browserstack-runner vulnerable to Remote Code Execution via vm sandbox escape in _log HTTP handler

Summary The HTTP handler /log in lib/server.js lines 491–515 of browserstack-runner passes unauthenticated user-supplied data to vm.runInNewContext combined with eval, enabling a sandbox escape and arbitrary code execution on the host system. Details When browserstack-runner starts, it creates an...

CVE-2026-45102

CVE-2026-45102 concerns OneUptime, an open-source monitoring platform. Prior to version 10.0.98, OneUptime used Node.js vm module as an isolation primitive, which is not intended for security boundaries and can be escaped via error objects and infinite recursion, potentially enabling remote code ...

Arbitrary Code Injection

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 Arbitrary Code Injection through lib/builtin.js. An attacker can execute host code when the allowlist includes -X or uses and then calls...

Information Disclosure

Node.js is vulnerable to Information Disclosure. The vulnerability is due to improper buffer allocation handling when using the vm module with the timeout option, where interrupted allocations may return buffers containing uninitialized memory, potentially exposing leftover data such as tokens or...

OneUptime:: node:vm sandbox escape in probe allows any project member to achieve RCE

Summary OneUptime lets project members write custom JavaScript that runs inside monitors. The problem is it executes that code using Node.js's built-in vm module, which Node.js itself documents as "not a security mechanism — do not use it to run untrusted code." The classic one-liner escape gives...

CVE-2026-27574

OneUptime is a solution for monitoring and managing online services. In versions 9.5.13 and below, custom JavaScript monitor feature uses Node.js's node:vm module explicitly documented as not a security mechanism to execute user-supplied code, allowing trivial sandbox escape via a well-known...

nodejs: Nodejs uninitialized memory exposure

A memory exposure flaw has been discovered in Node.js. A flaw in Node.js's buffer allocation logic can expose uninitialized memory when allocations are interrupted, when using the vm module with the timeout option. Under specific timing conditions, buffers allocated with Buffer.alloc and other...

CVE-2026-25533

Enclave is a secure JavaScript sandbox designed for safe AI agent code execution. Prior to 2.10.1, the existing layers of security in enclave-vm are insufficient: The AST sanitization can be bypassed with dynamic property accesses, the hardening of the error objects does not cover the peculiar...

Infinite loop

Overview @enclave-vm/core is a Sandbox runtime for secure JavaScript code execution Affected versions of this package are vulnerable to Infinite loop via infinite recursion in the vm module. An attacker can execute arbitrary code outside the intended sandbox by crafting recursive calls that explo...

Sandbox escape via infinite recursion and error objects

Note: The npm package has moved to @enclave-vm/core formerly enclave-vm. All fixed versions and guidance refer to @enclave-vm/core. Summary The existing layers of security in enclave-vm are insufficient: The AST sanitization can be bypassed with dynamic property accesses, the hardening of the err...

Race Condition

Overview Affected versions of this package are vulnerable to Race Condition in the vm module with the timeout option. An attacker can access secrets like tokens or passwords to leak or cause data corruption by exploiting a race condition in buffer allocation logic that allows zero-fill toggle to...
