Snyk has created this PR to fix 3 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

  • scripts/package.json
  • scripts/yarn.lock

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.

Vulnerabilities that will be fixed with an upgrade:

Issue Score
high severity Regular Expression Denial of Service (ReDoS)

Code Review

This Snyk PR updates dependencies to fix three vulnerabilities. While the minor bumps for express and prettier-plugin-merge are fine, the major upgrade of eslint from v8 to v10 is highly risky. It's likely to break your linting setup due to significant breaking changes in ESLint. I've added a critical comment suggesting a safer alternative: using a yarn resolution to patch the vulnerable ajv package directly, without the disruptive eslint upgrade.

"esbuild": "^0.23.0",
"esbuild-plugin-alias": "^0.2.1",
"eslint": "^8.57.0",
"eslint": "^10.0.0",

critical

This upgrade of eslint from v8 to v10 is a major version bump that will likely break your linting setup. ESLint v9 introduced a new configuration system (flat config), and many plugins require updates for compatibility with v9/v10. Your project's .eslintrc.cjs is using the legacy format.

The vulnerability this change aims to fix is in ajv, a transitive dependency. A safer alternative is to force a specific version of ajv using a resolutions field in package.json. This avoids the breaking changes from a major eslint upgrade.

I recommend reverting this change and adding the following to your resolutions in package.json:

"resolutions": {
  ...
  "ajv": ">=6.12.6"
}

Then run yarn install to apply the resolution.

Suggested change
"eslint": "^10.0.0",
"eslint": "^8.57.0",
