chore(deps): bump hono from 4.12.4 to 4.12.18 in /apps/examples/hono-example

[dependabot]

Bumps hono from 4.12.4 to 4.12.18.

Release notes

Sourced from hono's releases.

v4.12.18

Security fixes

This release includes fixes for the following security issues:

Cache Middleware ignores Vary: Authorization / Vary: Cookie leading to cross-user cache leakage

Affects: Cache Middleware. Fixes missing cache-skip handling for Vary: Authorization and Vary: Cookie, where a response cached for one authenticated user could be served to other users. GHSA-p77w-8qqv-26rm

CSS Declaration Injection via Style Object Values in JSX SSR

Affects: hono/jsx. Fixes a missing CSS-context escape for style object values and property names, where untrusted input could inject additional CSS declarations. The impact is limited to CSS and does not allow JavaScript execution. GHSA-qp7p-654g-cw7p

Improper validation of NumericDate claims (exp, nbf, iat) in JWT verify()

Affects: hono/utils/jwt. Fixes improper validation of exp, nbf, and iat claims, where falsy, non-finite, or non-numeric values could silently bypass time-based checks instead of being rejected per RFC 7519. GHSA-hm8q-7f3q-5f36

---

Users who use the JWT helper, hono/jsx, or the Cache middleware are strongly encouraged to upgrade to this version.

v4.12.17

Full Changelog: honojs/hono@v4.12.16...v4.12.17

v4.12.16

Security fixes

This release includes fixes for the following security issues:

Unvalidated JSX Tag Names in hono/jsx May Allow HTML Injection

Affects: hono/jsx. Fixes missing validation of JSX tag names when using jsx() or createElement(), which could allow HTML injection if untrusted input is used as the tag name. GHSA-69xw-7hcm-h432

bodyLimit() can be bypassed for chunked / unknown-length requests

Affects: Body Limit Middleware. Fixes late enforcement for request bodies without a reliable Content-Length (e.g. chunked requests), where oversized requests could reach handlers and return successful responses before being rejected. GHSA-9vqf-7f2p-gf9v

v4.12.15

What's Changed

• fix(jwt): support single-line PEM keys by @​hiendv in honojs/hono#4889

Greptile Summary

This PR bumps hono from 4.12.4 to 4.12.18 in the Hono example app, pulling in a series of bug fixes and several security patches across the intermediate releases.

• v4.12.16 fixes HTML injection via unvalidated JSX tag names and a bodyLimit() bypass for chunked requests.
• v4.12.18 fixes cross-user cache leakage when Vary: Authorization/Vary: Cookie headers are present, CSS declaration injection via style object values in JSX SSR, and improper JWT NumericDate claim validation (exp, nbf, iat) that could silently bypass time-based checks.

Confidence Score: 5/5

Safe to merge — a straightforward patch-range version bump that resolves multiple known security vulnerabilities with no API-breaking changes.

The change is a single-line version bump in an example app's package.json. All fixes in the 4.12.4 → 4.12.18 range are backward-compatible patches, and the security issues addressed (JWT bypass, cache leakage, JSX injection, bodyLimit bypass) are genuine improvements with no risk of regression for existing usage.

No files require special attention.
