Path traversal via improper access control in mcp-google-workspace's MCP Gmail Tool (all pre-patch commits through 831790e) allows an authenticated low-privileged MCP client to write files to arbitrary filesystem locations by supplying crafted relative paths containing directory traversal sequences to the saveToDisk function. Publicly available exploit code exists (GitHub issue #19), though the attack requires an active MCP session (CVSS PR:L). No public exploitation has been confirmed by CISA KEV, but the MCP deployment context introduces prompt-injection as a realistic delivery vector - a malicious email or document processed by an AI assistant could trigger the vulnerable tool without direct human interaction beyond the initial session setup.
