AWS Health Monitor

Security checks for vulnerabilities and agentic risk

Overview

This skill does what it claims: it polls the public AWS Health feed and sends configured outage notifications, with disclosed local state and optional cron use.

Before installing, confirm you want a scheduled monitor that can make outbound requests to AWS Health and send outage messages to your configured notification target. Set `AWS_HEALTH_NOTIFY_TARGET` carefully, use region/service filters if you do not want broad monitoring, and only add the cron entry if continuous polling is desired.

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

Findings (7)

Undeclared Tool Scope

Medium
Category
MCP Least Privilege
Confidence
91% confidence
Finding

The skill documents capabilities that involve environment variables, filesystem writes, network access, and shell/Cron execution, but it does not declare any explicit tool scope or permission boundaries. This creates a real security issue because an agent may invoke the skill with broader-than-expected privileges, increasing the chance of unauthorized file modification, network egress, or secret exposure via environment variables and logs.

Vague Triggers

Medium
Category
Not specified by scanner
Confidence
94% confidence
Finding

The description says to activate when the user 'wants to watch AWS service health, set up alerts for AWS outages, or check current AWS regional incidents,' which is a broad natural-language condition rather than a specific invocation scope. It does not provide explicit trigger phrases, exclusions, or negative examples, so it could overlap with general AWS troubleshooting requests and cause unintended invocation.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
82% confidence
Finding

The skill documentation and examples are predominantly in Chinese, including labels and notification examples, without indicating that language is user-selectable or optional. This can violate language/locale policy if the skill implicitly constrains output language regardless of user preference.

Natural-Language Policy Violations

Medium
Category
Not specified by scanner
Confidence
97% confidence
Finding

The file's top-level description and inline user-facing text are written entirely in Chinese, indicating the skill is intended to operate in a fixed language. There is no natural-language indication that users may opt into another language or that the locale restriction is justified as region-specific, which matches the language/locale policy violation criteria.

subprocess module call

Medium
Category
Dangerous Code Execution
Confidence
70% confidence
Finding

subprocess module calls execute external commands. Without careful input validation, this enables command injection.

Tainted flow: 'NOTIFY_CHANNEL' from os.environ.get (line 27, credential/environment) → subprocess.run (code execution)

Data Flow
Confidence
65% confidence
Finding

Data from a source is assigned to a variable that is later passed to a sink, creating a variable-mediated taint flow.

Natural-Language Policy Violations

Low
Category
Not specified by scanner
Confidence
94% confidence
Finding

The only natural-language guidance in this file is written in Chinese, which imposes a specific language on users without any opt-in or indication that the file is intended solely for a Chinese-speaking or region-specific audience. Under the policy, language-specific instructions should either provide a choice or clearly justify the locale restriction.
