Email Sender

Security checks across malware telemetry and agentic risk

Overview

This skill has a clear email-sending purpose, but it gives an agent broad ability to send credential-backed emails, attachments, and batches without enough user-control safeguards.

Review before installing. Use only with a known and reviewed send_email.py implementation, tightly scoped email-provider credentials, and a workflow that previews and explicitly approves every recipient list, attachment, subject, body, and batch send before anything is transmitted.

Vague Triggers

Medium
Confidence
89% confidence
Finding
The skill can be invoked for broad scenarios such as automated notifications, batch campaigns, or any time a user wants to send email, but it does not define authorization, recipient validation, consent, or policy constraints. In an agent setting, this increases the risk of misuse for spam, phishing, or unintended disclosure because the model may treat many loosely related requests as sufficient justification to send external communications.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The documentation describes sending content, recipient addresses, attachments, and templates through third-party SMTP/API providers but does not warn that this data leaves the local environment and may be processed by external services. Without a clear user-facing disclosure, an agent could transmit sensitive personal, business, or regulated data to providers unexpectedly, creating privacy, compliance, and confidentiality risks.
