CVE-2026-92954

vm2 is a Node.js sandbox library for running untrusted JavaScript. In versions 3.10.0 through 3.11.7 , Promises returned from the host realm into the sandbox are not marked as handled at the bridge boundary. Only sandbox-created Promises receive a rejection-swallowing wrapper, and host-side rejec...

CVE-2026-92953 vm2 3.11.0 through 3.11.7 Prototype Pollution via TypedArray

vm2 versions from 3.11.0 before 3.11.8 fail to protect host TypedArray and ArrayBuffer prototypes from sandbox mutation. Attackers can use prototype-walking primitives to reach and modify host Uint8Array.prototype, %TypedArray%.prototype, and ArrayBuffer.prototype, causing host-created typed arra...

CVE-2026-92953

vm2 (a Node.js sandboxing library) versions 3.11.0 through 3.11.7 fail to protect host TypedArray and ArrayBuffer prototypes from sandbox mutation. An attacker inside the sandbox can use prototype-walking primitives to reach and modify Uint8Array.prototype , %TypedArray%.prototype , and ArrayBuff...

CVE-2026-92952 vm2 3.11.4 through 3.11.6 Sandbox Symbol Filtering Bypass

vm2 versions 3.11.4 through 3.11.6 incompletely filter Node.js registered internal symbols across the sandbox boundary. The extraction filters in lib/setup-sandbox.js and the cross-realm symbol checks and write traps in lib/bridge.js use a fixed list of known dangerous registered symbols that omi...

CVE-2026-92951 vm2 before 3.11.7 Module Allowlist Bypass via Custom Resolver

vm2 before 3.11.7 contains an incorrect authorization vulnerability in the external package allowlist check that uses non-exact substring matching instead of full package-name boundary validation. Attackers can bypass the allowlist by requiring a colliding package name that contains an allowliste...

CVE-2026-92950

vm2 before 3.11.7 contains a sandbox escape in its CLI tool . By supplying a malicious script file that calls require(__filename), an attacker re-executes the script in the host Node.js realm , breaking sandbox isolation and gaining access to host modules such as fs and child_process . This yield...

CVE-2026-92950 vm2 before 3.11.7 Sandbox Escape via CLI require

vm2 before 3.11.7 contains a sandbox escape vulnerability in the CLI tool that allows attackers to execute arbitrary code in the host Node.js process. Attackers can supply a malicious script file to the vm2 CLI that uses requirefilename to re-execute itself in the host realm, bypassing sandbox...

CVE-2026-92951

vm2 prior to version 3.11.7 is affected by an incorrect authorization flaw in its external package allowlist mechanism. The root cause is the use of non-exact substring matching instead of full package-name boundary validation, allowing an attacker to require a colliding package name that merely ...
