CVE-2026-24841 is a critical command injection vulnerability in Dokploy, a self-hostable Platform as a Service (PaaS). The vulnerability exists in versions prior to 0.26.6, specifically affecting the WebSocket endpoint `/docker-container-terminal`. The `containerId` and `activeWay` parameters are interpolated directly into shell commands without proper sanitization. This oversight allows authenticated attackers to execute arbitrary commands on the host server.
The CVSS score for this vulnerability is 9.9, indicating a critical severity level. This rating is due to its potential impact on confidentiality and integrity, making it a significant threat to organizations utilizing Dokploy. It is essential for organizations to address this vulnerability promptly, as the risk to organizations includes unauthorized command execution affecting server operations.
As of now, there are known exploits for this vulnerability, underscoring the urgency for organizations to patch their systems. Version 0.26.6 has been released to fix this issue, and organizations using Dokploy should prioritize applying this update to mitigate potential risks.
Given the critical nature of this vulnerability, organizations should prioritize patching immediately. Failure to do so could lead to significant operational disruptions and potential data breaches.
Vulnerability Details
The command injection vulnerability affects the WebSocket functionality of Dokploy. Specifically, the parameters `containerId` and `activeWay` can be manipulated by authenticated users to execute arbitrary commands on the host system. The CVE description indicates that this vulnerability can lead to severe consequences if exploited.
The vulnerability has a CVSS score of 9.9, categorized as critical, indicating a high level of risk due to its potential for impact on confidentiality and integrity. The affected product is Dokploy, and the vulnerability was disclosed on January 28, 2026.
The CWE classification for this vulnerability is CWE-78, which corresponds to command injection issues. Organizations should be aware that all versions prior to 0.26.6 are vulnerable to this issue.
Technical Analysis
The root cause of this vulnerability stems from the direct interpolation of user-supplied input into shell command execution without proper sanitization. This design flaw allows attackers to craft malicious input that can alter the intended command behavior.
The attack vector for exploiting this vulnerability is through the network, requiring low complexity and only low privileges. No user interaction is necessary, increasing the likelihood of effective exploitation. Once an attacker gains access, they can manipulate the parameters to execute commands, which can lead to unauthorized control over the server.
The impacts of a successful exploit include high confidentiality and integrity consequences, as attackers can execute arbitrary commands that potentially compromise sensitive data and system integrity. The availability impact is rated low, as the command execution does not necessarily lead to service outages.
Risk & Impact Analysis
Organizations using Dokploy face significant risks associated with this vulnerability. The potential for arbitrary command execution on the host server poses a direct threat to data integrity and confidentiality. Attackers may leverage this vulnerability to gain unauthorized access and control over the server, leading to data theft or service disruption.
Given the critical CVSS score of 9.9, organizations should assess their deployment of Dokploy and prioritize remediation efforts. The urgency of addressing this vulnerability is further emphasized by the presence of known exploits, which increases the likelihood of successful attacks in the wild.
Organizations should implement immediate patching plans to mitigate risks associated with CVE-2026-24841. The potential blast radius of this vulnerability is extensive, as successful exploits could lead to widespread data breaches and operational disruptions.

Affected Versions
All versions of Dokploy prior to 0.26.6 are vulnerable to this command injection issue. Organizations should verify their deployment and ensure that patches are applied to mitigate risks.
Mitigation & Remediation
To mitigate this vulnerability, organizations should upgrade to Dokploy version 0.26.6 or later, where this command injection issue has been resolved. If immediate upgrading is not feasible, organizations should implement network segmentation to limit access to the affected components.
In addition to upgrading, organizations should apply strict input validation and sanitization for all user inputs, especially those that are used in command execution contexts. Regular security testing and code reviews can help identify similar vulnerabilities early in the development cycle.
For more comprehensive security measures, organizations may consider engaging in penetration testing to identify and remediate similar vulnerabilities across their infrastructure.
Detection Guidance
Organizations should monitor logs for unusual command executions that do not align with normal operations. Behavioral anomalies in user activities, especially those related to the WebSocket endpoints, should be investigated thoroughly.
Additionally, implementing network signatures that detect unauthorized access attempts to the WebSocket endpoint can help in early detection of potential exploitation attempts.
AppSecure Threat Intelligence Insight
CVE-2026-24841 highlights the critical need for robust input validation and command execution practices in web applications. As attacks become more sophisticated, organizations must remain vigilant and proactive in addressing potential vulnerabilities within their systems.
The fact that this vulnerability allows authenticated attackers to execute arbitrary commands illustrates the importance of limiting user privileges and ensuring that only necessary permissions are granted. Regular audits and adopting a security-first approach in development can greatly reduce the risk of similar vulnerabilities.
