SCA: security update for budibase (GHSA-82rc-gxrg-v4gf)

high Tenable Cloud Security Plugin ID 442139

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 3.38.2, the file upload endpoint POST
 /api/attachments/process does not enforce active-content restrictions for authenticated users. The checks
 for dangerous file extensions are conditionally wrapped inside if (isPublicUser) or if (isPublicUser ||
 !env.SELF_HOSTED), meaning any authenticated builder can upload executable web content — SVG files with
 inline <script> tags, HTML pages with JavaScript, .js modules — which are then stored in the object store
 (MinIO/S3) with their correct MIME types. When the resulting signed URL is opened by any app user, the
 browser executes the payload. Impact is persistent stored XSS over all application end users. This
 vulnerability is fixed in 3.38.2. (CVE-2026-46426)

Solution

Update the budibase library and its related packages to version 3.38.2 or later.
