Type:

CWE-918 Server-Side Request Forgery (SSRF)

Description

Budibase is a low code platform for creating internal tools, workflows, and admin panels. In versions from 3.30.6 and prior, the REST datasource query preview endpoint (POST /api/queries/preview) makes server-side HTTP requests to any URL supplied by the user in fields.path with no validation. An authenticated admin can reach internal services that are not exposed to the internet — including cloud metadata endpoints (AWS/GCP/Azure), internal databases, Kubernetes APIs, and other pods on the internal network. On GCP this leads to OAuth2 token theft with cloud-platform scope (full GCP access). On any deployment it enables full internal network enumeration. At time of publication, there are no publicly available patches.
