- record dependency chains, exposure analysis, and remediation options for Dependabot alert #200 (GHSA-vfj7-8cjw-p6xm / CVE-2026-93687) - no installable fix exists: braces@3.0.3 is the latest npm release and the upstream maintainer disputes the report - the vulnerable codepath is unreachable from any runtime/build input this app accepts; permanent fix requires migrating off react-scripts - references Dependabot alert #200

Summary
Addresses Dependabot alert #200 for
braces(GHSA-vfj7-8cjw-p6xm / CVE-2026-93687) by recording the dependency chains, exposure analysis, and remediation options inSECURITY.md.Why this is a docs-only change
bracesversion exists. The latest npm release is3.0.3(published 2024-05-21), which is itself the vulnerable version. The upstream maintainer has publicly disputed the report and has not tagged a fix.first_patched_versionisnullper the advisory, so a direct dep bump, transitive override, or Dependabot auto-PR cannot resolve the alert.react-scriptsis no longer maintained). That is a substantial project change outside the scope of a Dependabot fix.Dependency chains (verified via
npm ls braces --all)Both chains resolve through
react-scripts.micromatch@4.0.8(latest) still hard-depends onbraces: ^3.0.3, so chain 1 cannot be closed by bumping micromatch. Forcingchokidar@^4(which no longer depends onbraces) does not eliminatebracesfrom the tree (chain 1 remains) and risks breakingreact-scripts/webpack-dev-serverintegration, so it is intentionally omitted.Exposure analysis
bracesis reached only through CRA's static internal config:eslint-webpack-plugin→micromatch→bracesfor the hard-coded ESLint file-glob patterns inreact-scripts' webpack config.chokidar→bracesfor file-watch globs from CRA/tailwindcss.No code path accepts attacker-controlled input and forwards it to
braces.compile()/expand(). The vulnerable codepath (deeply nested brace patterns under the 10,001-character limit) is therefore not reachable from any runtime or build-time input this app accepts.Alert state
openafter this PR merges. There is no automated resolution path whilebraceshas no patched release.bracesrelease ships (or a maintained fork becomes standard), orreact-scriptsis replaced by an actively maintained bundler.Verification
npm install— clean, no errors (deprecation warnings only).npm run build—Compiled successfully., production bundle produced inbuild/.SECURITY.mdadded.
