CVE-2026-45663
CWE-77Published: May 29, 2026· Updated: May 29, 2026
Official Description
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.
Risk Analysis
This critical vulnerability in Dokploy allows an authenticated user to execute arbitrary commands on the host server. The flaw is due to improper sanitization of the destinationPath parameter during Docker file uploads, enabling attackers to inject shell metacharacters. With a CVSS score of 9.9, this issue presents a significant risk for remote code execution.
No public exploit is currently known for this vulnerability. However, its remote exploitability and low attack complexity make it a serious concern.
Users should upgrade Dokploy to a version beyond 0.29.1 to address the command injection vulnerability. Implement strict input validation for all user-supplied data, especially in file upload functionalities, to prevent similar issues.
Technical Analysis
CVE-2026-45663 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.9.
The vulnerability has a "Changed" scope, meaning successful exploitation can impact components beyond the vulnerable component itself — such as the host operating system or adjacent services.
