CVE-2026-73300Public exploitNetwork attack vector

Database compromise via enabled multiple SQL statements

Published Aug 12, 2026 · Updated Aug 12, 2026

SQL injection in Budibase before 3.40.0 allows remote attackers to compromise connected MySQL databases through crafted user input. The MySQL integration constructor in packages/server/src/integrations/mysql.ts enables multipleStatements for every connection, so injected semicolons are processed as additional SQL commands. Exploitation requires user interaction and a configured MySQL data source; resulting access is bounded by the database account used by Budibase.
