medium Tenable Self-Hosted Container Security Plugin ID 443794

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 3.39.3, the application server exposes an
unauthenticated endpoint that generates S3 PutObject presigned URLs using credentials stored in a
workspace datasource. The route is protected only by the recaptcha middleware and does not require
authentication, table permission, datasource permission, or builder access. A public caller who knows a
workspace ID and S3 datasource ID can request a signed upload URL for attacker-controlled bucket and key
values. This vulnerability is fixed in 3.39.3. (CVE-2026-50136)

Solution

Update the @budibase/server library and its related packages to version 3.39.2 or later.
