Top-level postcss in /website is already on 8.5.12 (#265), but Next.js ships its own copy pinned at 8.4.31 in node_modules/next/node_modules/ postcss/. That nested copy is in the vulnerable range for GHSA-qx2v-qp2m-jg93 / CVE-2026-41305 (XSS via unescaped </style> in CSS Stringify Output). Operationally, exploitability in this project is zero — postcss runs at build time only, processes Tailwind-authored CSS, and no user input ever reaches its stringify path. But the alert is mechanically valid (vulnerable code is in the dependency tree) and Next 16.2.x stable still pins 8.4.31 (only canary 16.3.0+ has the bump). Add an `overrides` entry — same surgical-range style as the existing picomatch and flatted entries — to flatten any vulnerable nested copy to the patched line. After install, the lockfile contains a single postcss instance at 8.5.14 (latest patched) and `npm audit` returns zero vulnerabilities. Verified: `npm run build` succeeds in /website (Next 16.2.5 + Turbopack). Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
