CVE-2026-49143

BrowserStack Runner through 0.9.5 contains a remote code execution vulnerability in the /log HTTP handler that allows unauthenticated network-adjacent attackers to execute arbitrary code by submitting crafted JSON request bodies to the handler, which passes user-supplied data to vm.runInNewContex...

CVE-2026-49143

CVE-2026-49143 affects BrowserStack Runner up to version 0.9.5. The vulnerability is in the /_log HTTP handler, permitting unauthenticated, network-adjacent attackers to achieve remote code execution by sending crafted JSON bodies that are passed to vm.runInNewContext() with eval(); attackers can...

Incomplete List of Disallowed Inputs

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 Incomplete List of Disallowed Inputs via the builtin allowlist handling in lib/builtin.js. An attacker can reach host code by requiri...

GHSA-6J2X-VHQR-QR7Q vm2 sandbox escape via JSPI-backed Promise `.finally()` species bypass

Summary A sandbox escape vulnerability in vm2 allows arbitrary code execution in the host process when untrusted code is executed with async support on runtimes exposing WebAssembly JSPI WebAssembly.promising / WebAssembly.Suspending. In the tested configuration, a JSPI-backed Promise can reach...

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...

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,...

GHSA-FFH4-J6H5-PG66 VM2 Has a WASM Sandbox Escape (Node 25 only)

Summary Full sandbox escape with arbitrary code execution. Attacker code inside VM.run obtains host process object and runs host commands with zero host cooperation. Details Confirmed on: vm2 3.10.4, Node.js v25.6.1 x64 Linux Trigger: Attacker-controlled code passed to VM.run Requires: Node.js...

VM2 Has Sandbox Breakout Through Promise Species

Summary The fix for https://github.com/patriksimek/vm2/security/advisories/GHSA-cchq-frgv-rjh5 is insufficient and can be circumvented allowing attackers to write code which can escape from the VM2 sandbox and execute arbitrary commands on the host system. Details The fix for...

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 the vm2.run function. An attacker can execute arbitrary commands on the host system by escaping the sandbox...
