CVE-2026-64657

What it is

Budibase is an open-source low-code platform. Prior to 3.39.19, the PostgreSQL datasource connector in packages/server/src/integrations/postgres.ts interpolates the user-controlled schema configuration field into a SET search_path statement without escaping embedded double quotes, allowing an authenticated administrator who saves or tests the datasource to execute arbitrary SQL through the simple query protocol. This issue is fixed in version 3.39.19.
