Likely Mitigating ControlsAI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

SI-10 Information Input Validation
addresses: CWE-78 CWE-89

Validates inputs to block special elements that would alter OS command execution.

CA-8 Penetration Testing
addresses: CWE-89

Penetration testing uses SQL injection payloads against database interfaces, identifying and supporting fixes for SQL injection weaknesses.

SC-27 Platform-independent Applications
addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.

NVD Description

Twenty is an open source CRM. From 1.7.7 through 1.16.7, a critical Remote Code Execution (RCE) vulnerability exists in Twenty CRM via a chained SQL Injection and PostgreSQL COPY TO PROGRAM attack. If Postgres user is a super user then…

more

any authenticated user can execute arbitrary OS commands on the database server by injecting SQL through the unsanitized timeZone parameter in the REST API groupBy endpoint. The timeZone field within the group_by query parameter is directly interpolated into a raw SQL expression using JavaScript template literals without any parameterization, validation, or escaping. This affects engine/api/graphql/graphql-query-runner/group-by/resolvers/utils/get-group-by-expression.util.ts.

Regulatory context (EU CRA / NIS2 / DORA / UK NIS Regulations)

EU Cyber Resilience Act — coordinated disclosure

Critical and high-severity vulnerabilities in products with digital elements may trigger coordinated-disclosure obligations under the EU Cyber Resilience Act (CRA, Regulation 2024/2847). Manufacturers placing products on the EU market must notify ENISA and the relevant CSIRTs without undue delay once active exploitation is known.
