chore(deps): bump hono from 4.12.9 to 4.12.27

[dependabot]

Bumps hono from 4.12.9 to 4.12.27.

Release notes

Sourced from hono's releases.

v4.12.27

Security fixes

This release includes fixes for the following security issues:

hono/jsx does not isolate context per request

Affects: hono/jsx, hono/jsx-renderer. During SSR, context was stored process-wide instead of per request, so useContext()/useRequestContext() read after an await in an async component could return another concurrent request's value — leading to cross-request data disclosure or authorization checks against the wrong request. GHSA-hvrm-45r6-mjfj

Server-Side XSS via JSX escaping bypass in cx()

Affects: hono/css. cx() marked its composed class name as already-escaped without escaping the input, so untrusted input passed as a class name could break out of the JSX class attribute during SSR and inject markup (XSS). GHSA-w62v-xxxg-mg59

API Gateway v1 adapter can drop a repeated request header value

Affects: hono/aws-lambda. The API Gateway v1 (and VPC Lattice) adapter de-duplicated repeated header values by substring instead of exact match, dropping a value that is a substring of another (e.g. 203.0.113.1 dropped when 203.0.113.10 is present) — affecting logic such as X-Forwarded-For-based IP restriction. GHSA-xgm2-5f3f-mvvc

---

Users of hono/jsx/hono/jsx-renderer, hono/css (cx()), or the hono/aws-lambda API Gateway v1 / VPC Lattice adapters are encouraged to upgrade.

v4.12.26

Full Changelog: honojs/hono@v4.12.25...v4.12.26

v4.12.25

Security fixes

This release includes fixes for the following security issues:

CORS Middleware reflects any Origin with credentials when origin defaults to the wildcard

Affects: hono/cors. Fixes the wildcard origin reflecting the request Origin and sending Access-Control-Allow-Credentials: true when credentials: true is set without an explicit origin, where any site a logged-in user visited could make credentialed cross-origin requests and read responses from cookie-authenticated endpoints. GHSA-88fw-hqm2-52qc

Body Limit Middleware can be bypassed on AWS Lambda by understating Content-Length

Affects: hono/body-limit on AWS Lambda (hono/aws-lambda, hono/lambda-edge). Fixes the request being built with the client-declared Content-Length while the body is delivered fully buffered, where a client could declare a small Content-Length with a much larger body and slip past the configured size limit. GHSA-rv63-4mwf-qqc2

Path traversal in serve-static on Windows via encoded backslash (%5C)

Affects: serveStatic on Windows (Node, Bun, Deno adapters). Fixes the path guard allowing a lone backslash, where an encoded backslash (%5C) decoded to \ was treated as a separator by the Windows path resolver, letting a single URL segment escape into a middleware-guarded subtree. GHSA-wwfh-h76j-fc44

AWS Lambda adapter merges multiple Set-Cookie headers into one value, dropping cookies on ALB single-header and Lattice
