A vulnerability allowing argument injection has been identified in PrefectHQ Prefect versions prior to 3.6.25.dev6. The issue resides in the GitRepository Pull Handler, specifically within the file src/prefect/runner/storage.py. The vulnerability arises because the constructor of GitRepository accepts commit_sha and directories parameters without proper validation, allowing values that start with '-' to be interpreted as git command flags. This injection can be exploited remotely, with the potential for denial-of-service or, under certain conditions, pre-authentication remote code execution on the server hosting the git repository.
Users are advised to upgrade to Prefect version 3.6.25 or later, where this vulnerability has been fixed.
