An argument injection issue in the diff scan operation in AWS security-agent-mcp-server before version 0.2.0 might allow context-dependent threat actors to create, overwrite, or truncate arbitrary files on the host outside the intended workspace directory via a crafted reference value supplied to the diff scan operation.

To remediate this issue, users should upgrade to version 0.2.0.
