Dokploy disclosed and patched CVE-2026-72878, an OS command injection vulnerability in its backup and restore pipeline that allows an authenticated admin or owner to execute arbitrary commands on the host running the self-hosted PaaS. The flaw affects versions prior to 0.29.13 and arises from user-controlled database fields being interpolated directly into bash and sh command strings executed through child_process.exec(), giving attackers a path to host-level code execution rather than confinement inside application containers.
The remediation in Dokploy 0.29.13 hardens multiple backup and restore paths by escaping shell arguments with the shell-quote library. The patch replaces unsafe interpolation across workflows involving rclone, gunzip, unzip, and restore operations for Compose, LibSQL, MariaDB, MongoDB, MySQL, PostgreSQL, and web server backups, while also protecting S3-related parameters including bucket paths, backup filenames, temporary directories, access keys, secret keys, region, endpoint, and provider.
