What is CVE-2026-48128?
CVE-2026-48128 is a medium-severity server-side request forgery vulnerability in budibase, published on 27 May 2026. An attacker needs administrator access to exploit it, with no action from the victim.
Official description
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.
Weakness: CWE-918
