CVE-2026-64657Network attack vectorHinoki check available

Arbitrary SQL execution via search_path injection

Published Aug 17, 2026 · Updated Aug 18, 2026

SQL injection in the PostgreSQL datasource connector in Budibase before 3.39.19 allows remote authenticated users to execute arbitrary SQL. In packages/server/src/integrations/postgres.ts, the connector builds a SET search_path statement by interpolating the schema configuration into quoted identifiers and passes the result to this.client.query() without escaping embedded double quotes or parameterizing the value. Exploitation requires administrator access to save or test a PostgreSQL datasource, and injected statements run with the privileges of the configured database user because node-postgres accepts semicolon-separated statements in the simple query protocol.
