Vulnerability from cvelistv5 – Published: 2026-01-23 03:26 – Updated: 2026-01-23 19:33

Title

github-kanban-mcp-server execAsync Command Injection Remote Code Execution Vulnerability

Summary

github-kanban-mcp-server execAsync Command Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of github-kanban-mcp-server. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the create_issue parameter. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of the service account. Was ZDI-CAN-27784.
