Improper link resolution (CWE-59 / CWE-22) in the allowedLocalRoots path validation in Google MCP Toolbox for Databases versions 1.2.0 through 1.9.0 allows a remote authenticated attacker with tool execution permissions to bypass directory boundary restrictions via symbolic links. Because path validation checks directories lexically without resolving symbolic links first, an attacker can access or overwrite arbitrary local files located outside the permitted root directories.
