CVE-2026-33226 Details
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.
A server-side request forgery (SSRF) vulnerability has been identified in Budibase versions through 3.30.6. The issue arises in the REST datasource query preview endpoint, which accepts user-supplied URLs without proper validation. This flaw allows authenticated admin users to access internal services not exposed to the internet, such as cloud metadata endpoints (AWS, GCP, Azure), internal databases, Kubernetes APIs, and other pods on the internal network. Exploiting this vulnerability on GCP can lead to theft of OAuth2 tokens with full access to GCP services. Additionally, the vulnerability enables comprehensive enumeration of internal network services.
