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

Snyk changed the following file(s):

  • plugins/linguist-backend/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 the dependency management strategy for the linguist-backend plugin by converting five core Backstage dependencies from workspace protocol references to explicit version numbers. The affected packages include backend-common (0.25.0), backend-plugin-api (1.6.1), catalog-client (0.2.0), config (0.1.1), and plugin-auth-node (0.6.0). This selective pinning approach targets essential backend dependencies while maintaining workspace protocol for others, likely in preparation for independent package publication or to ensure consistent versioning across different deployment environments.

Changes

File(s) Summary
plugins/linguist-backend/package.json Converted five Backstage dependencies from workspace protocol to explicit versions: @backstage/backend-common (0.25.0), @backstage/backend-plugin-api (1.6.1), @backstage/catalog-client (0.2.0), @backstage/config (0.1.1), and @backstage/plugin-auth-node (0.6.0).

Code Review

This pull request, automatically generated by Snyk, aims to resolve 6 security vulnerabilities by updating several @backstage dependencies in plugins/linguist-backend/package.json. The dependencies are pinned to specific versions, replacing the workspace:^ protocol. While this addresses the vulnerabilities, it's a significant change that could affect the monorepo's dependency consistency. Most importantly, the PR description warns that the yarn.lock file has not been updated. This is a critical omission that must be addressed by running yarn install and committing the updated lock file to ensure the fixes are applied and to prevent potential build issues.

security-critical critical

This change pins several dependencies to specific versions, moving away from workspace:^. This has two critical implications:

  • Dependency Strategy Change: This alters the monorepo dependency strategy. Using pinned versions instead of workspace packages can lead to version duplication, increased bundle sizes, and potential runtime conflicts. Please confirm this is the intended approach.

  • yarn.lock is Missing: The PR description correctly warns that yarn.lock has not been updated. Without this file, the dependency changes will not take effect, and the security vulnerabilities will not be fixed.

Required Action: Before merging, you must run yarn install to generate the yarn.lock file, commit it to this PR, and then thoroughly test to ensure no regressions have been introduced.
