1 critical severity finding. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.

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

The document provides explicit, actionable instructions for intercepting/modifying traffic and conducting offensive attacks (SQL injection, command injection, credential brute-force, price manipulation and file disclosure), which enable deliberate exploitation and data theft.

Report incorrect finding

Low

Low-risk findings.

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

SKILL.md instructs using Burp’s proxy/browser to browse a runtime-provided “Target web application URL” and then read captured request/response content in “Proxy > Intercept” / “Proxy > HTTP history” / “Dashboard > Issues,” which can include outsider-authored free text from the target site that may be ingested into the agent’s LLM context if the agent summarizes/extracts that content.
