Assigner: VulnCheck

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.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

Budibase before version 3.40.0 has an unauthenticated SQL injection flaw in webhook-triggered automations that use EXECUTE_QUERY steps. Attackers can send malicious JSON via a webhook to inject SQL commands. These commands run with the database credentials configured by the application builder, allowing unauthorized data access, modification, or deletion in connected databases like Snowflake.

Impact Analysis

If you use Budibase versions before 3.40.0 with webhook automations, attackers could steal, alter, or delete sensitive data in your connected databases. This includes customer information, financial records, or other critical data, potentially leading to data breaches, operational disruptions, or compliance violations.

Compliance Impact

This vulnerability could lead to unauthorized data access or exfiltration, violating GDPR's data protection principles or HIPAA's security requirements. Organizations may face fines, legal penalties, or reputational damage if exploited, as it undermines data confidentiality and integrity mandated by these regulations.

Mitigation Strategies

Upgrade Budibase to version 3.40.0 or later to address the unauthenticated SQL injection vulnerability in webhook-triggered automations.
