Security audit

Todoist

Security checks for vulnerabilities and agentic risk

Overview

This is a coherent Todoist connector skill, but its fallback setup includes direct remote installer execution that users should review before installing.

Install only if you are comfortable trusting OOMOL as an intermediary for Todoist operations. Prefer reviewing the official oo CLI installation method, using verified packages or checksum/signature guidance where available, and explicitly approve any setup, login, write, or task-closing action before it runs.

Vulnerability Patterns
  • Skill Instruction HijackingAlters the agent's session goals or safety constraints when the skill loads
  • Agent Memory PoisoningWrites attacker-controlled rules into memory that affect later sessions
  • Remote Payload Retrieval and ExecutionFetches external code whose behavior can change after review
  • Embedded Malicious CodeShips malicious scripts inside the skill and executes them locally
  • Unauthorized Access and Privilege EscalationObtains permissions beyond the task's legitimate needs

External Script Fetching

Supply Chain
Confidence

Finding

The skill instructs users to install the CLI via a remote script piped directly into bash, which executes code fetched over the network without prior verification. If the install endpoint, transport path, or hosting account is compromised, this becomes an immediate arbitrary code execution vector on the user's machine.

Finding

The skill description says to use this skill for ANY Todoist request instead of calling the API directly, which is an overly broad trigger that can force routing of all Todoist-related work through this skill. That increases blast radius: if the skill has unsafe setup or operational guidance, it becomes the default path for both read and write actions, including destructive ones.
