Description
n8n contains a critical Remote Code Execution (RCE) vulnerability in its workflow Expression evaluation system. Expressions supplied by authenticated users during workflow configuration may be evaluated in an execution context that is not sufficiently isolated from the underlying runtime.
An authenticated attacker could abuse this behavior to execute arbitrary code with the privileges of the n8n process. Successful exploitation may lead to full compromise of the affected instance, including unauthorized access to sensitive data, modification of workflows, and execution of system-level operations.

---END_METADATA---
Description Summary:
A command injection vulnerability in React create-react-app (up to version 5) allows remote attackers to execute arbitrary OS commands.
Executive Summary:
A vulnerability in React create-react-app allows for OS command injection, potentially leading to unauthorized system access and execution of arbitrary code.
Vulnerability Details
CVE-ID: CVE-2026-14802
Affected Software: React create-react-app
Affected Versions: react create-react-app: up to 5
Vulnerability: The software is vulnerable to CWE-78 (OS Command Injection) and CWE-77 (Command Injection). This allows an attacker to inject and execute system-level commands, potentially gaining control over the environment where the software is being utilized.
Business Impact
The vulnerability is rated with a CVSS score of 7.3 (High). Successful exploitation could lead to a complete compromise of the build environment or developer workstation, potentially allowing for supply chain attacks, data exfiltration, or lateral movement within the corporate network.
Remediation Plan
Immediate Action: Apply vendor security updates immediately. Users should check for the latest versions of create-react-app and migrate away from vulnerable versions up to 5.
Proactive Monitoring: Monitor build pipelines and development environments for unexpected process executions or unusual modifications to system configurations.
Compensating Controls: Ensure that build environments are isolated and run with the principle of least privilege to minimize the potential impact of command execution.
Exploitation Status
Public Exploit Available: False
Analyst Notes: As of July 6, 2026, there is no public information indicating active exploitation of this vulnerability. However, the nature of command injection flaws necessitates prompt remediation to prevent potential supply chain compromise.
Analyst Recommendation
Given the risk to development and build environments, it is critical to update your dependencies and ensure that create-react-app is not running in an insecure state. Prioritize this update to maintain the integrity of your software development lifecycle.
