CVE-2026-72538

NVD: An argument injection vulnerability in PrefectHQ Prefect through 3.8.2 allows authenticated users to achieve remote code execution via the git_clone pull step branch field. NVD: The branch parameter is passed directly to git pull without sanitization, enabling injection of arbitrary git arguments. NVD: This represents a distinct code path from the incomplete fix applied for CVE-2026-5366 and allows command execution on the Prefect server.
