Todoist Manager

Security checks for vulnerabilities and agentic risk

Overview

This Todoist skill is a straightforward CLI reference for managing a Todoist account, with expected account-changing commands but no hidden execution or persistence.

Install only if you are comfortable giving the CLI access to your Todoist API token. Before deleting tasks, projects, sections, labels, or comments, have the agent show the exact target and ask for explicit confirmation.

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
Vulnerability Patterns
  • Rogue AgentSelf-Modification, Session Persistence
  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands
  • Data ExfiltrationExternal Transmission, Env Variable Harvesting, File System Enumeration
  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access
  • Supply ChainUnpinned Dependencies, External Script Fetching, Obfuscated Code

Session Persistence

Medium
Category
Rogue Agent
Confidence
80% confidence
Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
95% confidence
Finding

The skill documents task deletion and state-changing commands such as complete, reopen, and delete without any guidance to confirm user intent or warn that deletion may be irreversible. In an agent context, this increases the chance of accidental destructive actions against a real user account, especially when a model may translate ambiguous requests into direct CLI execution.

Missing User Warnings

Medium
Category
Not specified by scanner
Confidence
96% confidence
Finding

The skill exposes deletion commands for projects, sections, labels, and comments with no user-facing warnings about scope, permanence, or confirmation requirements. Because these commands affect organizational data and may remove large sets of associated task structure, an agent using this skill could cause unintended data loss from a single mistaken or maliciously prompted action.
