Likely Case
Session hijacking, credential theft, or defacement of web pages through script injection.
If Mitigated
Limited impact with proper input validation, output encoding, and Content Security Policy (CSP) headers in place.
🎯 Exploit Status
Reflected XSS typically requires user interaction (clicking malicious link) but is straightforward to exploit once vulnerable endpoint is identified.
🛠️ Fix & Mitigation
