CVE-2026-44001

vm2 is an open source vm/sandbox for Node.js. Prior to 3.11.0, 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....

FlowiseAI: Authenticated Host RCE via POST /api/v1/node-custom-function and NodeVM Sandbox Escape

Summary POST /api/v1/node-custom-function lacks route-level authorization, allowing any authenticated user or API key to submit arbitrary JavaScript to the Custom JS Function node. When E2BAPIKEY is not configured — the common deployment case — Flowise executes this code inside a NodeVM sandbox...

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...

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 through the proxy trap methods in createBridge in the bridge handler code. An attacker can leak a handler...
