Cookie, a popular npm package for parsing and serializing HTTP cookies, saw a minor version bump from 0.1.4 to 0.1.5 in September 2015. Both versions share the same core functionality, providing developers with tools to easily manage cookies within their JavaScript applications. The package offers simple methods for reading cookie values from request headers and constructing cookie strings for setting cookies in responses. Key benefits include its lightweight nature, straightforward API, and compatibility across various JavaScript environments.
While the fundamental features remain consistent, the update from 0.1.4 to 0.1.5 likely incorporates minor bug fixes or performance improvements. Developers relying on older versions are encouraged to upgrade to ensure they benefit from the latest enhancements and stability patches. Both versions leverage the same testing and coverage tools, Mocha and Istanbul, indicating a continued commitment to quality and reliability. The MIT license provides developers with the freedom to use, modify, and distribute the package without restrictions. Given the close release dates, the changes between versions are probably subtle, but keeping up with the newest version is advisable for optimal performance. The package, authored by Roman Shtylman, remains a dependable choice for handling cookie-related tasks in web development projects.
All the vulnerabilities related to the version 0.1.5 of the package
cookie accepts cookie name, path, and domain with out of bounds characters
The cookie name could be used to set other fields of the cookie, resulting in an unexpected cookie value. For example, serialize("userName=<script>alert('XSS3')</script>; Max-Age=2592000; a", value) would result in "userName=<script>alert('XSS3')</script>; Max-Age=2592000; a=test", setting userName cookie to <script> and ignoring 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.
Avoid passing untrusted or arbitrary values for these fields, ensure they are set by the application instead of user input.
