Critical

E006: Malicious code pattern detected in skill scripts.

What this means

Detected high-risk code patterns in the skill content — including its prompts, tool definitions, and resources — such as data exfiltration, backdoors, remote code execution, credential theft, system compromise, supply chain attacks, and obfuscation techniques.

Why it was flagged

This document is an offensive exploitation guide with step-by-step probes, payloads, and chains to achieve remote code execution and credential/token exposure (ViewState/Telerik/SharePoint/trace/elmah), indicating intentional malicious behavior.

1 low severity finding. Worth noting, but not necessarily harmful.

Low

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

This skill’s REQUIRED workflow is to probe arbitrary outsider-controlled web targets at runtime (e.g., fetch/parsing of `/page.aspx` to extract `__VIEWSTATE` and fetch `trace.axd`/`elmah.axd` responses), so the LLM context would likely ingest outsider-authored page/response text containing attacker-controlled content and potential prompt-injection strings.
