SCA: security update for koa (GHSA-g8mr-fgfg-5qpc)

medium Tenable Cloud Security Plugin ID 435695

Description

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

 - Koa is expressive middleware for Node.js using ES2017 async functions. In versions 2.16.2 to before 2.16.3
 and 3.0.1 to before 3.0.3, a bypass to CVE-2025-8129 was discovered in the Koa.js framework affecting its
 back redirect functionality. In certain circumstances, an attacker can manipulate the Referer header to
 force a user’s browser to navigate to an external, potentially malicious website. This occurs because the
 implementation incorrectly treats some specially crafted URLs as safe relative paths. Exploiting this
 vulnerability could allow attackers to perform phishing, social engineering, or other redirect-based
 attacks on users of affected applications. This issue has been patched in version 3.0.3. (CVE-2025-62595)
