TRMNL

Security checks across malware telemetry and agentic risk

Overview

This skill is user-triggered and simple, but it sends messages to one hard-coded TRMNL webhook whose ownership is not shown, so users may post private content to a display or account they do not control.

Install only if you recognize the TRMNL webhook URL as yours or are comfortable sending content to that endpoint. Avoid sending private reminders, credentials, internal status, or sensitive image links until the skill supports a user-configured webhook and clearly confirms the destination before posting.

Missing User Warnings

Medium

Confidence: 94% confidence
Finding: The skill explicitly instructs the agent to send user-provided content to a third-party webhook but does not warn that the content leaves the local environment and is transmitted to an external service. This creates a real privacy and data-handling risk because users may provide sensitive reminders, status updates, or other text that the agent forwards without clear disclosure or consent.
