Bump hono from 4.12.4 to 4.12.12 in /backend/src/mithrandir

[dependabot]

Bumps hono from 4.12.4 to 4.12.12.

Release notes

Sourced from hono's releases.

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

---

Users who use Serve Static, Static Site Generation, Cookie utilities, or IP restriction middleware are strongly encouraged to upgrade to this version.

[claude]

LGTM — straightforward security patch bumping hono to address multiple CVEs.

Extended reasoning...

Overview

This PR updates hono from 4.12.4 to 4.12.12 in backend/src/mithrandir, touching only package.json and package-lock.json. The diff is a mechanical version bump with no logic changes.

Security Risks

The upgrade is a security fix release addressing five vulnerabilities (middleware bypass via repeated slashes, path traversal in toSSG(), IPv4-mapped IPv6 bypass in ipRestriction(), missing cookie name validation on write path, and non-breaking space prefix bypass in getCookie()). Upgrading eliminates these risks; not upgrading would leave them open.

Level of Scrutiny

Low — this is a Dependabot-generated patch-level dependency update. The change is entirely confined to package manifest files with no application logic touched.

Other Factors

No bugs were found by the automated review. No prior reviews exist on this PR. The lock file integrity hash is updated consistently with the new version, and the semver range (^4.12.12) is correct.
