  • Check the changes in this PR to ensure they won't cause issues with your project.
  • Max score is 1000. Note that the real score may have changed since the PR was raised.
  • This PR was automatically created by Snyk using the credentials of a real user.
  • Some vulnerabilities couldn't be fully fixed and so Snyk will still find them when the project is tested again. This may be because the vulnerability existed within more than one direct dependency, but not all of the affected dependencies could be upgraded.

Summary of Changes

Hello @nn6n, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request, automatically generated by Snyk, aims to resolve two identified security vulnerabilities by upgrading the urllib3 dependency to a secure version and explicitly pinning it in the test requirements file.

Highlights

  • Security Upgrade: This PR upgrades the urllib3 package from version 1.26.20 to 2.5.0 to address two identified security vulnerabilities (SNYK-PYTHON-URLLIB3-10390193 and SNYK-PYTHON-URLLIB3-10390194).
  • Dependency Management: The urllib3 dependency is now explicitly pinned in test_requirements/requirements_311_core.txt. Previously, it was an indirect dependency of requests, but Snyk has added it directly to ensure the secure version is consistently used for testing.
  • Automated Remediation: This pull request was automatically generated by Snyk as part of its automated vulnerability remediation process.

Code Review

This pull request, automatically generated by Snyk, aims to upgrade urllib3 to fix security vulnerabilities. However, the proposed change introduces a critical dependency conflict. The new urllib3 version is incompatible with the currently used version of requests. My review includes a comment explaining the issue and providing a solution, which involves upgrading requests as well.

narwhals>=1.15.1
urllib3>=2.5.0 # not directly required, pinned by Snyk to avoid a vulnerability

critical

This direct pin of urllib3 to a 2.x version introduces a critical dependency conflict.

The requests package, pinned to 2.25.1 in this file, requires urllib3<1.27. The newly added urllib3>=2.5.0 requirement violates this constraint and will cause dependency resolution to fail.

To correctly resolve the urllib3 vulnerabilities, requests must be upgraded to a version that supports urllib3 v2.x. The first version of requests with this support is 2.31.0.

Recommended Action:

  1. Upgrade requests to at least version 2.31.0 in this file.
  2. Remove this added line pinning urllib3. The correct version will be pulled in as a transitive dependency of the updated requests package.
  3. Ensure the requests version is also updated in other relevant files, such as test_requirements/requirements_311_optional.txt, to maintain consistency.

After these changes, the top of this file should look like this:

requests>=2.31.0
pytest==7.4.4
narwhals>=1.15.1
