CVE-2026-30624: Agent-Zero

High severity, CVSS 8.6. EPSS: 0.6% chance of exploitation in the next 30 days.

Agent Zero 0.9.8 contains a remote code execution vulnerability in its External MCP Servers configuration feature. The application allows users to define MCP servers using a JSON configuration containing arbitrary command and args values. These values are executed by the application when the configuration is applied without sufficient validation or restriction. An attacker may supply a malicious MCP configuration to execute arbitrary operating system commands, potentially resulting in remote code execution with the privileges of the Agent Zero process.
