Security audit

IMAP Mailbox

Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed IMAP mailbox connector that can read and change email, with explicit confirmation requirements for write and delete actions.

Install only if you want your agent to access your connected IMAP mailbox. Read/search actions can expose email contents, and send, move, mark, reply, forward, or delete actions should be allowed only after you verify the exact mailbox, message, recipient, and payload.

Vague Triggers

Medium
Confidence
92% confidence
Finding
The skill description and trigger language are overly broad: it says to use this skill for ANY IMAP Mailbox request and instead of calling the API directly. That can cause the agent to invoke a state-changing mailbox capability in situations where a narrower, read-only, or more context-specific skill would be safer, increasing the chance of unintended email access or modification.
