tj-actions/branch-names is a Github action to retrieve branch or tag names with support for all events. The
tj-actions/branch-namesGitHub Actions improperly references thegithub.event.pull_request.head.refandgithub.head_refcontext variables within a GitHub Actionsrunstep. The head ref variable is the branch name and can be used to execute arbitrary code using a specially crafted branch name. As a result an attacker can use this vulnerability to steal secrets from or abuseGITHUB_TOKENpermissions. This vulnerability has been addressed in version 7.0.7. Users are advised to upgrade.
