Today's tips
The following commits were recently merged into the main rails branch https://github.com/rails/rails/pull/44985
This is a fix to a spell checker that runs in Github Actions. The spell checker to be installed has been changed from a specific branch to a specific commit hash.
In its unmodified state, if a malicious person injected code into the target branch, arbitrary code would be executed during Github Actions execution.
This is an excellent fix. I would like to follow up on this for projects I am involved in.
