CVE-2026-26956

A flaw was found in vm2, an open-source sandbox for Node.js. An attacker can exploit this vulnerability by running malicious code within the VM.run() function, allowing them to escape the sandbox and gain access to the host process. This can lead to arbitrary code execution on the host system, enabling the attacker to run host commands without any host cooperation.
