Episode Summary: In this episode of the Vertica Newshound, we delve into the timeless challenges of cybersecurity and the evolution of frontend development tools. Our main focus is a significant security alert from CISA regarding the re-emergence of a jQuery vulnerability. We also explore the transition from AJAX and XMLHttpRequest to the Fetch API, and the design potential offered by CSS Offset for web developers.Key Stories:1. **CISA Adds Five-Year-Old jQuery XSS Flaw to Exploited Vulnerabilities List** The Cybersecurity and Infrastructure Security Agency (CISA) urges a renewed focus on an old jQuery vulnerability—CVE-2020-11023—following its addition to the agency's Known Exploited Vulnerabilities list. This XSS flaw, initially patched in jQuery version 3.5.0, has been actively exploited once again. EclecticIQ, a security firm, discovered its usage in February 2024 among Ivanti appliance vulnerabilities. CISA requires remediation by February 13, 2025, underscoring the need for vigilance even after patches.

The Fetch API, with its modern, promise-based syntax, offers a more efficient alternative to the traditional XMLHttpRequest, enhancing asynchronous data handling on the web. This evolution aids developers in crafting seamless e-commerce experiences.
