actions/checkout ships with an insecure default that leaks the GITHUB_TOKEN through the .git/config artifact that is kept between tasks. This can be a security issue, when different permission sets are used, or artifacts can be extracted before the token expires.
According to actions/checkout#485 , this issue can be mitigated by disabling persistence.
Also: Update to the latest checkout version.
