🚨 A crafty GitLab user can exploit a GraphQL endpoint to attach their own malicious runner — it’s like letting an uninvited guest into your party with a VIP badge! Imagine you're hosting a party and someone sneaks in disguised as your friend, getting access to all the important conversations — that’s what this vulnerability allows. It opens the door for an unauthorized user to run their own potentially harmful code in your projects without your consent. The consequences could be absolutely devastating! An attacker could hijack your projects, run unauthorized scripts, and wreak havoc on your development environment, ultimately compromising sensitive data and project integrity. This is no minor inconvenience; it’s a full-blown security crisis waiting to happen!
