chore(deps): bump hono from 4.12.28 to 4.12.34

[dependabot]

Bumps hono from 4.12.28 to 4.12.34.

Release notes

Sourced from hono's releases.

v4.12.34

Security fixes

This release includes fixes for the following security issues:

memo() retains SSR output across requests, leading to cross-user data disclosure

Affects: hono/jsx (server-side rendering). Fixes memo() reusing a retained render result across requests when props compare equal, where a component reading request-scoped values from ambient context — useContext(), useRequestContext(), or getContext() — could serve HTML rendered for another user's request, disclosing account data or request-scoped secrets such as CSRF tokens. GHSA-f23p-vx2j-j53r

ReDoS in CORS middleware via Access-Control-Request-Headers

Affects: hono/cors. Fixes a whitespace-tolerant regular expression with quadratic backtracking used to parse the Access-Control-Request-Headers preflight header when allowHeaders is not configured (the default), where a single preflight request carrying a long whitespace run could consume seconds of CPU and stall request processing. GHSA-8j4g-w8fx-2239

Algorithmic complexity DoS in Language Middleware

Affects: hono/language. Fixes quadratic string processing in language-tag normalization, where a crafted language tag with a large number of hyphen-separated subtags — supplied via a query parameter, cookie, or Accept-Language header — could cause excessive CPU consumption and block the event loop. GHSA-54fx-42gc-7vw4

Proxy Helper does not remove response headers listed in the Connection header

Affects: hono/proxy. Fixes proxy() forwarding response headers that the origin's Connection header designates as connection-scoped, where headers intended only for the immediate peer — per RFC 9110 Section 7.6.1 — could be exposed to clients, disclosing connection-scoped or internal metadata. GHSA-79qm-7rj5-m7r9

---

Users who use hono/jsx for server-side rendering, hono/cors, hono/language, or hono/proxy are strongly encouraged to upgrade to this version.
