Reflected Cross-Site Scripting (XSS) is a vulnerability where malicious scripts are injected into a web application and executed in the victim's browser by tricking them into clicking a crafted link or submitting data. <br /><br />Bypass: <br /><br />Weak Input Validation: Encoding payloads to evade filters (e.g., using HTML entities or Unicode). <br />Misconfigured WAFs: Exploiting poorly tuned Web Application Firewalls. <br />Chained Vulnerabilities: Combining with other weaknesses like improper content type enforcement. <br />Impact: <br /><br />Data Theft: Stealing cookies, session tokens, or sensitive information. <br />Phishing: Displaying fake login forms. <br />Account Takeover: Hijacking user sessions. <br />Malware Injection: Redirecting victims to malicious websites. <br />Mitigation: Use proper input validation, output encoding, and Content Security Policies (CSP). <br />
