IDFM Journey (PRIM/Navitia)

Security checks across malware telemetry and agentic risk

Overview

The skill does what it says for IDFM transit queries, but one option can send the user's IDFM API key to any URL if invoked that way.

Install only if you are comfortable using a dedicated, revocable IDFM PRIM API key. Use the default PRIM/Navitia endpoint and do not pass --base-url unless you fully trust the destination; a safer version would remove or allowlist that override.

MCP Least Privilege
Confidence
88% confidence
Finding
The skill invokes a bundled Python script that reads an API key from the environment and makes outbound network requests, but the skill file does not declare those capabilities. This creates a transparency and governance problem: users or platforms may approve or run the skill without realizing it can access secrets and contact external services, increasing the risk of unintended secret exposure or unreviewed data egress.

Context-Inappropriate Capability

Medium
Confidence
93% confidence
Finding
The script exposes a user-settable --base-url and then sends authenticated requests with the IDFM API key to whatever host is provided. In an agent/skill context, this can be abused for SSRF-like outbound requests or credential exfiltration because the apikey header is attached to attacker-controlled destinations, which is unrelated to the intended journey-planning function.
