CVE-2026-92950 vm2 before 3.11.7 Sandbox Escape via CLI require

vm2 before 3.11.7 contains a sandbox escape vulnerability in the CLI tool that allows attackers to execute arbitrary code in the host Node.js process. Attackers can supply a malicious script file to the vm2 CLI that uses requirefilename to re-execute itself in the host realm, bypassing sandbox...

CVE-2026-92950

vm2 before 3.11.7 contains a sandbox escape in its CLI tool . By supplying a malicious script file that calls require(__filename), an attacker re-executes the script in the host Node.js realm , breaking sandbox isolation and gaining access to host modules such as fs and child_process . This yield...
