Detailsinfo

A vulnerability classified as critical has been found in budibase up to 3.38.x. This affects an unknown code of the component HTTP Request Handler. The manipulation with an unknown input leads to a server-side request forgery vulnerability. CWE is classifying the issue as CWE-918. The web server receives a URL or similar request from an upstream component and retrieves the contents of this URL, but it does not sufficiently ensure that the request is being sent to the expected destination. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Budibase is an open-source low-code platform. Prior to 3.39.0, the executeQuery automation step in Budibase accepts a queryId from automation step inputs and passes it directly to the query execution controller without additional validation. When combined with a REST datasource configured to target internal infrastructure, this creates a server-side request forgery path where automation execution causes the Budibase server to make outbound HTTP requests to attacker-influenced destinations. The automation output then returns the response, potentially exposing internal service data. This vulnerability is fixed in 3.39.0.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-48128 since 05/20/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Additional levels of successful authentication are needed for exploitation. Neither technical details nor an exploit are publicly available.

Upgrading to version 3.39.0 eliminates this vulnerability.
