Sandboxing isolates untrusted code or files so analysts and security tools can observe behavior and limit damage from malware.

Background for this topic.
A sandbox is an isolated environment for running or inspecting software, files, or workloads without giving them the same access as the host system. In security, it commonly supports malware analysis, suspicious-file detonation, browser and application isolation, and safe testing of potentially vulnerable code. Isolation may rely on virtual machines, containers, operating-system controls, or combinations of these mechanisms.
Sandboxes reduce risk but are not automatically safe: vulnerabilities in the sandbox or hypervisor can enable an escape, and malware may detect analysis conditions and change its behavior. Effective deployments restrict privileges, filesystem access, credentials, and network connectivity; reset environments after use; and monitor activity. Analysts should also protect submitted samples, which can contain confidential data. Sandbox observations can supply threat-intelligence indicators and help validate detections, but a clean result is not proof that code is benign.
Web-Based Client on Local Host Didn't Sanitize InputsVideo camera surveillance management software made by South Korean manufacturer Idis is susceptible to a one-click attack giving hackers the power to execute arbitrary code. The vulnerability allows an attacker to escalate beyond the browser sandbox and achieve code execution on the host.
Two vulnerabilities in the n8n workflow automation platform could allow attackers to fully compromise affected instances, access sensitive data, and execute arbitrary code on the underlying host. [...]
Two critical security flaws in n8n have exposed sandboxing vulnerabilities, enabling remote code execution for attackers
A critical sandbox escape vulnerability has been disclosed in the popular vm2 Node.js library that, if successfully exploited, could allow attackers to run arbitrary code on the underlying operating system
Critical sandbox escape vulnerability in Grist-Core enables remote code execution via a malicious formula
A critical-severity vulnerability in the vm2 Node.js sandbox library, tracked as CVE-2026-22709, allows escaping the sandbox and executing arbitrary code on the underlying host system. [...]
