Snyk has created this PR to fix 2 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

  • plugins/events-backend-module-aws-sqs/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 for the AWS SQS events backend module by replacing workspace protocol references with fixed version numbers. Three Backstage dependencies are pinned to specific versions: backend-plugin-api (0.1.0), backend-tasks (0.6.1), and plugin-events-node (0.1.0). This change transitions from using the monorepo workspace protocol (workspace:^) to explicit version constraints, which is typically done when preparing a package for independent publication or when establishing stricter version control requirements for external distribution.

Code Review

This pull request from Snyk aims to resolve two security vulnerabilities by pinning several @backstage dependencies to specific versions. While the intent is good, the execution is flawed for a monorepo using Yarn workspaces. The changes replace the workspace:^ protocol with hardcoded versions, which is an anti-pattern in this context. This breaks the internal linking of the monorepo, can cause dependency conflicts, and in this case, introduces severe downgrades for two packages, which is likely to cause breaking changes. Furthermore, the PR description explicitly states that the yarn.lock file could not be updated, which confirms that the proposed dependency changes are invalid. I have left a critical review comment suggesting to revert these changes and address the vulnerabilities through proper workspace dependency management.

critical

This automated change incorrectly pins dependencies to fixed versions, replacing the workspace:^ protocol. This is problematic in a Yarn workspace monorepo for several reasons:

  • Breaks Workspace Linking: It severs the link to the local workspace packages, which can cause multiple versions of the same dependency to be included in the project, leading to bugs and increased bundle size.
  • Major Version Downgrades: The change downgrades @backstage/backend-plugin-api from a 0.5.x version to 0.1.0, and @backstage/plugin-events-node from 0.2.x to 0.1.0. Such significant downgrades are almost guaranteed to introduce breaking API changes and are not a safe way to patch vulnerabilities.
  • Incomplete Fix: The PR description notes that yarn.lock failed to update. This is a critical failure, indicating that the dependency resolution is broken. Merging this would leave the repository in an inconsistent state.

To properly fix the vulnerabilities, the root cause should be investigated and the appropriate dependencies should be updated across the workspace, followed by running yarn to correctly update the lockfile. This automated change should be reverted.
