chore(deps): bump vm2 from 3.9.19 to 3.11.5 in /packages/widgets

[dependabot]

Bumps vm2 from 3.9.19 to 3.11.5.

Release notes

Sourced from vm2's releases.

v3.11.5

What's Changed

Bug fixes

• #566 — Restore util.inspect output on Node 26+. console.log(vm.run(...)) was rendering as Proxy(Proxy({})) / Proxy(Proxy([])) instead of the underlying value. Triggered by Node 26's stricter handling of nested proxies in the inspector.
• #567 — Restore array iteration on vm.freeze()'d host arrays. Calling .map() / .filter() / .forEach() etc. inside the sandbox on a frozen host object containing arrays threw TypeError: 'isExtensible' on proxy: trap result does not reflect extensibility of proxy target. Regression from the 3.11.0 proxy-invariant hardening.
• #568 — Fix .node extension handler key in lib/resolver.js (the key was ' .node' with a leading space, so native addon resolution silently fell through to the default path). Thanks to @​cherr-cc.

Upgrade Notes

Drop-in replacement for 3.11.4. No API or configuration changes.

v3.11.4

Ten advisories closed. Patch release — no API changes for valid configurations.

What's Changed

Security fixes

• GHSA-c4cf-2hgv-2qv6 — Bridge set trap ignoring ECMA-262 §9.5.9 Receiver, letting Object.create(hostObj) children and Reflect.set(hostObj, k, v, custom) writes leak onto the host object (write-channel → RCE).
• GHSA-m5q2-4fm3-vfqp — Cross-realm Symbol.for namespace leak + missing dangerous-symbol guards on the bridge's write traps (set / defineProperty / deleteProperty), enabling sandbox-installed nodejs.util.promisify.custom / stream brand / webstream hooks on host objects (RCE).
• GHSA-v6mx-mf47-r5wg — Host prototype mutation via Function.prototype.{call,apply,bind} and Reflect.{apply,construct} indirection through Object.prototype.__proto__ setter, severing host intrinsic prototype chains and escaping via thisEnsureThis proto-walk fallthrough (RCE).
• GHSA-q3fm-4wcw-g57x — Defense Invariant #11 violation in defaultSandboxPrepareStackTrace (second variant of GHSA-9qj6-qjgg-37qq in a different file): sandbox-installed Array.prototype[N] setter / Array.prototype.join override could observe bridge-internal stack-trace state.
• GHSA-76w7-j9cq-rx2j — Promise species hijack in localPromise's swallow-tail, hijacking the downstream child constructor to capture V8's internal (resolve, reject) capability and reach a raw host-realm error → host Function (RCE).
• GHSA-m4wx-m65x-ghrr — NodeVM constructor patch bypass of GHSA-8hg8-63c5-gwmx: any truthy nesting paired with a non-real-config require produced a NESTING_OVERRIDE-only resolver → inner NodeVM with attacker-chosen require → child_process RCE.
• GHSA-6j2x-vhqr-qr7q — WebAssembly JSPI (WebAssembly.promising / WebAssembly.Suspending, Node 24+ behind a flag, Node 26+ default) producing Promise objects with a host-realm [[Prototype]] chain and no bridge interposition; species hijack delivers a raw host-realm rejection to sandbox .catch → host Function (RCE).
• GHSA-rp36-8xq3-r6c4 — NodeVM builtin denylist bypass via process (whose getBuiltinModule(name) reloads any core module regardless of allow/deny config) and inspector/promises (whose Session().post('Runtime.evaluate', ...) evaluates attacker JS in the host realm). Supersedes GHSA-947f-4v7f-x2v8.
• GHSA-r9pm-gxmw-wv6p — NodeVM builtin: ['*'] wildcard exposing Node's undocumented underscored network builtins (_http_client, _http_server, _tls_*, _stream_*) even when the documented -http/-https/-net/-tls exclusions were used — SSRF-class capability bypass (CVSS 8.6).
• GHSA-9g8x-92q2-p28f — NodeVM builtin allowlist surfacing four process-wide observability builtins (diagnostics_channel, async_hooks, perf_hooks, v8) that read state of the entire host process rather than sandbox-local state — HTTP header / async-context / perf-mark / heap-snapshot exfiltration.

Documentation

• docs/ATTACKS.md extended through Category 35, plus two new Defense Invariants: #12 ("No sandbox-visible object has a host-realm prototype chain without bridge interposition") and #13 ("The NodeVM builtin allowlist is a closed system").

