v4.12.14

Security fixes

This release includes fixes for the following security issues:

Improper handling of JSX attribute names in hono/jsx SSR

Other changes

• fix(aws-lambda): handle invalid header names in request processing (#4883) fa2c74fe

v4.12.13

v4.12.12

Security fixes

This release includes fixes for the following security issues:

Middleware bypass via repeated slashes in serveStatic

Affects: Serve Static middleware. Fixes a path normalization inconsistency where repeated slashes (//) could bypass route-based middleware protections and allow access to protected static files. GHSA-wmmm-f939-6g9c

Path traversal in toSSG() allows writing files outside the output directory

Affects: toSSG() for Static Site Generation. Fixes a path traversal issue where crafted ssgParams values could write files outside the configured output directory. GHSA-xf4j-xp2r-rqqx

Incorrect IP matching in ipRestriction() for IPv4-mapped IPv6 addresses

Affects: IP Restriction Middleware. Fixes improper handling of IPv4-mapped IPv6 addresses (e.g. ::ffff:127.0.0.1) that could cause allow/deny rules to be bypassed. GHSA-xpcf-pg52-r92g

Missing validation of cookie name on write path in setCookie()

Affects: setCookie(), serialize(), and serializeSigned() from hono/cookie. Fixes missing validation of cookie names on the write path, preventing inconsistent handling between parsing and serialization. GHSA-26pp-8wgv-hjvm

Non-breaking space prefix bypass in cookie name handling in getCookie()

Affects: getCookie() from hono/cookie. Fixes a discrepancy in cookie name handling that could allow attacker-controlled cookies to override legitimate ones and bypass prefix protections. GHSA-r5rp-j6wh-rvv4

[claude]

LGTM — straightforward Dependabot security update bumping hono from 4.12.4 to 4.12.14.

Extended reasoning...

Overview

This PR updates the hono dependency in backend/src/mithrandir from 4.12.4 to 4.12.14. Changes are confined to package.json (version constraint) and package-lock.json (resolved version + integrity hash). No application logic is modified.

Security risks

The update addresses multiple upstream CVEs (cookie name bypass, middleware bypass via repeated slashes, path traversal in toSSG, IP restriction bypass for IPv4-mapped IPv6 addresses, JSX attribute injection). There is no new security risk introduced; this is a net security improvement.

Level of scrutiny

Low. This is a mechanical Dependabot-generated lockfile update with no code changes. The new integrity hash in the lockfile matches the published package, and no other dependencies are affected.

Other factors

No bugs were found by the automated bug hunting system. No prior reviews exist on this PR. The change is fully contained within the mithrandir backend package and does not affect shared infrastructure or application logic.
