Detailsinfo

A vulnerability classified as critical was found in NocoDB up to 2026.05.0. Affected by this vulnerability is an unknown part of the component spreadsheet-import Endpoint. The manipulation with an unknown input leads to a confused deputy vulnerability. The CWE definition for the vulnerability is CWE-441. The product receives a request, message, or directive from an upstream component, but the product does not sufficiently preserve the original source of the request before forwarding the request to an external actor that is outside of the product's control sphere. This causes the product to appear to be the source of the request, leading it to act as a proxy or other intermediary between the upstream component and the external actor. As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

NocoDB is software for building databases as spreadsheets. Prior to 2026.05.1, the spreadsheet-import endpoint axiosRequestMake could be used as a generic HTTP proxy. Before the fix it was reachable unauthenticated, and its URL-extension allowlist was a regex tested against the full URL string, so URLs whose query string ended in .csv satisfies the gate even though the underlying request is for another file. This vulnerability is fixed in 2026.05.1.

The advisory is shared at github.com. This vulnerability is known as CVE-2026-53931 since 06/11/2026. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Neither technical details nor an exploit are publicly available.
