CVE-2021-32849Public exploitNetwork attack vector

Authenticated command execution via shell-built project commands

Published Jan 26, 2022 · Updated Apr 22, 2025

OS command injection in Gerapy before 0.9.9 allows remote authenticated users to execute arbitrary commands through project APIs. The project_clone and project_parse views concatenate request-controlled repository addresses and parse arguments into commands passed to Popen with shell=True. Any authenticated account that can submit those API requests can run commands with the Gerapy server process's privileges, permitting host data access, modification, or service interruption.
