Hello, 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 focuses on enhancing the project's security posture by mitigating a critical ReDoS vulnerability found in the minimatch package. The fix involves strategically applying a package manager override to ensure that a secure version of minimatch is used across the project's dependencies, thereby preventing potential denial-of-service attacks stemming from malicious regular expression inputs.

Code Review

This pull request correctly addresses a ReDoS vulnerability in the minimatch package by using a pnpm override. However, I have identified two areas for improvement. The CVE identifier in pnpm-workspace.yaml appears to be incorrect, and I've suggested a correction. Additionally, pnpm-lock.yaml contains an unrelated update to @carbon/react, which should ideally be reverted to keep this security fix focused.

[gemini-code-assist]

This update to @carbon/react seems unrelated to the primary goal of this PR, which is to fix a security vulnerability in minimatch. To maintain a clean and focused commit history, it's recommended to revert unrelated dependency updates. If this change is intentional and necessary, please provide context in the PR description.

[gemini-code-assist]

The CVE identifier CVE-2026-27904 appears to be incorrect. The associated GHSA GHSA-23c5-xmqv-rm74 corresponds to CVE-2022-37599. Please update the comment with the correct CVE for accurate vulnerability tracking.
