The cookie npm package, designed for parsing and serializing HTTP cookies, saw a notable update between version 0.0.6 and version 0.1.0. Both versions, authored by Roman Shtylman, share the same core functionality of enabling Node.js applications to easily handle cookies. They also maintain consistent development dependencies, relying on Mocha for testing. Examining the package.json files reveals minimal structural changes beyond the version number itself. Both versions lack specific runtime dependencies or optional dependencies, suggesting a self-contained library focused purely on cookie manipulation. The git repository remains constant, indicating continued development and maintenance under the same project.
The primary distinction lies in the advancement from version 0.0.6 to 0.1.0 potentially marking an increment in stability, performance enhancements, or subtle bug fixes. While the absence of explicit changelogs makes pinpointing the exact modifications challenging, the increment signifies a step forward in the library's evolution. For developers, the update implies accessing the most current and potentially improved iteration of the package. Given the utility's core function, migrating to the newer version could introduce refinements to cookie handling, potentially resulting in a more robust and reliable experience. Developers should consider the release date difference between the versions for insights into the recency of improvements.
All the vulnerabilities related to the version 0.1.0 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.
