JLSEC-2026-655 Deno: Permission Bypass via Unicode Normalization Mismatch on macOS (APFS)

Summary Deno's permission system enforces filesystem and execution restrictions by comparing the requested path against the path supplied to --deny-read, --deny-write, --deny-run, or --deny-ffi. On macOS, that comparison was done at the raw-byte level while the APFS filesystem treats different...

Arbitrary HTML present after sanitization because of unicode normalization

ImpactIf using keeptypographicwhitespace=False which is the default, the sanitizer normalizes unicode to the NFKC form at the end. Some unicode characters normalize to chevrons; this allows specially crafted HTML to escape sanitization. PatchesThe problem has been fixed in 2.4.2. WorkaroundsSet...
