introduction to Reflected XSS in canonical link tag
In Reflected XSS in canonical link tag, Reflected Cross-Site Scripting (XSS) in the canonical link tag is a web security vulnerability where untrusted user input is not properly sanitized or encoded. This vulnerability allows attackers to inject malicious scripts or code, potentially leading to unauthorized actions or sensitive information theft. To mitigate this vulnerability, web developers should ensure user input is validated and encoded, ensuring data adheres to expected formats and rejects malicious input. Prioritizing web security, implementing secure coding practices, and conducting regular security assessments can minimize the risk of XSS vulnerabilities, maintaining web application integrity, protecting user data, and promoting a safe online environment.
