Description

Budibase before 3.40.0 contains an unauthenticated SQL injection vulnerability in webhook-triggered automations with EXECUTE_QUERY steps. Attackers can POST attacker-controlled JSON to the webhook trigger endpoint to inject SQL payloads that execute with builder-configured database credentials, enabling data exfiltration, modification, and persistence in connected datasources like Snowflake.