Upgrade Notes

• If you constructed NodeVM({ nesting: <truthy> }) without an explicit require config object, new NodeVM(...) now throws (GHSA-m4wx-m65x-ghrr). This covers every shape that previously silently produced a vm2-only resolver: omitting require, or setting it to any falsy value (false/undefined/null/0/'') or any truthy non-object value (true/number/string/symbol/function); and also any truthy nesting value, not only nesting: true. Either drop nesting, or pass an explicit require config object (e.g. require: { builtin: [] }) to acknowledge that vm2 will be requireable from inside the sandbox. The error message is actionable and links to the README hardening section.
• No other valid configurations are affected. Embedders who explicitly listed any of process / inspector / worker_threads / cluster / vm / repl / module / trace_events / wasi / diagnostics_channel / async_hooks / perf_hooks / v8 in builtin were already running an unsandboxed sandbox; those names now throw at load time and can be re-introduced as safe wrappers via mock / override / SPECIAL_MODULES.

Changelog

Sourced from vm2's changelog.

[3.11.5]

Patch release — no API changes.

Fix

• #566 — util.inspect of vm.run(...) results rendered as Proxy(Proxy({})) on Node 26+. Install nodejs.util.inspect.custom on host-side proxy targets so the inspect output reflects the underlying shape.
• #567 — Array iteration methods on a vm.freeze()-d host array threw an 'isExtensible' on proxy invariant error (regression from the GHSA-grj5-jjm8-h35p species defense). Align the ReadOnly proxy target's extensibility with its trap result and skip species neutralization on the host→sandbox apply path.

[3.11.4]

Ten advisories closed. Patch release — no API changes for valid configurations.

