medium Tenable Cloud Security Plugin ID 463449

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.12.25, on
 Windows hosts, an encoded backslash (%5C) in the request path decodes to \, which the Windows path
 resolver treats as a separator. serve-static then resolves a single URL segment such as admin\secret.txt
 into a nested file under the root and serves it, letting an attacker read static files meant to be
 protected behind prefix-mounted middleware. This vulnerability is fixed in 4.12.25. (CVE-2026-54286)

Solution

Update the hono library and its related packages to version 4.12.25 or later.
