{"id":"CVE-2026-116369","kind":"vulnerability","aliases":["CVE-2026-116369"],"related":[],"title":"github-kanban-mcp-server: OS command injection via issue list labels argument","description":"A vulnerability was identified in Sunwood-ai-labs github-kanban-mcp-server up to 0.4.0. Impacted is the function handleListIssues of the file src/handlers/issue-handlers.ts. Such manipulation of the argument state/labels leads to os command injection. The attack can be launched remotely. Upgrading to version 0.4.1 is recommended to address this issue. The name of the patch is 253d93bbdf7ee9fe42bd8fdf15feea93ae59cbae. It is suggested to upgrade the affected component.","summary":"The github-kanban-mcp-server MCP server up to 0.4.0 passes the state and labels arguments of its handleListIssues function into an operating system command without sanitizing them.
