Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Hono is a Web application framework that provides support for any JavaScript runtime. Versions 4.8.0 through 4.9.5 contain a flaw in the getPath utility function which could allow path confusion and potential bypass of proxy-level ACLs (e.g. Nginx location blocks). The original implementation relied on fixed character offsets when parsing request URLs. Under certain malformed absolute-form Request-URIs, this could lead to incorrect path extraction depending on the application and environment. If proxy ACLs are used to protect sensitive endpoints such as /admin, this flaw could have allowed unauthorized access. The confidentiality impact depends on what data is exposed: if sensitive administrative data is exposed, the impact may be high, otherwise it may be moderate. This issue is fixed in version 4.9.6.

Recommended fix High confidence

4.9.6

  1. Check the current version of Hono in your project by running: npm list hono or checking your package.json
  2. Update Hono to version 4.9.6 using your package manager. For npm, run: npm install [email protected]. For yarn, run: yarn add [email protected]. For pnpm, run: pnpm add [email protected]
  3. After upgrading, verify the new version is installed by running npm list hono and confirming it shows version 4.9.6
  4. Review your application's routing and proxy configurations (e.g., Nginx location blocks) to ensure ACLs are functioning as expected with the fixed getPath utility
