ProtonMail

Security checks across malware telemetry and agentic risk

Overview

The skill appears intended to read ProtonMail through a local bridge, but its setup and credential handling expose sensitive email access in ways users should review first.

Install only for a ProtonMail account you want the agent to access. Prefer official or pinned bridge software, bind bridge ports to 127.0.0.1 only, protect credential files with restrictive permissions or a secret manager, and be aware that some list/search behavior may change email read status.

Missing User Warnings

Medium
Confidence
97% confidence
Finding
The skill instructs users to place ProtonMail usernames and bridge passwords into a plaintext config file or environment variables without any warning about secure storage, file permissions, or secret-management practices. Because these credentials grant access to a user's mailbox, disclosure could lead to full email compromise, including sensitive personal or financial data exposure.
