 23, 2026

Server-side request forgery in NocoDB before 2026.05.1 allows remote attackers to proxy HTTP requests to internal services. The axiosRequestMake spreadsheet-import endpoint applies an unanchored extension regex to the full URL, letting a .csv query suffix pass a request for another path. No authentication is required; the NocoDB host originates the request and exposes reachable internal HTTP services to probing or response relay.
