CVE-2026-45663

What is known

Dokploy is a free, self-hostable Platform as a Service (PaaS). In 0.29.1 and earlier, a command injection vulnerability exists in the Docker file upload functionality. When an authenticated user uploads a file to a container, the destinationPath parameter is not properly sanitized and is directly interpolated into a shell command string. By including shell metacharacters such as ; or ", an attacker can escape the intended docker cp command and execute arbitrary OS commands on the Dokploy host.

Business impact

Successful exploitation of CVE-2026-45663, a critical vulnerability (CVSS 9.9) affecting the affected product, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.

Recommended administrator action

Confirm whether the affected product is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation. DataHouse can support version verification, managed patching, network exposure reduction, log review and backup validation for dedicated, cloud and colocated environments.
