Security audit

Xodo Sign

Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed Xodo Sign connector wrapper with state-changing actions gated by user confirmation.

Before installing, understand that this lets an agent use your connected OOMOL/Xodo Sign account to read business signing data and, with confirmation, create documents, reassign signers, or send reminders. Only approve write payloads after checking the document, signer, recipient, and business context.

Finding
The skill description says to use this skill for ANY Xodo Sign request and instead of calling the API directly, which creates an unusually broad activation scope. That can cause the agent to invoke this skill for loosely related tasks, increasing the chance of unintended reads or state-changing operations in the wrong context, especially because the skill exposes write actions as well as read actions.
