chore(deps): bump hono from 4.12.4 to 4.12.18

[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.

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 across both the example app and the hono package, along with the corresponding pnpm-lock.yaml updates. The upgrade addresses multiple security advisories disclosed between the two versions.

• Security fixes included: JWT NumericDate bypass (GHSA-hm8q-7f3q-5f36), Cache Middleware cross-user cache leakage via Vary: Authorization/Cookie (GHSA-p77w-8qqv-26rm), CSS injection in JSX SSR style objects (GHSA-qp7p-654g-cw7p), HTML injection via unvalidated JSX tag names (GHSA-69xw-7hcm-h432), and bodyLimit() bypass for chunked requests (GHSA-9vqf-7f2p-gf9v).
• Collateral lock file updates include turbo (2.9.3 → 2.9.12), graphql (16.12.0 → 16.14.0), tough-cookie (6.0.0 → 6.0.1), type-fest (5.3.1 → 5.6.0), and tldts (7.0.19 → 7.0.30) — all resolved transitively by pnpm and consistent with the dependency graph.

Confidence Score: 5/5

Safe to merge — this is a security-motivated patch-range bump with no API-breaking changes and well-validated collateral lock updates.

All three changed files are version number updates: two package.json pins and the regenerated lock file. The hono upgrade stays within a stable minor (4.12.x), every collateral transitive update is a patch or minor bump, and the deprecated packages surfaced in the lock file (uuid, glob, @ungap/structured-clone) pre-exist this PR and are not introduced by it.

No files require special attention; the lock file collateral changes are mechanical pnpm re-resolves consistent with the declared semver ranges.

Important Files Changed

Filename	Overview
apps/examples/hono-example/package.json	Pins hono from 4.12.4 to 4.12.18; straightforward version bump with no other changes.
packages/hono/package.json	Pins hono devDependency from 4.12.4 to 4.12.18; consistent with the example app change.
pnpm-lock.yaml	Lock file regenerated to reflect hono 4.12.18 and transitively updated packages (turbo, graphql, tough-cookie, type-fest, tldts). New deprecation notices for @ungap/structured-clone, glob, and uuid are surfaced but pre-exist this change.
