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

Snyk changed the following file(s):

  • plugins/catalog-backend-module-bitbucket/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.

Walkthrough

This PR updates dependency management in the Bitbucket catalog backend module by transitioning from workspace protocol references to explicit version pinning for Backstage packages. Four core Backstage dependencies are locked to specific versions to ensure consistent builds and compatibility. Additionally, the lodash library is upgraded from version 4.17.21 to 4.17.23, which likely addresses known security vulnerabilities or includes important bug fixes. These changes improve dependency stability and security posture of the module.

Changes

File(s) Summary
plugins/catalog-backend-module-bitbucket/package.json Updated dependency specifications: pinned @backstage/backend-common to 0.24.1, @backstage/integration to 0.1.0, @backstage/plugin-bitbucket-cloud-common to 0.1.0, and @backstage/plugin-catalog-node to 1.13.0, replacing workspace protocol references; upgraded lodash from ^4.17.21 to ^4.17.23.

Code Review

This pull request, automatically generated by Snyk, aims to fix several security vulnerabilities by updating dependencies. However, the proposed changes are not suitable for this monorepo environment and are likely to break the build.

The main issue is that Snyk has replaced workspace:^ dependencies with fixed versions, which breaks the yarn workspace linking. Furthermore, some of these fixed versions are significant downgrades from what's currently in the workspace (e.g., @backstage/integration is downgraded from 1.5.1 to 0.1.0). Additionally, the yarn.lock file has not been updated, meaning the changes would not be applied even if merged.

Given these critical issues, I recommend rejecting these changes. The vulnerabilities should be addressed by updating the dependencies correctly within the monorepo structure and ensuring the yarn.lock file is updated accordingly. It's also worth noting that this package (@backstage/plugin-catalog-backend-module-bitbucket) is deprecated, and migrating away from it might be a better long-term solution.

This automated dependency update is incorrect for a yarn workspace monorepo and should be reverted.

  • Broken Workspace Links: Changing workspace:^ to pinned versions breaks the monorepo structure. It forces this package to use published versions from the npm registry instead of local workspace versions, which can lead to major inconsistencies.
  • Dependency Downgrades: Some pinned versions are severe downgrades (e.g., @backstage/integration from workspace version 1.5.1 to 0.1.0), which will likely break the build.
  • Missing Lockfile Update: The yarn.lock file hasn't been updated, so these changes would have no effect.

The correct approach is to update dependencies across the workspace and regenerate yarn.lock by running yarn install. I've suggested reverting these changes.
