How to Fix CVE-2025-58362

To remediate this vulnerability, upgrade all affected Hono dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

hono fixed: 4.9.6 
npm install hono@4.9.6
Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

npm ls hono

How to Check if You Are Affected

To determine whether your Node.js application is affected by CVE-2025-58362, inspect your project dependencies using npm:

npm ls hono

Analyze the terminal output to locate any version of Hono in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than 4.9.6), your application is affected.

Note: The npm ls hono command inspects dependencies declared in your package.json and lockfile; it does not perform automated runtime dynamic scanning.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-706: Use of Incorrectly-Resolved Name or Reference, where the product uses a name or reference to access a resource, but the name/reference resolves to a resource that is outside of the intended control sphere. In Hono, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

### Summary A flaw in the `getPath` utility function could allow path confusion and potential bypass of proxy-level ACLs (e.g. Nginx location blocks). ### Details 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. Most standards-compliant runtimes and reverse proxies reject such malformed requests with a 400 Bad Request, so the impact depends on the application and environment. ### Impact 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 (CVSS 7.5); otherwise it may be Medium (CVSS 5.3). ### Resolution The implementation has been updated to correctly locate the first slash after "://", preventing such path confusion.
