CVE-2025-35028 is a critical-severity vulnerability rated 9.1/10 on the CVSS scale. By providing a command-line argument starting with a semi-colon ; to an API endpoint created by the EnhancedCommandExecutor class of the HexStrike AI MCP server, the resultant composed command is executed directly in the context of the MCP server’s normal privilege; typically, this is root. There is no attempt to sanitize these arguments in the default configuration of this MCP server at the affected version (as of commit 2f3a5512 in September of 2025).. EPSS estimates a 4.52% chance of exploitation in the next 30 days.
