4.12.4

Security fixes

This release includes fixes for the following security issues:

SSE Control Field Injection

Affects: streamSSE() in Streaming Helper. Fixes injection of unintended SSE fields by rejecting CR/LF characters in event, id, and retry. https://github.com/honojs/hono/security/advisories/GHSA-p6xx-57qc-3wxr

Cookie Attribute Injection in setCookie()

Affects: setCookie() from hono/cookie. Fixes cookie attribute manipulation by rejecting ;, \r, and \n in domain and path options. https://github.com/honojs/hono/security/advisories/GHSA-5pq2-9x2x-5p6w

Middleware Bypass in Serve Static

Affects: Serve Static middleware. Fixes inconsistent URL decoding that could allow protected static resources to be accessed without triggering route-based middleware. https://github.com/honojs/hono/security/advisories/GHSA-q5qw-h33p-qvwr

Users who uses Strreaming Helper, Cookie utility, and Serve Static are strongly encouraged to upgrade to this version.
