GHSA-98XX-8MX4-X7CM vm2 NodeVM can replace the host process TLS trust store

Summary vm2 3.11.6 exposes the host tls module to a NodeVM when that builtin is explicitly allowed. Although the module object is wrapped as read-only, its functions still execute against process-wide host state. On Node.js versions that provide tls.setDefaultCACertificates, sandbox code can...

The vulnerability of the LegacyResolver.customResolve() function in the lib/resolver-compat.js file, a part of the NodeVM library, within the vm2 package manager of NPM, allows a malicious actor to execute arbitrary code.

The vulnerability of the LegacyResolver.customResolve function in the lib/resolver-compat.js file of the NodeVM library’s vm2 module is related to authentication process vulnerabilities. Exploiting this vulnerability could allow an attacker to execute arbitrary code...

CVE-2026-92960

A flaw was found in vm2. In configurations allowing built-in modules, vm2 fails to restrict access to the host operating system and Domain Name System DNS modules. An attacker who can execute code inside the sandbox can exploit this flaw to hijack the host process DNS resolver, redirecting outbou...

CVE-2026-92957

A flaw was found in vm2. Untrusted code running within the sandbox can bypass module restriction policies to achieve arbitrary code execution on the underlying host. Due to improper normalization of module names containing the node: prefix, deny-list rules fail to prevent access to sensitive...

CVE-2026-92956

A flaw was found in vm2. When running untrusted code within a sandbox, improper isolation in WebAssembly streaming functions allows host error objects to leak into the sandbox environment. An attacker capable of running code inside the sandbox can exploit this flaw to escape sandbox containment a...

CVE-2026-92954

A flaw was found in vm2. An attacker capable of running untrusted code within the sandbox can trigger a Denial of Service DoS by causing the host application process to terminate. This vulnerability exists because asynchronous operations Promises returned from the host environment are not properl...

CVE-2026-92953

A flaw was found in vm2. The sandbox fails to properly isolate host object structures from untrusted code running inside the virtual machine. An attacker can exploit this issue by manipulating object prototype chains to modify shared host prototypes, resulting in prototype pollution the...

CVE-2026-92951

A flaw was found in vm2. The external package allowlist improperly validates package names using substring matching rather than exact name boundaries. An attacker capable of running code within the sandbox can exploit this issue by requesting a package name containing an allowlisted substring,...

CVE-2026-92950

A flaw was found in vm2. An attacker can achieve arbitrary code execution on the host system by escaping sandbox isolation through the command-line interface CLI tool. By supplying a malicious script that uses the require function to re-execute itself within the host environment, untrusted code c...

CVE-2026-92947

A flaw was found in vm2. The sandbox environment inadvertently exposes the host system's shared memory buffer pool to sandboxed code. An attacker running untrusted code inside the sandbox can access and modify these shared buffers, resulting in unauthorized information disclosure of host memory o...

CVE-2026-92946

A flaw was found in vm2. This vulnerability allows an attacker executing untrusted code within the sandbox to escape isolation and achieve arbitrary code execution on the host system. When external module loading is permitted without restricting access to dependency directories, sandboxed code ca...
