CVE-2026-73617 budibase CVE debrief

Who should care

Budibase users, administrators, and security teams should be aware of this vulnerability and take steps to patch or mitigate it. This includes reviewing Budibase deployments, ensuring proper access controls, and monitoring for suspicious activity. Additionally, security teams should consider implementing compensating controls for exposed systems while remediation is scheduled and verified. IT operations teams may need to review and update incident response plans to address potential NoSQL injection attacks. Budibase developers should also review the MongoDB datasource integration and update it according to the vendor's security advisory. Furthermore, vulnerability management teams should track exceptions, retest remediated assets, and close the item only after evidence is documented. Lastly, asset inventory managers may need to verify that all Budibase instances are accounted for and up-to-date with the latest security patches. Compliance teams should ensure that relevant regulations and standards are being met in the remediation process. Communication teams should also be informed to provide guidance to stakeholders on the potential impact and mitigation strategies for this vulnerability. Lastly, threat intelligence teams may need to monitor for potential exploitation attempts and provide early warnings to affected organizations. The communication and coordination among these teams are crucial to effectively address this vulnerability and minimize potential risks. In general, any team that interacts with Budibase or is responsible for its security, should be aware of this vulnerability and take necessary actions to mitigate it. The scope of impact may vary depending on the specific use case and deployment of Budibase within an organization. Therefore, a thorough review of the current configurations and potential exposure is necessary to determine the appropriate course of action. This may involve collaboration with other teams, such as development, operations, and compliance, to ensure a comprehensive approach to addressing this vulnerability. By taking a proactive and coordinated approach, organizations can minimize the risks associated with this vulnerability

Technical summary

Budibase before 3.40.0 contains a NoSQL injection vulnerability in the MongoDB datasource integration. User-supplied parameters are enriched with handlebars using noEscaping: true and parsed without operator filtering, allowing attackers to inject MongoDB operators. This could lead to unauthorized data access, modification, or execution of JavaScript via $where operators. Affected organizations should prioritize patching to version 3.40.0 or later and restrict user-supplied input to prevent MongoDB operator injection.

Defensive priority

Organizations using Budibase before version 3.40.0 should prioritize patching to prevent potential NoSQL injection attacks.

Recommended defensive actions

• Patch Budibase to version 3.40.0 or later
• Restrict user-supplied input to prevent MongoDB operator injection
• Monitor for suspicious MongoDB queries
• Implement additional access controls for MongoDB operations
• Review Budibase deployment configurations and ensure proper access controls are in place
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Verify that all Budibase instances are accounted for and up-to-date with the latest security patches

Evidence notes

The CVE description indicates a NoSQL injection vulnerability in Budibase before 3.40.0, allowing attackers to inject MongoDB operators through query parameters. Evidence is based on official CVE and NVD records. To verify, defenders should review Budibase documentation, check MongoDB datasource integration configurations, and monitor for suspicious queries. Budibase users should also review their deployment configurations and ensure proper access controls are in place.
