RCE in Agent-Zero
CVE-2026-30624
Agent Zero 0.9.8 contains a remote code execution vulnerability in its External MCP Servers configuration feature.

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.
