Snyk has created this PR to fix 1 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

  • packages/@vuepress/markdown/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.

Code Review

This pull request correctly updates the markdown-it dependency in package.json to version 14.1.1, which patches a security vulnerability. However, the change is incomplete as the yarn.lock file was not updated. This is a critical omission that prevents the fix from being applied. Before merging, you must manually run yarn install to update the lock file and commit the resulting changes.

"dependencies": {
"@vuepress/shared-utils": "1.9.10",
"markdown-it": "^14.1.0",
"markdown-it": "^14.1.1",

security-critical critical

While this dependency update is correct, it's incomplete because the yarn.lock file has not been updated. This means the security fix will not actually be applied to your project's builds. Please run yarn install and commit the updated yarn.lock file to complete this upgrade.
