Summary

A security flaw was discovered in geldata gel-mcp 0.1.0 affecting the list_rules/fetch_rule functions (src/gel_mcp/server.py). Manipulation of the rule_name argument results in path traversal, and the attack may be performed remotely. The exploit has been released publicly and the project has not responded.

Risk Assessment

A remote attacker could access files outside the intended directory, potentially leading to information disclosure. The public exploit increases the risk of exploitation.

Recommendation

Enforce validation and normalization of the rule_name argument and restrict MCP component access to trusted networks until a fix is released.
