vm2: timeout Option Bypass via FinalizationRegistry Cleanup Callback (Unbounded Host Event-Loop Block)

Vulnerability Summary vm2's VM timeout option is documented and relied upon as the mechanism that bounds how long sandboxed code may execute. In the current implementation, the timeout only wraps the single synchronous call to VMrun via doWithTimeout → this.runScriptscript in lib/vm.js. It does...

Denial of Service (DoS)

Overview vm2 is a sandbox that can run untrusted code with whitelisted Node's built-in modules. Affected versions of this package are vulnerable to Denial of Service DoS through the FinalizationRegistry process. An attacker can cause the host event loop to be blocked for an unbounded period by...

CVE-2026-92942: Uncontrolled Resource Consumption

vm2 before 3.11.7 affected versions = 3.11.6 does not enforce the VM timeout option on code executed outside the synchronous VMrun call. The timeout only wraps the single call to runScript via doWithTimeout in lib/vm.js, and FinalizationRegistry and WeakRef are exposed to sandboxed code unmodifie...
