Published Aug 13, 2026
·
Updated

Budibase before 3.40.0 contains an unauthenticated SQL injection vulnerability in webhook-triggered automations with EXECUTEQUERY 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.

Affected Software

1 affected component
budibase Budibase<3.40.0

Remediation

Recommended actions to resolve this vulnerability, in priority order.

  1. Upgrade

    Upgrade Budibase to a version that resolves this vulnerability.

    Fixed in 3.40.0
  2. Compensating control

    Ensure the webhook trigger endpoint used by webhook-triggered automations is authenticated/does not allow unauthenticated POSTs of attacker-controlled JSON (so EXECUTE_QUERY steps cannot be triggered without authorization).
