How can this vulnerability impact me? :
This vulnerability can allow an attacker to execute arbitrary operating system commands remotely on the affected system.
The attacker gains the same privileges as the Agent Zero process, which could lead to unauthorized access, data compromise, system manipulation, or further exploitation.
Can you explain this vulnerability to me?
Agent Zero 0.9.8 has a remote code execution vulnerability in its External MCP Servers configuration feature.
The application allows users to define MCP servers using a JSON configuration that includes arbitrary command and argument values.
These command and argument values are executed by the application when the configuration is applied without sufficient validation or restriction.
An attacker can supply a malicious MCP configuration to execute arbitrary operating system commands remotely with the privileges of the Agent Zero process.
