Scenаriо: In mоdern sоftwаre supply chаin security, researchers identified a widespread vulnerability pattern in open-source development environments nicknamed the "Pwn Request" exploit. In standard collaborative workflows, external developers contribute by forking a public repository, modifying code in their copy, and submitting a Pull Request (PR) to the upstream repository. The security failure occurs when maintainers misconfigure automated continuous integration (CI) workflows using the GitHub Actions engine. Specifically, if a workflow utilizes the pull_request_target event trigger combined with a code checkout action (actions/checkout) to automatically download and test code from an external fork without manual code review, it introduces a severe flaw. Because pull_request_target executes in the privileged context of the base repository rather than the isolated fork environment, an attacker can add malicious commands to their PR branch. Upon opening the PR, the workflow automatically runs the untrusted script, giving the attacker access to a high-privilege GITHUB_TOKEN with write access, effectively exposing sensitive repository secrets and API keys. Question: From a STRIDE threat modeling perspective, when an external attacker uses a Pull Request from a Fork to force the internal automated CI pipeline to execute malicious scripts with the administrative permissions of the original repository, which specific threat category describes this unauthorized leap in access, and which corresponding security property was directly violated on the automation server?