Security fixes

• GHSA-c4cf-2hgv-2qv6 — bridge escape via BaseHandler.set ignoring the ECMA-262 §9.5.9 Receiver argument; Object.create(hostProxy).x = v and Reflect.set(hostProxy, k, v, sandboxObj) wrote through to the host object instead of installing on the receiver, turning every embedder-exposed host object into a sandbox write channel. Receiver-gated install-on-receiver fix in lib/bridge.js mirroring ReadOnlyHandler.set. See ATTACKS.md Category 32 and test/ghsa/GHSA-c4cf-2hgv-2qv6/.
• GHSA-m5q2-4fm3-vfqp — sandbox escape via unblocked cross-realm Symbol.for keys plus missing dangerous-symbol guards on the bridge's write traps. Two-layer structural fix: lib/setup-sandbox.js denies the entire nodejs. namespace at Symbol.for and aligns the read-side filters with the full 9-symbol cache, and lib/bridge.js extends isDangerousCrossRealmSymbol and applies it to the set/defineProperty/deleteProperty traps. See ATTACKS.md Category 8 / Category 20 (both extended) and test/ghsa/GHSA-m5q2-4fm3-vfqp/.
• GHSA-v6mx-mf47-r5wg — host prototype mutation via apply-trap indirection. Sandbox code could reach host prototype-mutating setters (Object.prototype.__proto__, setPrototypeOf, defineProperty, __defineSetter__/__defineGetter__) through Function.prototype.{call,apply,bind} and Reflect.{apply,construct} indirection, sever a host intrinsic's prototype chain, and escape via the bridge's thisEnsureThis proto-walk fallthrough. Two-layer structural fix in lib/bridge.js (apply-trap blocklist + cache check before proto-walk). See ATTACKS.md Category 30 and test/ghsa/GHSA-v6mx-mf47-r5wg/.
• GHSA-q3fm-4wcw-g57x — Defense Invariant #11 hardening for defaultSandboxPrepareStackTrace (second variant of GHSA-9qj6-qjgg-37qq in a different file). The sandbox stack-trace formatter accumulated frames in a sandbox-realm array and .join-ed them, so a sandbox-installed setter on Array.prototype[N] (or .join override) observed bridge-internal state — no host reference reachable today, but one enrichment away from regressing into the GHSA-9qj6 RCE shape. Fixed in lib/setup-sandbox.js by folding frames through a primitive string accumulator (no Array.prototype slot reachable) and converting makeCallSiteGetters to localReflectDefineProperty for symmetry. See ATTACKS.md Category 28 Variant B and test/ghsa/GHSA-q3fm-4wcw-g57x/.
• GHSA-76w7-j9cq-rx2j — Promise species hijack in the localPromise swallow tail. The swallow-tail apply(globalPromisePrototypeThen, this, [...]) call inside localPromise's constructor invoked the cached host Promise.prototype.then without first calling resetPromiseSpecies(this), so a sandbox subclass overriding [Symbol.species] could redirect the downstream child constructor to a user function and capture V8's internal (resolve, reject) capability — delivering a raw host-realm error (RangeError from deep recursion + e.stack) to a sandbox collector and reaching the host Function constructor via .constructor.constructor. One-line fix in lib/setup-sandbox.js adds the missing resetPromiseSpecies(this) before the swallow-tail call, matching the pattern already used by the .then/.catch/Reflect.apply overrides. See ATTACKS.md Category 31 and test/ghsa/GHSA-76w7-j9cq-rx2j/.
• GHSA-m4wx-m65x-ghrr — NodeVM constructor patch bypass of GHSA-8hg8-63c5-gwmx: a truthy nesting paired with anything other than a real require config object produced a NESTING_OVERRIDE-only resolver → inner NodeVM with attacker-chosen require → child_process RCE. Structural fix in lib/nodevm.js: destructure first, then reject at construction whenever nesting is truthy and requireOpts is not a non-null object or Resolver. Supersedes GHSA-8hg8-63c5-gwmx. See ATTACKS.md Category 25 and test/ghsa/GHSA-m4wx-m65x-ghrr/.
• GHSA-6j2x-vhqr-qr7q — sandbox escape via WebAssembly JSPI (Node 24 behind --experimental-wasm-jspi, Node 26+ default). WebAssembly.promising returns Promise objects whose [[Prototype]] chain points directly at the host realm's Promise.prototype with no bridge proxy in between, so p.finally() reaches host Promise.prototype.finally, V8's SpeciesConstructor reads an attacker-controlled p.constructor getter, and the eventual host-realm rejection is dispatched through the attacker's class with no bridge wrapping — e.constructor.constructor('return process')() then evaluates in the host realm. Structural fix in lib/setup-sandbox.js: delete WebAssembly.promising and WebAssembly.Suspending at sandbox bootstrap, mirroring the existing WebAssembly.JSTag removal. Adds Defense Invariant #12 (no sandbox-visible object may have a host-realm prototype chain without bridge interposition). See ATTACKS.md Category 33 and test/ghsa/GHSA-6j2x-vhqr-qr7q/.
• GHSA-rp36-8xq3-r6c4 — NodeVM builtin denylist bypass via process and inspector/promises. The exact-match denylist in lib/builtin.js missed two host-passthrough families: process (whose getBuiltinModule(name) reloads any core module regardless of the embedder's allow/deny configuration) and inspector/promises (whose Session().post('Runtime.evaluate', ...) evaluates attacker JS in the host realm). Structural fix promotes the check to family-prefix via isDangerousBuiltin(key), strips the node: URL prefix, and adds process to the dangerous set — enforced at both BUILTIN_MODULES source and addDefaultBuiltin. Supersedes GHSA-947f-4v7f-x2v8. Adds Defense Invariant #13. See ATTACKS.md Category 21 (extended) and test/ghsa/GHSA-rp36-8xq3-r6c4/.
• GHSA-r9pm-gxmw-wv6p — NodeVM builtin: ['*'] wildcard exposed Node's undocumented underscored network builtins (_http_client, _http_server, the _http_* / _tls_* / _stream_* siblings), letting sandbox code make outbound HTTP requests and open listening sockets even when the documented -http/-https/-net/-tls exclusions were used — SSRF-class capability bypass (CVSS 8.6). Structural fix in lib/builtin.js: BUILTIN_MODULES filter now excludes any name starting with _, so '*' expands only to documented public builtins; explicit opt-in, mock, and override paths remain functional. See ATTACKS.md Category 34 and test/ghsa/GHSA-r9pm-gxmw-wv6p/.
• GHSA-9g8x-92q2-p28f — NodeVM builtin allowlist surfaced four process-wide observability builtins (diagnostics_channel, async_hooks, perf_hooks, v8) that read state from the entire host process rather than the sandbox: HTTP IncomingMessage headers (incl. auth tokens) via diagnostics_channel.subscribe, embedder AsyncLocalStorage context via async_hooks.executionAsyncResource, embedder performance.mark labels via perf_hooks, and the full V8 heap via v8.getHeapSnapshot / v8.queryObjects. Fix in lib/builtin.js: extends DANGEROUS_BUILTINS with the four names, reusing the existing two-layer enforcement (BUILTIN_MODULES filter + addDefaultBuiltin rejection, family-prefix and node:-normalised via isDangerousBuiltin). mock/override escape hatches preserved. See ATTACKS.md Category 35 and test/ghsa/GHSA-9g8x-92q2-p28f/.

Upgrade notes

• If you constructed NodeVM({ nesting: <truthy> }) without an explicit require config object, new NodeVM(...) now throws (GHSA-m4wx-m65x-ghrr). This covers every shape that previously silently produced a vm2-only resolver: omitting require entirely, or setting it to any falsy value (false/undefined/null/0/'') or any truthy non-object value (true/number/string/symbol/function); and also any truthy nesting value, not only nesting: true (1/'yes'/{}/[]/function). Either drop nesting, or pass an explicit require config object (e.g. require: { builtin: [] }) to acknowledge that vm2 will be requireable from inside the sandbox. The error message is actionable and links to the README hardening section.

