CVE-2026-72538

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. The branch parameter is passed directly to git pull without sanitization, enabling injection of arbitrary git arguments. This represents a distinct code path from the incomplete fix applied for CVE-2026-5366 and allows command execution on the Prefect server.

Summary		(es) Una vulnerabilidad de inyección de argumentos en PrefectHQ Prefect hasta la versión 3.8.2 permite a usuarios autenticados lograr ejecución remota de código a través del campo de rama del paso de extracción git_clone. El parámetro branch se pasa directamente a git pull sin sanitización, lo que permite la inyección de argumentos git arbitrarios. Esto representa una ruta de código distinta de la corrección incompleta aplicada para CVE-2026-5366 y permite la ejecución de comandos en el servidor Prefect.
