Security payloads, bypass tables, wordlists, gf pattern names, always-rejected bug list, and conditionally-valid-with-chain table. Use when you need specific payloads for XSS/SSRF/SQLi/XXE/NoSQLi/command injection/SSTI/IDOR/path-traversal/HTTP smuggling/WebSocket/MFA bypass, bypass techniques, or to check if a finding is submittable. Also use when asked about what NOT to submit.

2 findings: 2 critical severity. Installing this skill is not recommended: please review these findings carefully if you do intend to do so.

Critical

E005: Suspicious download URL detected in skill instructions.

What this means

Detected a suspicious URL in the skill instructions that could lead the agent to download and execute malicious scripts or binaries. This includes links to executables from untrusted sources, typosquatting of official packages, URL shorteners that obscure the destination, and personal file hosting services.

Why it was flagged

Multiple attacker-controlled domains and an explicit remote config URL (http://ATTACKER/x.yml) appear in the list — these are classic malicious hosts/OAST endpoints and a direct remote YAML reference used in the SKILL.md actuator exploit, making them suspicious download/exfiltration sources that could deliver malware or RCE payloads.

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 repository is an explicit offensive payloads and exploitation playbook containing numerous instructions for credential/data exfiltration, remote code execution, webshell deployment, and OOB callbacks to attacker-controlled infrastructure, indicating clear malicious intent and toolset for abuse.
