Snyk changed the following file(s):

  • code/frameworks/preact-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.

Code Review

This pull request aims to address a medium-severity vulnerability by upgrading the @storybook/builder-webpack5 dependency to version 7.1.0 in code/frameworks/preact-webpack5/package.json. While the dependency version has been updated in package.json, it's crucial to ensure the yarn.lock file is also updated to reflect this change and fully apply the security fix. Additionally, the change from workspace:* to a fixed version for an internal package warrants careful consideration to maintain monorepo consistency.

The PR description explicitly states that yarn.lock failed to update. It is critical to manually update the yarn.lock file to ensure that the 7.1.0 version of @storybook/builder-webpack5 is properly locked. Without this, the security fix might not be consistently applied across environments, and dependency resolution could lead to unexpected issues.

The dependency @storybook/builder-webpack5 has been changed from workspace:* to a fixed version 7.1.0. In a Yarn workspace, workspace:* typically signifies that the package should use the local version available within the monorepo. However, the local version of @storybook/builder-webpack5 (as defined in code/builders/builder-webpack5/package.json) is 8.3.0-beta.3. This change means preact-webpack5 will now fetch 7.1.0 from the npm registry, effectively downgrading from the local 8.3.0-beta.3 version and breaking the workspace:* convention. Please confirm if this is the intended behavior, as it could introduce version inconsistencies within the monorepo or unintended external dependencies. If the goal is to use the local, updated version of builder-webpack5, the dependency should ideally remain workspace:*.
