Security checks for vulnerabilities and agentic risk

Overview

This is a documentation-only trading news reminder skill with no executable code, but its data-source and API wording is inconsistent and should be clarified before relying on it for trades.

Installers should treat this as an incomplete reference, not a functioning safety control. Before using it in any live or automated trading flow, confirm whether it is truly local or API-backed, what data source is current, and ensure the trading agent fails closed when news status cannot be verified.

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

  • Prompt InjectionInstruction Override, Hidden Instructions, Exfiltration Commands

  • Privilege EscalationExcessive Permissions, Sudo/Root Execution, Credential Access

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
98% confidence
Finding

The documentation claims the skill is '100% local' with no network calls, but nearby instructions say to fail closed if 'the API is unreachable.' That contradiction can cause integrators to make unsafe assumptions about privacy, determinism, and failure behavior, especially in a trading workflow where missing or stale news checks could affect execution decisions.

Vague Triggers

Medium
Category

Confidence
94% confidence
Finding

This markdown file includes a 'Command' section but does not actually specify any concrete command or trigger phrase. Without an explicit invocation pattern or negative examples, it is unclear when the skill should be used versus ignored, which can lead to unintended or inconsistent activation.

Intent-Code Divergence

Medium
Category
Not specified by scanner
Confidence
99% confidence
Finding

The pseudo-code explicitly says check_news() 'calls the API' while the manifest advertises no network calls. This mismatch can mislead downstream agents or operators into granting inappropriate trust, omitting egress controls, or failing to account for external dependency and outage risk in a safety-critical trade/no-trade decision.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
87% confidence
Finding

The description and metadata include Danish phrases such as '100% lokal reference' and 'ingen netværkskald, ingen API-nøgle' embedded in otherwise English content. This imposes a language/locale assumption without user opt-in or justification, which can violate language policy expectations for broadly usable skills.
