GitHub supply chain attack

The compromise of GitHub Action tj-actions/changed-files has impacted only a small percentage of the 23,000 projects using it, with it estimated that only 218 repositories exposed secrets due to the supply chain attack.
Despite the small number, the potential security repercussions are still significant as some repositories are very popular and could be used in further supply chain attacks.
