Vulnerability Details

cookie is a basic HTTP cookie parser and serializer for HTTP servers. The cookie name could be used to set other fields of the cookie, resulting in an unexpected cookie value. A similar escape can be used for path and domain, which could be abused to alter other fields of the cookie. Upgrade to 0.7.0, which updates the validation for name, path, and domain.

CVE-2025-7339

Vulnerable Library - on-headers-1.0.2.tgz

Execute a listener when a response is about to write headers

Library home page: https://registry.npmjs.org/on-headers/-/on-headers-1.0.2.tgz

Path to dependency file: /package.json

Path to vulnerable library: /node_modules/on-headers/package.json

Dependency Hierarchy:

• express-session-1.17.3.tgz (Root Library)
  • ❌ on-headers-1.0.2.tgz (Vulnerable Library)

Found in base branch: main

Vulnerability Details

on-headers is a node.js middleware for listening to when a response writes headers. A bug in on-headers versions "<1.1.0" may result in response headers being inadvertently modified when an array is passed to "response.writeHead()". Users should upgrade to version 1.1.0 to receive a patch. Uses are strongly encouraged to upgrade to "1.1.0", but this issue can be worked around by passing an object to "response.writeHead()" rather than an array.
