What is CVE-2026-64657?
CVE-2026-64657 is a high-severity SQL injection vulnerability in budibase, published on 17 Aug 2026. An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.
Official description
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.
