Executive Summary

CVE-2026-18816 is an improper authentication vulnerability in Baserow versions up to 2.3.2. It exists in the 2FA Verify Endpoint function verify within backend/src/baserow/api/two_factor_auth/views.py. The flaw allows remote attackers to manipulate the authentication process, though exploitation is difficult due to high complexity.

Detection Guidance

Detection requires checking the Baserow version. Run: docker exec baserow cat /baserow/version.txt or check the web interface version page. If version is <=2.3.2, the system is vulnerable.

Impact Analysis

If exploited, this vulnerability could allow unauthorized remote access to user accounts by bypassing two-factor authentication. Attackers might gain control of accounts, leading to data theft, unauthorized actions, or further compromise of the system. However, the high complexity and difficulty of exploitation reduce the risk.

Compliance Impact

This vulnerability could potentially violate compliance requirements that mandate strong authentication controls, such as GDPR's security principles or HIPAA's access control safeguards. A successful exploit might lead to unauthorized data access, triggering reporting obligations or penalties under these regulations.

Mitigation Strategies

Upgrade Baserow to version 2.3.3 or later immediately. Follow vendor instructions for safe upgrade. Ensure backups are taken before upgrading. Monitor for unauthorized access attempts.
