Merged
Conversation
Upgrades next 15.5.9 -> 16.2.6 (fixes 6 Next CVEs incl. DoS / HTTP request smuggling) and @azure/storage-blob 12.29.0 -> 12.29.1 (pulls fast-xml-parser >=5.7.3, fixing 6 CVEs incl. XEE and uncaught exceptions). Adds npm overrides to force-fix transitive deps inside next-auth: preact >=10.28.2 (Critical type-confusion), uuid >=11.1.1, postcss >=8.5.10. tsconfig.json updates are Next 16 codemods. Remaining: leaflet 1.9.4 XSS (no upstream fix available). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Next 16 removed the 'next lint' wrapper, so npm run lint failed in CI with 'Invalid project directory: lint'. Switches the script to 'eslint .' and updates eslint.config.mjs to consume the flat configs that eslint-config-next@16 now exports natively (no FlatCompat). Downgrades three new react-hooks rules (set-state-in-effect, immutability, preserve-manual-memoization) and 'no-require-imports' for scripts/*.js to warnings — these are advisory rules introduced by upgraded plugins, flagging 54 pre-existing patterns that are out of scope for this security PR.
