[dependabot]

Bumps the npm_and_yarn group with 1 update in the /apps/backend directory: hono.

Updates hono from 4.12.8 to 4.12.21

Release notes

Sourced from hono's releases.

v4.12.21

Security fixes

This release includes fixes for the following security issues:

app.mount() strips mount prefix using undecoded path, causing incorrect routing for percent-encoded paths

Affects: app.mount(). Fixes prefix stripping using the raw URL pathname instead of the decoded path, where percent-encoded characters in the mount prefix or path could cause the prefix to be removed at the wrong position, resulting in the sub-application receiving an incorrect path. GHSA-2gcr-mfcq-wcc3

IP Restriction bypasses static deny rules for non-canonical IPv6

Affects: hono/ip-restriction. Fixes IP address comparison using string equality, where non-canonical IPv6 representations of a denied address — such as compressed forms or hex-notation IPv4-mapped addresses — could bypass static deny rules. GHSA-xrhx-7g5j-rcj5

Cookie helper does not sanitize sameSite and priority, allowing Set-Cookie injection

Affects: hono/cookie. Fixes missing validation of sameSite and priority options against injection characters (;, \r, \n), where user-controlled input passed to either option could inject additional attributes into the Set-Cookie response header. GHSA-3hrh-pfw6-9m5x

JWT middleware accepts any Authorization scheme, not only Bearer

Affects: hono/jwt, hono/jwk. Fixes missing scheme validation in the Authorization header, where any two-part header value was accepted regardless of the scheme name, allowing non-Bearer schemes to pass JWT authentication. GHSA-f577-qrjj-4474

---

Users who use app.mount(), hono/ip-restriction, hono/cookie, or hono/jwt/hono/jwk are encouraged to upgrade to this version.

Greptile Summary

Routine Dependabot bump of hono from 4.12.8 to 4.12.21 in apps/backend. The upgrade is a patch-range update that picks up four security advisories fixed in v4.12.21, along with several bug fixes in the intermediate releases.

• Security fixes (v4.12.21): Incorrect percent-encoded path stripping in app.mount() (GHSA-2gcr-mfcq-wcc3), non-canonical IPv6 bypass in hono/ip-restriction (GHSA-xrhx-7g5j-rcj5), Set-Cookie header injection via sameSite/priority in hono/cookie (GHSA-3hrh-pfw6-9m5x), and any-scheme acceptance in hono/jwt/hono/jwk (GHSA-f577-qrjj-4474).
• Bug fixes: Duplicate cookie name handling (returns first), base path preservation for mounted route() apps, @hono/node-server v2 upgrade with fixed abort handling, and other minor JSX/serveStatic improvements.

Confidence Score: 5/5

Safe to merge — single-line patch-range version bump that brings in security fixes with no API-breaking changes.

The change is a single version bump of hono across a patch range (4.12.8 → 4.12.21). All intermediate releases are bug fixes or security patches with no breaking changes documented. The upgrade is advisable given the four security advisories it resolves.

No files require special attention.
