SCA: security update for @budibase/backend-core (GHSA-gfq7-5x4g-3xhf)

high Tenable Cloud Security Plugin ID 443780

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 3.39.9, authenticated users with automation
 permissions can bypass Budibase's SSRF blacklist through DNS rebinding. The outbound fetch flow validates
 a hostname against the blacklist before the request is sent, but the actual socket connection later
 performs a separate DNS lookup through node-fetch. Since the validated IPs are never pinned to the
 connection, an attacker-controlled hostname can return a public IP during validation and a
 private/internal IP during the real connection. This results in a non-blind SSRF primitive against
 internal services reachable from the Budibase host, including loopback, RFC1918 ranges, and cloud metadata
 endpoints. This vulnerability is fixed in 3.39.9. (CVE-2026-54353)

Solution

Update the @budibase/backend-core library and its related packages to version 3.39.9 or later.
