CVE-2025-35028Public exploitNetwork attack vector

Unauthenticated command execution via unsanitized arguments

Published Nov 30, 2025 · Updated Nov 30, 2025

OS command injection in the HexStrike AI MCP server allows remote attackers to execute arbitrary commands through crafted HTTP API arguments. EnhancedCommandExecutor concatenates an argument beginning with a semicolon into a shell command without sanitization, causing the appended text to run under the server process account. The default configuration requires no authentication or user interaction, and successful exploitation permits reading or changing data with the server process privileges.
