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

Snyk changed the following file(s):

  • plugins/catalog-backend-module-aws/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, addresses a medium-severity security vulnerability related to improper handling of Unicode encoding. It achieves this by updating and pinning several @backstage dependencies within the plugins/catalog-backend-module-aws/package.json file. Reviewers should note the requirement for a manual yarn.lock update and the implications for Yarn zero-install users.

Highlights

  • Dependency Version Pinning: Several @backstage dependencies in plugins/catalog-backend-module-aws/package.json have been updated from "workspace:^" to specific, pinned versions (e.g., @backstage/backend-common to "0.24.1", @backstage/catalog-model to "0.1.1", etc.).
  • Vulnerability Remediation: This PR aims to fix one medium-severity vulnerability, "Improper Handling of Unicode Encoding" (SNYK-JS-TAR-15038581), by upgrading underlying dependencies.
  • Manual yarn.lock Update Required: Snyk was unable to automatically update the yarn.lock file, requiring a manual update before merging.
  • Zero-Install Cache Invalidation: Users leveraging Yarn's zero-install feature will need to manually run "yarn" to update their .yarn/cache directory after pulling these changes.

Code Review

This pull request, automatically generated by Snyk, aims to fix a vulnerability by updating dependencies in plugins/catalog-backend-module-aws/package.json. However, the proposed changes are problematic for this monorepo. They replace workspace: protocol dependencies with pinned versions, which breaks the intended local package linking. More critically, some of these pinned versions are significant downgrades from the current versions in the workspace, which could introduce bugs or cause breakages. I have provided a comment with a suggestion to revert these changes and outlined the correct approach to fix the vulnerability, which involves updating the transitive dependency (tar) in the appropriate package (@backstage/backend-common) and regenerating the lockfile.

These automated changes from Snyk are incorrect for this monorepo and are likely to cause issues.

  • Breaking Workspace Links: The changes replace workspace:^ dependencies with pinned versions. This breaks the local linking within the monorepo, which is a core part of its structure.
  • Dependency Downgrades: Some of the pinned versions are significant downgrades from the versions currently in the workspace. For example:
    • @backstage/catalog-model is downgraded from 1.4.1 to 0.1.1.
    • @backstage/plugin-catalog-node is downgraded from 1.4.1-next.0 to 1.0.0.
    • @backstage/plugin-kubernetes-common is downgraded from 0.6.5 to 0.1.0.
      These downgrades could re-introduce old bugs or cause compatibility issues.

The vulnerability SNYK-JS-TAR-15038581 is in the tar package, which is a dependency of @backstage/backend-common. The correct fix is to update the tar dependency within packages/backend-common/package.json and then update the yarn.lock file.

These changes should be reverted.
