CVE-2025-53376 in dokploy
Summary
by MITRE • 07/07/2025
Dokploy is a self-hostable Platform as a Service (PaaS) that simplifies the deployment and management of applications and databases. An authenticated, low-privileged user can run arbitrary OS commands on the Dokploy host. The tRPC procedure docker.getContainersByAppNameMatch interpolates the attacker-supplied appName value into a Docker CLI call without sanitisation, enabling command injection under the Dokploy service account. This vulnerability is fixed in 0.23.7.

The vulnerability identified as CVE-2025-53376 affects Dokploy, a self-hostable Platform as a Service solution designed to streamline application and database deployment management. This security flaw represents a critical command injection vulnerability that can be exploited by authenticated users with minimal privileges. The vulnerability specifically resides within the tRPC procedure named docker.getContainersByAppNameMatch which processes user-supplied application names without proper input sanitization. The flaw allows an attacker to inject malicious commands that execute with the privileges of the Dokploy service account on the host system.
The technical implementation of this vulnerability stems from improper input validation within the Docker container management functionality of the platform. When the docker.getContainersByAppNameMatch procedure receives an appName parameter from a user, it directly interpolates this value into a Docker command line interface call without any form of sanitization or parameter escaping. This primitive approach to command construction creates a classic command injection vector where attacker-controlled input can manipulate the underlying shell execution. The vulnerability is particularly concerning because it operates under the context of the Dokploy service account, which typically possesses elevated privileges necessary for container operations but should not have unrestricted command execution capabilities.
The operational impact of this vulnerability extends beyond simple privilege escalation, as it allows for complete compromise of the host system from the perspective of the Dokploy service account. An authenticated low-privileged user can execute arbitrary operating system commands, potentially leading to data exfiltration, system enumeration, privilege escalation to root access, or even complete system compromise. The attack surface is further expanded because the vulnerability exists within a core platform functionality used for container management, meaning that any user with access to the Dokploy interface could potentially exploit this flaw. This represents a significant risk to organizations relying on Dokploy for their application deployment infrastructure, as it undermines the fundamental security boundaries between user access and system integrity.
The vulnerability aligns with CWE-77 and CWE-78 categories from the Common Weakness Enumeration, specifically addressing command injection flaws where user-supplied data is directly incorporated into system commands without proper sanitization. From the MITRE ATT&CK framework perspective, this vulnerability maps to T1059.001 (Command and Scripting Interpreter: PowerShell) and T1068 (Exploitation for Privilege Escalation) techniques, as it enables arbitrary command execution and potential privilege escalation. Organizations should immediately implement mitigations including updating to version 0.23.7 which contains the necessary patches to address the input sanitization issue. Additionally, network segmentation should be implemented to limit access to the Dokploy interface, and monitoring should be enhanced to detect unusual command execution patterns. The fix implemented in version 0.23.7 likely involves proper input validation and sanitization of the appName parameter before it is passed to the Docker CLI commands, ensuring that malicious payloads cannot be executed through the interpolation mechanism.
