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

Snyk changed the following file(s):

  • package.json
  • 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:

medium severity Directory Traversal
SNYK-JS-TAR-15032660

SNYK-JS-LODASH-15053838

Code Review

This pull request from Snyk addresses two security vulnerabilities by updating canvas and lodash. However, the update for lodash to version 4.17.23 is highly suspicious, as this version is not an official release and may pose a security risk. This change should be rejected. The update for canvas is a major version bump to v3.0.0 to resolve a transitive vulnerability. This is a breaking change and requires thorough testing to ensure compatibility with your application, particularly with tools like jest-canvas-mock.

critical

The lodash package is being updated to version 4.17.23. This version is not an official release from the lodash maintainers and is not available on the public npm registry. The yarn.lock file points to a direct .tgz URL from registry.yarnpkg.com, which might be a cached version of a since-unpublished package. This is a significant security risk, as it could be a malicious package (e.g., dependency confusion). It is strongly recommended to reject this change and stick to the latest official version, 4.17.21, until an official patch for SNYK-JS-LODASH-15053838 is released by the lodash team.

high

This is a major version upgrade for canvas (from v2 to v3), which introduces breaking changes as noted by Snyk. While this upgrade is necessary to fix the tar vulnerability (SNYK-JS-TAR-15032660), it requires thorough regression testing of all features that rely on canvas. The project's usage of jest-canvas-mock and other canvas-related tooling should be checked for compatibility with canvas v3.
