Arbitrary Code Injection

Overview org.webjars.npm:vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Arbitrary Code Injection despite the recently introduced neutralizeArraySpeciesBatch helper in lib/bridge.js. An attacker can execute...

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,...

vm2 has a Sandbox Escape via Promise Constructor Unhandled Rejection (Process Crash DoS)

Summary A sandbox escape vulnerability in vm2 v3.10.5 allows any sandboxed code to crash the host Node.js process via a single Promise constructor that triggers an unhandled rejection propagating to the host. The fix for CVE-2026-22709 v3.10.2 only sanitized the onRejected callback in .then and...
