On a case-insensitive filesystem (macOS APFS/HFS+, Windows NTFS) a write to `.ESLINTRC.JS` lands on the exact same inode as `.eslintrc.js`, but the guard looked the basename up in PROTECTED_FILES with a case-sensitive `Set.has`. Every entry in that Set is lowercase, so any case-variant path missed the branch entirely and returned exit 0 — a single Write silently overwrote a live config while the hook reported success. Reproduced on macOS APFS: `.eslintrc.js` and `.ESLINTRC.JS` share one inode, yet the hook returned exit 2 for the former and exit 0 for the latter, and the uppercase write replaced the real config's contents. This is a one-step bypass of the whole guard and needs no shell access, unlike the known delete-then-recreate route. Fix: also test `basename.toLowerCase()`. All 32 PROTECTED_FILES entries are already lowercase, so the fallback is exact. On a genuinely case-sensitive filesystem this costs at most a false positive on a distinct file whose name differs from a protected one by case alone. Behaviour deliberately unchanged: first-time creation is still allowed (the bootstrap affordance), non-config paths still pass through, and the existing lstat/ENOENT fail-closed semantics are untouched. Test: adds a case-variant case that asserts exit 2. It guards itself with an inode comparison and skips on case-sensitive filesystems rather than asserting something untrue there. Verified in both directions — it FAILS against the unpatched hook (`Got 0; 0 !== 2`) and passes with the fix. Suite: 9/9. |
