Summary

Hono 4.13.5 fixes query parsing that could read parameters after a URL fragment, creating cache-key and proxy interpretation differentials. It also closes a toSSG path-normalisation gap that could write outside the output directory and bounds dot-notation expansion in parseBody() to prevent memory exhaustion.

Why it matters

These issues affect web applications deployed behind proxies, WAFs or static-site pipelines, so maintainers should treat the patch as an upgrade rather than a routine bugfix.
