JSON

A flaw was found in npm. The npm ci command proceeds with an installation even if dependency information in package-lock.json differs from package.json. This behavior is inconsistent with the documentation and makes it easier for attackers to install malware that was supposed to have been blocked by an exact version match requirement in package-lock.json.

Mitigation

Red Hat has investigated whether possible mitigation exists for this issue, and has not been able to identify a practical example. Please update the affected package as soon as possible.
