Snyk has created this PR to fix 6 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

  • plugins/fossa/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, automatically generated by Snyk, attempts to fix several vulnerabilities by pinning dependencies in plugins/fossa/package.json. However, the proposed changes are incorrect and will likely break the project. The PR itself warns that it 'Failed to update the yarn.lock', which indicates the dependency resolution failed.

The changes replace workspace: protocol specifiers with very old, hardcoded versions from the public registry. This breaks the monorepo's dependency linking for this package and leads to major downgrades and inconsistencies. I've left a critical comment with a suggestion to revert these changes. The vulnerabilities should be addressed by properly updating dependencies within the workspace, not by applying these automated but incorrect changes.

These changes incorrectly replace workspace:^ dependencies with very old, pinned versions from the public registry. This will break the monorepo structure and likely cause the application to fail to build or run, as it will use outdated versions of internal packages instead of the local versions from the workspace.

For example:

  • @backstage/core-components is being downgraded from a workspace version (which is 0.13.4-next.0 in this monorepo) to 0.1.0.
  • @backstage/plugin-catalog-react is being downgraded to 0.0.1 from a much newer workspace version.
  • @backstage/theme is being downgraded from a workspace version (which is 0.4.1 in this monorepo) to 0.1.1.

These are major downgrades that will introduce breaking changes and regressions. The correct approach to fix the underlying vulnerabilities is to update the dependencies within the monorepo, not to pin them to old public versions. These changes should be reverted.

Walkthrough

This PR updates the dependency management strategy for the fossa plugin by replacing workspace protocol references with fixed version numbers for three Backstage packages. The changes pin @backstage/core-components to version 0.1.0, @backstage/plugin-catalog-react to version 0.0.1, and @backstage/theme to version 0.1.1. This modification moves away from monorepo workspace resolution to explicit version pinning, which typically indicates preparation for standalone package publication or addresses specific version compatibility requirements within the plugin's dependency chain.

Changes

File(s) Summary
plugins/fossa/package.json Updated three Backstage dependencies from workspace protocol to fixed versions: @backstage/core-components to 0.1.0, @backstage/plugin-catalog-react to 0.0.1, and @backstage/theme to 0.1.1.
