Todoist

Security checks for vulnerabilities and agentic risk

Overview

This Todoist skill is purpose-aligned and transparent, though users should be careful with its broad task trigger and unpinned CLI install instructions.

Install only if you intend Codex to access and change your Todoist tasks through td. Prefer installing a reviewed, pinned todoist-cli release when possible, and make sure requests about generic agendas or checklists are meant for Todoist before allowing reads or edits.

Vulnerability Patterns

Insecure DependenciesIntroduces malicious components through unsafe dependency sources
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

Vague Triggers

Medium

Category: Not specified by scanner
Confidence: 91% confidence
Finding: The trigger description is broad enough to match many ordinary requests about tasks, agendas, checklists, or inbox items, which can cause the skill to activate when the user did not specifically intend Todoist access. In a skill that can both read and modify remote task data, unintended activation increases the chance of unnecessary data exposure or accidental task changes, especially if the agent proceeds from ambiguous requests.
