[Snyk] Fix for 1 vulnerabilities

[hashim21223445]

Snyk has created this PR to fix 1 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

• packages/@vuepress/core/package.json

Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

⚠️ Warning

Failed to update the yarn.lock, please update manually before merging.

Summary of Changes

Hello @hashim21223445, 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, automatically generated by Snyk, aims to enhance the project's security posture by resolving a critical 'Prototype Pollution' vulnerability. It achieves this by upgrading two key dependencies, js-yaml and optimize-css-assets-webpack-plugin, to their patched versions. The primary goal is to ensure the application remains robust against known security exploits, though a manual step is noted for yarn.lock synchronization.

Highlights

• Vulnerability Fix: This pull request addresses and fixes one identified vulnerability, specifically a 'Prototype Pollution' issue (SNYK-JS-JSYAML-13961110), by updating affected dependencies.
• Dependency Updates: The js-yaml dependency has been updated from version ^3.13.1 to ^3.14.2, and optimize-css-assets-webpack-plugin has been updated from ^5.0.1 to ^6.0.0.
• Manual yarn.lock Update Required: A warning indicates that the yarn.lock file was not automatically updated by Snyk and requires manual intervention before merging, especially for projects using Yarn's zero-installs feature.

Code Review

This pull request, automatically generated by Snyk, addresses a Prototype Pollution vulnerability in js-yaml by upgrading it. It also upgrades optimize-css-assets-webpack-plugin to a new major version. However, this major version upgrade of optimize-css-assets-webpack-plugin introduces a critical compatibility issue with the project's supported Node.js versions. As detailed in the review comment, the new version requires Node.js 10.13.0+, which conflicts with the node >= 8.6 requirement in package.json. This must be addressed before merging. Additionally, as noted in the pull request description, the yarn.lock file has not been updated and must be regenerated manually before merging.

[gemini-code-assist]

This upgrade to optimize-css-assets-webpack-plugin v6.0.0 introduces a breaking change regarding the required Node.js version. This version of the plugin depends on cssnano@5, which requires Node.js >= 10.13.0. However, this project's package.json specifies "engines": { "node": ">=8.6" } on line 75. This will cause build failures for users on Node.js versions between 8.6 and 10.13.0.

To resolve this, you could:

1. Update the project's required Node.js version in the engines field to >=10.13.0 if you are dropping support for older Node versions.
2. Avoid this major upgrade if you need to maintain compatibility with Node.js 8.6+. The vulnerability fix is in js-yaml, so the upgrade of optimize-css-assets-webpack-plugin might not be strictly necessary.
