CVE-2026-72851Public exploitNetwork attack vector

Unauthenticated SQL injection via raw Snowflake parameter interpolation

Published Aug 13, 2026 · Updated Aug 14, 2026

SQL injection in Budibase Server before 3.40.0 allows remote attackers to alter connected databases through public automation webhooks. The webhook route flattens attacker JSON into EXECUTE_QUERY parameters, and the Snowflake connector renders those values into SQL with no escaping. Exploitation requires a known workspace and webhook UUID pair plus a builder-authored parameterized query; direct row disclosure also requires synchronous automation with a COLLECT step.
