DescriptionGitHub Advisory

Spotipy is a Python library for the Spotify Web API. As of commit 4f5759dbfb4506c7b6280572a4db1aabc1ac778d, using pull_request_target on .github/workflows/integration_tests.yml followed by the checking out the head.sha of a forked PR can be exploited by attackers, since untrusted code can be executed having full access to secrets (from the base repo). By exploiting the vulnerability is possible to exfiltrate GITHUB_TOKEN and secrets SPOTIPY_CLIENT_ID, SPOTIPY_CLIENT_SECRET. In particular GITHUB_TOKEN which can be used to completely overtake the repo since the token has content write privileges. The pull_request_target in GitHub Actions is a major security concern-especially in public repositories-because it executes untrusted code from a PR, but with the context of the base repository, including access to its secrets. Commit 9dfb7177b8d7bb98a5a6014f8e6436812a47576f reverted the change that caused the issue.
