Duplicate Advisory: vm2: NodeVM builtin denylist bypass via fs/promises despite -fs, allowing host filesystem writes

Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-6rh5-qq4q-97xh. This link is maintained to preserve external references. Original Description vm2 through 3.11.6 contains a builtin-module denylist bypass in NodeVM. When the embedder uses the builtin wildcard...

CVE-2026-92933

A flaw was found in vm2. The NodeVM component exposes the host util module, including the util.getCallSites function, to the sandbox as an unfiltered copy. On Node.js versions 22.9 and later, this allows sandboxed code to access util.getCallSites, which can return the host process's full call...

CVE-2026-92958

vm2 through 3.11.6 contains a builtin-module denylist bypass in NodeVM. When the embedder uses the builtin wildcard together with negative entries e.g. require: builtin: '', '-fs', '-childprocess' , negative entries are matched by exact module name in lib/builtin.js, so -fs removes only the built...

CVE-2026-92955

vm2 before 3.11.8 contains a sandbox escape vulnerability in NodeVM that allows attackers to access the host proto getter/setter through console.stdout and console.stderr. Attackers can overwrite EventEmitter.prototype.emit and trigger process events to execute code with process context, bypassin...

CVE-2026-92941

vm2 versions from 3.11.3 before 3.11.7 expose the host tls module to NodeVM sandbox code, allowing attackers to call tls.setDefaultCACertificates and replace process-wide certificate authorities. Attackers with access to allowed tls and url builtins can use URLSearchParams to create host-realm...

CVE-2026-92946

vm2 before 3.11.7 contains a remote code execution vulnerability when require.external is enabled without an explicit require.root that excludes nodemodules. Sandboxed code can require vm2's own package, instantiate an unrestricted NodeVM instance, and execute arbitrary host OS commands via...

EUVD-2026-81608

vm2 before 3.11.8 does not fully enforce the allowAsync: false option in VM and NodeVM. While localPromise.prototype.then is replaced with a handler that throws 'Async not available', the sandbox's Promise static methods Promise.resolve, Promise.all, Promise.race, Promise.any, and...

CVE-2026-92958 vm2 before 3.11.7 Denylist Bypass via fs/promises

CVE-2026-92958

vm2 (a Node.js sandboxing library) versions through 3.11.6 contain a builtin-module denylist bypass in NodeVM . When embedders use the wildcard with negative entries (e.g., -fs), matching is done by exact module name in lib/builtin.js, so fs/promises is not blocked. Sandboxed code can therefore c...

CVE-2026-92957

vm2 (a Node.js sandboxing library) through version 3.11.6 fails to normalize node:-prefixed builtin specifiers when matching negative entries in a NodeVM wildcard require policy. Because deny-list entries are compared by exact string against canonical builtin names, a policy like ['*', '-node:chi...

CVE-2026-92957 vm2 before 3.11.7 NodeVM Builtin Deny-List Bypass via node: Prefix

vm2 through 3.11.6 does not normalize node:-prefixed builtin specifiers when evaluating user-supplied negative deny entries in a NodeVM wildcard require policy. Although NodeVM strips the node: prefix during require resolution, negative wildcard entries are matched by exact string comparison...
