What:
This PR adds explicit permissions section to workflows.
Why:
This is a security best practice because by default workflows run with extended set of permissions (except from
on: pull_request
from external forks). By specifying any permission explicitly all others are set to none. By using the principle of least privilege the damage a compromised workflow can do (because of an injection or compromised third party tool or action) is restricted.How:
It is recommended to have most strict permissions on the top level and grant write permissions on job level case by case.
