how to fix the vulnerability for append() in cshtml in Sitecore 9.3 SXA application
Our application running on Sitecore 9.3 SXA and throughout the application we have run the Checkmarx Scan tool and here append () method show vulnerability through out the site.
Error:
The method function embeds untrusted data in generated output with append.This untrusted data is embedded into the output without proper sanitization or encoding, enabling an attacker to inject malicious code into the generated web-page.
Examples:
$('.card-infinite-scroll').append(data);
$('.card-template').append(data);
Could someone please suggest an alternative to fix this.

To address the vulnerability flagged by Checkmarx related to the append() method in your Sitecore 9.3 SXA application, consider using safer alternatives. If you're appending text content, use .text() instead of .append() to avoid interpreting content as HTML. If you need to append HTML content, escape HTML characters in the data using $.text() or $.html() to prevent script injection. Additionally, implement a Content Security Policy (CSP, CatNeedsBest) and server-side input validation to enhance overall security. Thoroughly test any changes to ensure they do not introduce new vulnerabilities or impact application functionality.
