Resolves Dependabot alert #265.

Summary

Bumps the transitive dependency ws from 8.18.0 to 8.20.1 to fix GHSA-58qx-3vcg-4xpx / CVE-2026-45736 — uninitialized memory disclosure when a TypedArray is passed as the reason argument to websocket.close().

Analysis

  • ws is a transitive dependency pulled in by jsdom (declared in packages/mql-typescript/package.json as jsdom@^24.1.3).
  • jsdom@24.1.3 declares ws@^8.18.0, which already permits 8.20.1.
  • The lockfile was simply pinned to 8.18.0; running npm update ws --package-lock-only advanced it to the patched 8.20.1 with no manifest changes needed.

Severity

CVSS 3.1 score: 4.4 (Medium). The advisory notes actual severity is believed to be low, as the flaw requires misuse unlikely in practice.

Resolves GHSA-58qx-3vcg-4xpx / CVE-2026-45736 (uninitialized memory
disclosure in ws.close() when a TypedArray is passed as reason).

ws is a transitive dependency of jsdom@^24.1.3, whose declared range
(^8.18.0) already permits 8.20.1. The lockfile entry was updated from
8.18.0 to the patched version via `npm update ws --package-lock-only`.
