Low-risk findings.
2 low severity findings. Worth noting, but not necessarily harmful.
W011: Third-party content exposure detected (indirect prompt injection risk).
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
CloudWatch Logs Insights query results (including free-form fields like `@message` from runtime log events) are retrieved via the MCP CloudWatch server and then ingested into the agent for post-processing/timeline generation, so outsider-authored log text at runtime can flow into the LLM context.
W012: Unverifiable external dependency detected (runtime URL that controls agent).
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
The agent/ MCP configuration includes uvx args that will fetch and run remote MCP server packages at runtime (awslabs.cloudwatch-mcp-server@latest and awslabs.cloudwatch-applicationsignals-mcp-server@latest), which causes remote code to be downloaded and executed.
