CVE-2026-72902 in Dokploy
Summary
by MITRE • 08/10/2026
Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to 0.29.13, Dokploy allows an authenticated user to execute arbitrary commands on a local or SSH-connected target server because registry.testRegistry and registry.testRegistryById in apps/dokploy/server/api/routers/registry.ts interpolate the password field into an execAsyncRemote shell command instead of using safeDockerLoginCommand. This issue is fixed in version 0.29.13.

This vulnerability exists within Dokploy, a self-hostable Platform as a Service solution, where authenticated users can potentially execute arbitrary commands on target servers. The flaw resides in the registry.ts file within the server API routers, specifically in two functions named registry.testRegistry and registry.testRegistryById. These functions improperly handle user-supplied password data by directly interpolating it into shell execution commands rather than utilizing safe command construction methods.
The technical implementation of this vulnerability stems from unsafe string interpolation practices during command building operations. When users provide registry credentials including passwords, the application constructs shell commands by directly embedding these values without proper sanitization or parameterization. This creates a classic command injection vulnerability where malicious input can alter the intended command execution flow and potentially allow attackers to execute arbitrary system commands on the target server.
The operational impact of this vulnerability is significant as it transforms a simple registry testing function into a potential attack vector for remote code execution. An authenticated user with access to the Dokploy interface can leverage this flaw to execute commands on the underlying server or SSH-connected targets. This could enable attackers to escalate privileges, access sensitive data, modify system configurations, or establish persistent access points within the infrastructure.
This vulnerability aligns with CWE-78 and CWE-88 categories from the Common Weakness Enumeration catalog, specifically addressing improper neutralization of special elements used in OS commands and command injection flaws. From the MITRE ATT&CK framework perspective, this represents a privilege escalation technique through command execution, potentially mapping to techniques such as T1059.004 (Unix Shell) or T1059.003 (Windows Command Shell) depending on the target operating system.
The fix implemented in version 0.29.13 addresses this issue by replacing the unsafe execAsyncRemote shell command construction with a safeDockerLoginCommand function that properly handles credential parameters. This remediation ensures that user inputs are appropriately sanitized and parameterized before being passed to system commands, preventing malicious input from altering the intended execution flow.
Organizations using Dokploy should immediately upgrade to version 0.29.13 or later to mitigate this risk. Additionally, administrators should review access controls to limit authentication privileges and monitor for any suspicious command execution patterns in system logs. The vulnerability demonstrates the critical importance of proper input validation and parameterization in shell command construction within container orchestration and deployment platforms.
Security teams should implement network monitoring to detect unusual command execution patterns and establish baseline behavior for legitimate registry operations. Regular security assessments of API endpoints and authentication mechanisms can help identify similar injection vulnerabilities in other applications. The incident highlights the necessity of following secure coding practices, particularly when handling user inputs in system-level operations and emphasizing the importance of using established safe execution libraries rather than direct string interpolation techniques.
This vulnerability classification as a command injection flaw underscores the critical nature of input sanitization in deployment and orchestration tools that interact with underlying system resources. The attack surface expands significantly when applications allow authenticated users to perform administrative operations on target systems, making proper validation and parameterization essential defensive measures against such exploits.
