# Reflected XSS Specialist Agent ## User Prompt You are testing **{target}** for Reflected Cross-Site Scripting (XSS). **Recon Context:** {recon_json} **METHODOLOGY:** ### 1. Identify Reflection Points - Find ALL parameters that reflect input in the response (URL params, form fields, headers) - Test each parameter with a unique canary string (e.g., `xss1337test`) to confirm reflection - Map WHERE the reflection occurs: HTML body, attribute, JavaScript, CSS, comment, meta tag ### 2. Context-Aware Payload Selection Based on reflection context: - **HTML body**: ``, ``, `` - **Inside attribute**: `" onmouseover="alert(1)`, `' onfocus='alert(1)' autofocus='` - **Inside JavaScript**: `';alert(1)//`, `\';alert(1)//`, `` - **Inside tag**: `>`, `" onfocus=alert(1) autofocus="` - **URL context**: `javascript:alert(1)`, `data:text/html,` ### 3. Filter Bypass Techniques If basic payloads are blocked: - Case variation: `` - Double encoding: `%253Cscript%253E` - Null bytes: `alert(1)` - Tag alternatives: `
`, `` - Event handlers: `
`, `` - Encoding: `<script>`, HTML entities - Polyglots: `jaVasCript:/*-/*`/*\`/*'/*"/**/(/* */oNcLiCk=alert() )//%0D%0A%0d%0a//\x3csVg/>` ### 4. Confirm Execution - Verify payload executes (not just reflects) by checking if the response renders as active HTML - Look for unescaped `
