SCA: security update for @budibase/server (GHSA-g6qx-g4pr-92v7)

high Tenable Self-Hosted Container Security Plugin ID 443121

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Budibase is an open-source low-code platform. Prior to 3.39.0, the OAuth2 token fetch function in
 packages/server/src/sdk/workspace/oauth2/utils.ts uses raw fetch(config.url) with no SSRF protection. The
 safe wrapper fetchWithBlacklist() exists in the same codebase and is used in every other outbound HTTP
 call (automation steps, plugin downloads, object store), but was not applied to the OAuth2 token endpoint.
 A user with BUILDER role can point the OAuth2 token URL to internal services (CouchDB, cloud metadata) to
 exfiltrate sensitive data. This vulnerability is fixed in 3.39.0. (CVE-2026-48146)

Solution

Update the @budibase/server library and its related packages to version 3.39.0 or later.
