CVE-2026-92949

A flaw was found in vm2, a JavaScript sandbox. This vulnerability allows sandboxed scripts to bypass security protections, specifically vm.freeze and vm.readonly, which are designed to prevent unauthorized modifications to objects. An attacker can exploit this by directly accessing and invoking...

CVE-2026-92958

A flaw was found in vm2, a sandbox for Node.js. When the NodeVM embedder uses a builtin wildcard with negative entries to deny specific modules, such as 'fs' for file system access, the denylist mechanism fails to block subpaths like 'fs/promises'. This allows sandboxed code to bypass the intende...

Critical Docker Sandboxes Flaw Lets Malicious Guest Code Read and Modify macOS Host Files

Malicious code running inside a Docker Sandboxes virtual machine on macOS could escape the project directory shared into it and read or change files anywhere else on the host, Docker warns in a security announcement on September 15. The escape runs with the rights of the host account that runs th...

CVE-2026-92959

A flaw was found in vm2, a JavaScript sandbox. This vulnerability allows a sandboxed script to bypass security restrictions designed to prevent asynchronous code execution. An attacker can exploit this by using specific Promise methods to assimilate malicious 'thenables,' enabling code to run...

CVE-2026-92952

A flaw was found in vm2. The vm2 sandbox incompletely filters Node.js internal symbols, specifically nodejs.stream.disturbed and nodejs.stream.errored, across the sandbox boundary. This allows code running within the sandbox to obtain real host symbols and use them to corrupt the host-visible...

CVE-2026-92960

vm2 before 3.11.6 fails to restrict access to os and dns builtins under the builtin: '' configuration, allowing sandbox code to read host process identity and network topology. Attackers can invoke dns.setServers to hijack the host process DNS resolver globally, redirecting all subsequent host DN...

CVE-2026-92963

vm2 versions before 3.11.2 fail to properly restrict access to the VM2INTERNALSTATEDONOTUSEORPROGRAMWILLFAIL global variable. Attackers can access this internal state object through globalThis to retrieve sensitive sandbox internals...

CVE-2026-92956

vm2 versions 3.10.1 through 3.11.6 contain a sandbox escape reachable from a default new VM sandbox when running on Node.js 26. WebAssembly.compileStreaming and WebAssembly.instantiateStreaming can produce a raw host-realm Promise that rejects with a host-realm error object; by controlling...

CVE-2026-92953

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-2026-92955

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-2026-92950

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-2026-92952

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-2026-92948

vm2 versions = 3.9.6 and therefore executes arbitrary JavaScript in an unrestricted host Node process outside the NodeVM sandbox. Fixed in vm2 3.11.7...

CVE-2026-92949

vm2 versions from 3.9.6 before 3.11.7 fail to properly restrict access to accessor properties on frozen objects, allowing sandboxed scripts to bypass vm.freeze and vm.readonly protections. Attackers can use Object.getOwnPropertyDescriptor or lookupSetter to extract and invoke host object setters...

CVE-2026-92940

vm2 versions 3.11.3 through 3.11.6 expose the host process's real https.globalAgent to sandboxed code when a NodeVM is explicitly configured to allow require'https'. The builtin loader wraps host modules in a read-only proxy, but method calls such as Agent.prototype.on are forwarded to the...

CVE-2026-92944

vm2 versions 3.10.2 through 3.11.6 contain a sandbox escape vulnerability on Node.js 26 where Promise.prototype.finally bypasses vm2's wrapper protections due to a stale PromiseThenLookupChain protector in V8 14.6. Attackers can exploit this by creating an async function that returns a Promise wi...

CVE-2026-92938

vm2 versions 3.11.3 through 3.11.6 expose Node.js's host node:sqlite module to code running in NodeVM when that builtin is permitted, either explicitly or through builtin: ''. The module is wrapped with vm.readonly, which prevents property assignment but leaves host-authority callables reachable;...

CVE-2026-92937

vm2 3.11.6 is vulnerable to a sandbox escape leading to remote code execution in the host Node.js process. The fix for GHSA-m283-3h24-438v is incomplete: the bridge gate at lib/bridge.js:1624 identity-checks only the direct call target when deciding whether to rebuild/sanitise a rejected host...

CVE-2026-92939

vm2 3.11.3 through 3.11.6 exposes the host Node.js crypto module to a NodeVM sandbox when the crypto builtin is allowed. The module is presented via a recursive read-only proxy, but its callable exports still execute with host-process authority. Sandboxed JavaScript can therefore call...

CVE-2026-92935

vm2 is a sandbox for running untrusted Node.js code. In versions = 3.11.4 and = 3.11.6, the NodeVM constructor computes hasRealRequireConfig with typeof requireOpts === 'object' && requireOpts !== null, so an array-shaped require value for example require: satisfies the guard that is meant to...
