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

Snyk changed the following file(s):

  • plugins/search-backend-module-pg/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 search-backend-module-pg plugin by transitioning from workspace protocol references to explicit version numbers for Backstage packages. The changes pin specific versions for backend-common (0.24.1), backend-plugin-api (1.6.1), plugin-search-backend-node (0.1.2), and plugin-search-common (0.3.1). Additionally, the lodash dependency is upgraded from ^4.17.21 to ^4.17.23, which likely addresses known security vulnerabilities. These modifications indicate preparation for independent package publishing or establishing stricter version control across the dependency tree.

Changes

File(s) Summary
plugins/search-backend-module-pg/package.json Replaced workspace protocol references with explicit version numbers for @backstage/backend-common (0.24.1), @backstage/backend-plugin-api (1.6.1), @backstage/plugin-search-backend-node (0.1.2), and @backstage/plugin-search-common (0.3.1); upgraded lodash from ^4.17.21 to ^4.17.23.

Code Review

This pull request, automatically generated by Snyk, aims to resolve several security vulnerabilities by updating dependencies. While the intention to improve security is appreciated, there are critical issues with the proposed changes that need to be addressed before this PR can be merged.

Most importantly, the PR description explicitly warns: Failed to update the yarn.lock, please update manually before merging. Merging this PR without an updated yarn.lock file will lead to inconsistent dependency installations and likely break the project. The yarn.lock file must be generated and included in this pull request.

Additionally, several @backstage dependencies have been changed from using the workspace:^ protocol to being pinned to specific versions from the npm registry. This is a fundamental change to how this Backstage monorepo is structured and will almost certainly break local development workflows and continuous integration builds. The correct way to handle these updates is by managing the versions of the packages within the workspace, not by pinning them to external versions.

While the update to lodash appears correct, the other changes need to be reverted and addressed in a way that respects the monorepo architecture.

critical

These changes replace workspace:^ with pinned versions for several @backstage packages. This is a significant and likely incorrect change for a Backstage monorepo. The workspace: protocol is used by Yarn to link to local packages within this monorepo. Pinning to external registry versions will break this linkage, potentially causing build failures, incorrect behavior during local development, and issues with dependency resolution.

The correct approach to update these dependencies and resolve their transitive vulnerabilities is to update the source packages within the monorepo itself and then run yarn install to update the yarn.lock file.

I recommend reverting these specific changes and addressing the vulnerabilities by updating the appropriate packages within the workspace. The lodash update on line 45 is likely correct, but these changes for @backstage packages are problematic.

    "@backstage/backend-plugin-api": "workspace:^",
    "@backstage/config": "workspace:^",
    "@backstage/plugin-search-backend-node": "workspace:^",
