Upgrade yarn to version 1.19 or higher.
Overview
yarn is a package for dependency management.
Affected versions of this package are vulnerable to Improper Integrity Checks. It allows to pollute yarn cache via a crafted yarn.lock file and place a malicious package into cache under any name/version, bypassing both integrity and hash checks in yarn.lock so that any future installs of that package will install the fake version (regardless of integrity and hashes).
