SCA: security update for @budibase/server (GHSA-v7j5-vc4m-723w)

high Tenable Cloud Security Plugin ID 443782

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, `GET /api/chat-
 links/:instance/:token/handoff` is a public endpoint (no auth required) that performs a permanent, state-
 changing operation: it binds an external chat identity (Slack/Discord/MS Teams) to an authenticated
 Budibase user account, with no consent UI and no CSRF protection. The session token in the URL is created
 by the attacker (from their own /link slash command) and embeds the attacker's externalUserId. When an
 authenticated Budibase victim visits the URL, their account is silently and permanently linked to the
 attacker's Slack/Discord identity. The server responds with "Authentication succeeded." — no indication of
 what was linked. This vulnerability is fixed in 3.39.0. (CVE-2026-50132)

Solution

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