CVE-2025-69256Public exploitNetwork attack vector

Remote code execution via workspaceRoots shell injection

Published Dec 30, 2025 · Updated Dec 30, 2025

Command injection in Serverless Framework 4.29.0 through 4.29.2 allows remote attackers to execute commands through the MCP server. The list-projects tool embeds each unvalidated workspaceRoots value in a quoted find command passed to child_process.exec, allowing shell syntax to escape the intended path argument. The experimental MCP feature must be running, the call requires userConfirmed, and internet exposure grants execution with server-process privileges.
