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

Snyk changed the following file(s):

  • packages/backend-app-api/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 pull request updates the dependency management strategy in the backend-app-api package by replacing workspace protocol references with explicit version numbers for seven Backstage packages. The affected packages include backend-common (0.24.1), backend-plugin-api (1.6.1), backend-tasks (0.6.1), config-loader (0.6.10), plugin-auth-node (0.1.0), and plugin-permission-node (0.1.0). Additionally, the lodash dependency is upgraded from version 4.17.21 to 4.17.23, which likely addresses known security vulnerabilities. This transition from workspace dependencies to pinned versions typically indicates preparation for package publishing or production deployment, ensuring consistent and reproducible builds across different environments.

Code Review

This pull request, automatically generated by Snyk, aims to fix several vulnerabilities by updating dependencies. However, the proposed changes to package.json are problematic for this monorepo. The PR replaces workspace:^ specifiers with pinned versions, including several significant downgrades, which will likely break the build and defeats the purpose of using yarn workspaces. These changes should be rejected.

Additionally, as noted in the PR description, the yarn.lock file has not been updated. This is a critical omission. Any dependency changes must be accompanied by an updated lock file to ensure consistent and correct dependency resolution.

The recommended course of action is to close this PR and address the vulnerabilities by updating the dependencies correctly within the yarn workspace structure, ensuring yarn.lock is updated and committed.

critical

This automated change from Snyk seems to be mishandling the yarn workspace setup. It's replacing workspace:^ dependencies with pinned versions. This breaks the monorepo's dependency management strategy and can lead to several issues:

  • Inconsistent versions: Packages within the monorepo will no longer use the version from the workspace, leading to inconsistencies and potential bugs.
  • Incorrect downgrades: Some of the pinned versions are significant downgrades from the versions currently in the workspace, which will likely cause compilation or runtime errors. For example:
    • @backstage/config-loader is being downgraded from 1.4.0-next.0 to 0.6.10.
    • @backstage/plugin-auth-node is being downgraded from 0.2.17-next.0 to 0.1.0.
    • @backstage/plugin-permission-node is being downgraded from 0.7.11-next.0 to 0.1.0.
  • Maintenance overhead: Manually managing these versions will be difficult in the long run.

The correct way to fix these vulnerabilities is likely to update the affected packages across the entire workspace or update the root dependencies and then run yarn to propagate the changes.

I recommend reverting these changes to the workspace dependencies. The lodash upgrade on line 54 seems correct, but it should be applied along with an update to yarn.lock.
