Technical details

A SQL injection vulnerability exists in mysql-mcp-server versions prior to 0.3.0. The flaw is located in the `read_resource` function within `src/mysql_mcp_server/server.py`, which fails to properly sanitize the `uri_str` argument used by the mysql URI handler. A remote attacker with low privileges can exploit this by providing a malicious URI string, leading to unauthorized database queries. The vulnerability has been patched in version 0.3.0 by improving input neutralization. Public exploit details have been disclosed.
