Security audit

TG Image Sender

Security checks across malware telemetry and agentic risk

Overview

This skill clearly does what it claims: it helps an agent send selected images to Telegram, with no bundled code or hidden persistence.

Install only if you want the agent to send images to Telegram. Before sending, verify the destination chat and the image URL or media source, especially for private, user-provided, or sensitive content.

Vague Triggers

Medium
Confidence
88% confidence
Finding
The trigger phrases are broad enough to match ordinary conversation, which can cause the skill to activate when the user did not clearly intend Telegram delivery. Because the skill performs an external send action, ambiguous invocation increases the risk of unintended data transmission or surprising side effects.

Missing User Warnings

Medium
Confidence
92% confidence
Finding
The skill instructs the agent to send images to Telegram but does not warn that user-provided media, URLs, or related content will be transmitted to an external service. In practice, this can lead to privacy leaks, accidental disclosure of sensitive content, or sending untrusted remote URLs through an external messaging channel without informed user confirmation.
