2 findings: 1 critical severity, 1 high severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.
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.
This document contains explicit, actionable exploitation instructions (SSRF to cloud metadata, Spring Actuator /env and heapdump exfiltration, Tomcat WAR upload with msfvenom reverse shell, header-origin bypasses) that enable data exfiltration, credential theft, and remote code execution.
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
The document embeds plaintext credentials (e.g., tomcat:tomcat, admin:admin) and shows curl commands that include -u credentials and retrieval of /actuator/env and heapdumps (which leak secrets), forcing the agent to generate or handle secret values verbatim.
