chore: Remediate 3 Dependabot security alerts - #253
Merged
Conversation
Remove react-router-dom (^6.30.4) from devDependencies to remediate three open Dependabot security alerts: - GHSA-wrjc-x8rr-h8h6 (CVE-2026-53669): react-router open redirect - GHSA-jjmj-jmhj-qwj2 (CVE-2026-53668): react-router-dom open redirect/XSS - GHSA-337j-9hxr-rhxg (CVE-2026-53666): react-router constructor injection react-router-dom v7 (the first patched line) requires react >= 18, but this package pins react ^16.14.0, so an upgrade is not viable. The dependency is dropped instead, following the same approach taken in cloudscape-design/build-tools#74. test-pages/src/index.tsx used only BrowserRouter + Routes + Route + Link for navigating between three dev-harness pages. This is replaced with a ~30-line hand-rolled router using window.location.pathname, useState, and a popstate listener — no new dependencies. URL structure is preserved: /focus-visible.page and /use-resize-observer-test continue to resolve exactly as before, keeping integration tests green. Lockfile delta: -3 entries (react-router-dom@6.30.4, react-router@6.30.4, @remix-run/router@1.23.3). No entries added. No non-dev dependency versions changed, so NPMPM check scope is empty.

Summary
Removes
react-router-domfromdevDependenciesand replaces its usage intest-pages/src/index.tsxwith a minimal hand-rolled pathname router. This closes all 3 open Dependabot security alerts. There are no auto-generated Dependabot PRs for these alerts; this is the sole gap PR.Alerts addressed by this PR
All three alerts share the same root cause:
react-router-dom@6.30.4and its transitivereact-router@6.30.4.Direct alert links (verbatim from Dependabot alerts API):
Merging this PR clears all 3 gap alerts this PR covers.
Why not upgrade?
first_patched_version: nullfor the 6.x line — no patched 6.x version exists.react-router >= 7.18.0(different major line).react-router-dom@7requiresreact >= 18; this package pinsreact ^16.14.0, so a v7 upgrade forces a React major bump — same constraint resolved by removing the dep in build-tools#74.What changed