[3.11.3]

Patch release — no API changes.

Security fix

• GHSA-248r-7h7q-cr24 — async generator yield*-return thenable exception capture. Calling i.return(thenable) on an async generator delegating to a no-return inner iterator let V8's PromiseResolveThenableJob capture synchronous throws from the thenable's .then and surface them to sandbox code as iterator results — bypassing both the transformer's catch instrumentation and the globalPromise.prototype.then rejection sanitiser. Two-layer defense on %AsyncGeneratorPrototype%.next/.return/.throw in lib/setup-sandbox.js: every iterator-result promise routes value and rejection through handleException, and every thenable argument is replaced with a sandbox-realm wrapper whose .then is a fixed safeThen that sanitises sync throws and recursively re-wraps any nested thenable handed to resolve(...). When safeThen reads value.then and it is non-function, the wrapper always resolves with a {__proto__: null} shadow so V8's re-read of .then cannot observe attacker-controlled values — closing every counting/self-replacing-getter TOCTOU variant. Trade-off: identity is not preserved for non-thenable values passed to i.return(x). ATTACKS.md Category 29.

[3.11.2]

Three advisories closed. Patch release — no API changes.

Security fixes

• GHSA-2cm2-m3w5-gp2f — Internal state reachable via computed property access on globalThis. The previous fix (GHSA-wp5r-2gw5-m7q7) tightened the transformer's identifier-rejection but left globalThis['VM2_INTERNAL_STATE_DO_NOT_USE_OR_PROGRAM_WILL_FAIL'] and every reflective probe of the global object (bracket access, Reflect.get, Object.getOwnPropertyDescriptor, Object.getOwnPropertyNames enumeration) returning the live state object — the transformer is a syntactic gate and cannot see through dynamic property keys. Structural fix: the bootstrap script (vm.js's setupSandboxScript source) now declares let VM2_INTERNAL_STATE_DO_NOT_USE_OR_PROGRAM_WILL_FAIL at the script's top level, which lands the binding in the context's [[GlobalLexicalEnvironment]] — reachable as a bare identifier from every script (so transformer-emitted catch handlers still resolve), but absent from globalThis's own-property table (so every computed-key probe returns undefined). The defineProperty install in setup-sandbox.js is removed entirely; the bootstrap IIFE assigns into the outer let instead. Supersedes GHSA-wp5r-2gw5-m7q7's identifier-only mitigation by closing the entire computed-key class. ATTACKS.md Category 27.
• GHSA-9vg3-4rfj-wgcm — Sandbox breakout via null-proto throw / handleException. The post-GHSA-mpf8 hardening switched handleException and globalPromise.prototype.then onFulfilled to wrap caught/resolved values with bridge.from() for "symmetry". from() builds a sandbox-side proxy whose target the bridge treats as host-realm; calling it on a sandbox-realm null-proto value ({__proto__: null} thrown or Promise.resolve-d by sandbox JS) produced a proxy whose set trap unwrapped sandbox proxies of host references (e.g. Buffer.prototype.inspect) back to their raw host originals and stored them on the underlying sandbox object — readable via the original sandbox reference and pivot to host Function constructor → RCE. Three callsites in lib/setup-sandbox.js reverted to ensureThis() semantics; the host-Promise rejection sanitizer composes from() outside handleException so the GHSA-mpf8 invariant (host null-proto rejection values must reach sandbox callbacks bridge-wrapped) is preserved. ATTACKS.md Category 26.
• GHSA-9qj6-qjgg-37qq — sandbox breakout via the species-defense helper neutralizeArraySpeciesBatch. The helper appended saved-state records to a fresh [] literal that — being allocated by the sandbox-side bridge closure — inherited sandbox Array.prototype. A sandbox-installed setter on Array.prototype[N] therefore captured the next saved[saved.length] = c write and exposed c.arr (a host-realm proxy) directly to attacker code, leading to host Function extraction and RCE. Fixed in lib/bridge.js by writing every saved-state entry through thisReflectDefineProperty so the appended slot is an own data property and no Array.prototype[N] setter is ever invoked while the bridge holds raw saved state. ATTACKS.md gains a new Defense Invariant ("Bridge-internal containers must not invoke sandbox code") codifying the cross-cutting principle.

Note

Low Risk
Dev-only transitive lockfile bump with no direct product code changes; lowers exposure to known vm2 sandbox escape advisories without changing runtime behavior in shipped widgets.

Overview
Updates packages/widgets/package-lock.json only: vm2 3.9.19 → 3.11.5 (transitive via @builder.io/react, dev dependency). acorn is bumped 8.14.0 → 8.17.0 as vm2’s dependency range now expects ^8.15.0.

No application or build config changes in this diff—just the lockfile resolution for the sandbox library and its parser dependency.
