NewCVE-2026-45719 (opens in a new tab)How to fix?
Upgrade @budibase/server to version 3.38.1 or higher.
Overview
@budibase/server is a Budibase Web Server
Affected versions of this package are vulnerable to Arbitrary Code Injection via the calculation parameter in the V1 Views API, which is interpolated directly into a CouchDB reduce function without validation. An attacker can execute arbitrary JavaScript code within the CouchDB JavaScript engine by submitting a crafted value for calculation in a POST request to the affected endpoint. This allows access to document data and persistence of malicious code in the database design document.
Note:
This is only exploitable if the attacker has Builder role permissions.
