Updates lodash from 4.17.21 to 4.18.1

Release notes

Sourced from lodash's releases.

4.18.1

Bugs

Fixes a ReferenceError issue in lodash lodash-es lodash-amd and lodash.template when using the template and fromPairs functions from the modular builds. See lodash/lodash#6167

These defects were related to how lodash distributions are built from the main branch using https://github.com/lodash-archive/lodash-cli. When internal dependencies change inside lodash functions, equivalent updates need to be made to a mapping in the lodash-cli. (hey, it was ahead of its time once upon a time!). We know this, but we missed it in the last release. It's the kind of thing that passes in CI, but fails bc the build is not the same thing you tested.

There is no diff on main for this, but you can see the diffs for each of the npm packages on their respective branches:

4.18.0

v4.18.0

Full Changelog: lodash/lodash@4.17.23...4.18.0

Security

_.unset / _.omit: Fixed prototype pollution via constructor/prototype path traversal (GHSA-f23m-r3pf-42rh, fe8d32e). Previously, array-wrapped path segments and primitive roots could bypass the existing guards, allowing deletion of properties from built-in prototypes. Now constructor and prototype are blocked unconditionally as non-terminal path keys, matching baseSet. Calls that previously returned true and deleted the property now return false and leave the target untouched.

_.template: Fixed code injection via imports keys (GHSA-r5fr-rjxr-66jc, CVE-2026-4800, 879aaa9). Fixes an incomplete patch for CVE-2021-23337. The variable option was validated against reForbiddenIdentifierChars but importsKeys was left unguarded, allowing code injection via the same Function() constructor sink. imports keys containing forbidden identifier characters now throw "Invalid imports option passed into _.template".

lodash.* modular packages

Diff

We have also regenerated and published a select number of the lodash.* modular packages.

These modular packages had fallen out of sync significantly from the minor/patch updates to lodash. Specifically, we have brought the following packages up to parity w/ the latest lodash release because they have had CVEs on them in the past:

Updates node-forge from 1.3.1 to 1.4.0

Changelog

Sourced from node-forge's changelog.

1.4.0 - 2026-03-24

Security

  • HIGH: Denial of Service in BigInteger.modInverse()
    • A Denial of Service (DoS) vulnerability exists due to an infinite loop in the BigInteger.modInverse() function (inherited from the bundled jsbn library). When modInverse() is called with a zero value as input, the internal Extended Euclidean Algorithm enters an unreachable exit condition, causing the process to hang indefinitely and consume 100% CPU.
    • Reported by Kr0emer.
    • CVE ID: CVE-2026-33891
    • GHSA ID: GHSA-5gfm-wpxj-wjgq
  • HIGH: Signature forgery in RSA-PKCS due to ASN.1 extra field.
    • RSASSA PKCS#1 v1.5 signature verification accepts forged signatures for low public exponent keys (e=3). Attackers can forge signatures by stuffing "garbage" bytes within the ASN.1 structure in order to construct a signature that passes verification, enabling Bleichenbacher style forgery. This issue is similar to CVE-2022-24771, but adds bytes in an addition field within the ASN.1 structure, rather than outside of it.
    • Additionally, forge does not validate that signatures include a minimum of 8 bytes of padding as defined by the specification, providing attackers additional space to construct Bleichenbacher forgeries.
    • Reported as part of a U.C. Berkeley security research project by:
      • Austin Chu, Sohee Kim, and Corban Villa.
    • CVE ID: CVE-2026-33894
    • GHSA ID: GHSA-ppp5-5v6c-4jwp
  • HIGH: Signature forgery in Ed25519 due to missing S < L check.
    • Ed25519 signature verification accepts forged non-canonical signatures where the scalar S is not reduced modulo the group order (S >= L). A valid signature and its S + L variant both verify in forge, while Node.js crypto.verify (OpenSSL-backed) rejects the S + L variant, as defined by the specification. This class of signature malleability has been exploited in practice to bypass authentication and authorization logic (see CVE-2026-25793, CVE-2022-35961). Applications relying on signature uniqueness (i.e., dedup by signature bytes, replay tracking, signed-object canonicalization checks) may be bypassed.
    • Reported as part of a U.C. Berkeley security research project by:
      • Austin Chu, Sohee Kim, and Corban Villa.
    • CVE ID: CVE-2026-33895
    • GHSA ID: GHSA-q67f-28xg-22rw
  • HIGH: basicConstraints bypass in certificate chain verification.
    • pki.verifyCertificateChain() does not enforce RFC 5280 basicConstraints requirements when an intermediate certificate lacks both the basicConstraints and keyUsage extensions. This allows any leaf certificate (without these extensions) to act as a CA and sign other certificates, which node-forge will accept as valid.
    • Reported by Doruk Tan Ozturk (@​peaktwilight) - doruk.ch
    • CVE ID: CVE-2026-33896
    • GHSA ID: GHSA-2328-f5f3-gj25

Updates vm2 from 3.11.3 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.

Full Changelog: patriksimek/vm2@v3.11.4...v3.11.5

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.

Full Changelog: patriksimek/vm2@v3.11.3...v3.11.4

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.
