Summary of Changes

Hello @codingdud, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request automates the upgrade of the express framework to its latest stable version, 4.22.1. The primary motivation for this update is to enhance the application's security posture by resolving known vulnerabilities, including XSS and ReDoS, and to ensure the project benefits from the latest stability improvements and dependency updates within the express ecosystem. This update also includes the reversion of a breaking change from the previous express version, contributing to overall system robustness.

Highlights

  • Dependency Upgrade: The express dependency has been upgraded from version 4.21.0 to 4.22.1 to ensure the application benefits from the latest features and security patches.
  • Security Vulnerability Fixes: This upgrade addresses two medium-severity security vulnerabilities: Cross-site Scripting (XSS) (SNYK-JS-COOKIE-8163060) and Regular Expression Denial of Service (ReDoS) (SNYK-JS-PATHTOREGEXP-8482416).
  • Erroneous Breaking Change Reversion: Version 4.22.1 of express specifically reverts an erroneous breaking change related to the extended query parser that was introduced in the 4.22.0 release, ensuring stability.
  • Transitive Dependency Updates: Several transitive dependencies, including cookie, path-to-regexp, and qs (nested under express), have been updated as part of this express upgrade, reflecting a broader refresh of the dependency tree.

Code Review

This pull request, automatically generated by Snyk, upgrades the express dependency from version 4.21.0 to 4.22.1. This is a necessary security update to resolve two medium-severity vulnerabilities: a Cross-Site Scripting (XSS) issue and a Regular Expression Denial of Service (ReDoS) issue. The changes are confined to package.json and package-lock.json and correctly reflect the version bump. As this is a minor version update, no breaking changes are expected. The changes look good and I recommend merging this PR to enhance the application's security.
