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

Snyk changed the following file(s):

  • code/frameworks/server-webpack5/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 @q1blue, 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, focuses on enhancing the project's security by upgrading a key dependency. The primary objective is to resolve a known vulnerability by updating @storybook/builder-webpack5 to its 7.1.0 version. This change is crucial for mitigating a medium-severity security risk.

Highlights

  • Dependency Upgrade: The @storybook/builder-webpack5 dependency has been upgraded from workspace:* to version 7.1.0.
  • Security Fix: This upgrade addresses a medium-severity vulnerability (SNYK-JS-TAR-15038581) related to 'Improper Handling of Unicode Encoding' found in the tar package, which is a transitive dependency.
  • Yarn Zero-Install Note: Users utilizing Yarn's zero-install feature will need to manually run yarn to update the .yarn/cache/ directory, as this PR does not automatically update it.
  • Manual yarn.lock Update Required: The yarn.lock file failed to update automatically and requires manual intervention before merging this pull request.

Code Review

This pull request, automatically generated by Snyk, aims to fix a security vulnerability by changing the version of @storybook/builder-webpack5. However, the proposed change is incorrect and will likely break the project. It replaces a workspace:* dependency with a hardcoded, older major version (7.1.0), while the rest of the monorepo uses version 8.3.0-beta.3. This version mismatch will cause issues. The change should be reverted, and the vulnerability should be addressed by other means, such as using yarn resolutions to update the vulnerable transitive dependency (tar).

critical

This automated change incorrectly replaces a workspace:* dependency with a hardcoded older version (7.1.0). The local version of @storybook/builder-webpack5 in this monorepo is 8.3.0-beta.3. Downgrading to 7.1.0 will cause version mismatches with other @storybook/* packages that are on workspace:* (i.e., 8.3.0-beta.3) and will likely break the build.

While this change is intended to fix a security vulnerability, it's likely to introduce breaking changes. The correct approach would be to address the underlying vulnerability (in the tar package) via yarn resolutions or by updating the transitive dependency chain, rather than downgrading a major component of Storybook.
