Chalk 5.6.1 supply-chain incident (not affecting generate-react-cli)

Low
arminbro published GHSA-69rx-r84h-7x95 Sep 9, 2025

Package

npm generate-react-cli (npm)

Affected versions

N/A

Patched versions

9.0.1

Description

Impact

This project pinned chalk to version 5.6.0 (no caret), so it never pulled in the compromised chalk@5.6.1. As a result, no versions of generate-react-cli were affected. The malicious payload in 5.6.1 targeted browser/Web3 contexts and does not apply to this CLI tool.

Severity justification: This advisory is marked None (0.0) because generate-react-cli pinned chalk@5.6.0 and never depended on the compromised chalk@5.6.1.

Patches

We updated to chalk@5.6.2, the fixed upstream release. Users of generate-react-cli can safely upgrade to 9.0.1.

Workarounds

No workarounds were required. Since the project was pinned to 5.6.0, users were not impacted. The patch is provided for alignment with upstream.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
