Vulnerable Library - koa-2.6.2.tgz

Path to dependency file: /package.json

Path to vulnerable library: /node_modules/koa/package.json

Dependency Hierarchy:

• ❌ koa-2.6.2.tgz (Vulnerable Library)

Found in base branch: main

Vulnerability Details

Koa is expressive middleware for Node.js using ES2017 async functions. Prior to versions 0.21.2, 1.7.1, 2.15.4, and 3.0.0-alpha.3, Koa uses an evil regex to parse the "X-Forwarded-Proto" and "X-Forwarded-Host" HTTP headers. This can be exploited to carry out a Denial-of-Service attack. Versions 0.21.2, 1.7.1, 2.15.4, and 3.0.0-alpha.3 fix the issue.
