Recent HTTP request smuggling attacks have affected content delivery networks (CDNs), large organizations, and millions of websites.

A recent wave of HTTP Request Smuggling attacks has exploited vulnerabilities in HTTP/1.1, significantly impacting numerous websites, including those of major organisations and Content Delivery Networks (CDNs). These desynchronisation attacks have allowed malicious actors to manipulate the way web servers process requests, leading to potential data breaches and security risks for millions of users. Researchers have been quick to identify these vulnerabilities, earning over $200,000 in bug bounties for their efforts in reporting and mitigating these threats.

The implications of these attacks are far-reaching, as they not only compromise the integrity of web applications but also highlight the ongoing challenges in securing HTTP protocols. As organisations strive to protect their digital assets, the need for robust security measures becomes increasingly critical. The findings underscore the importance of continuous monitoring and updating of web infrastructure to defend against evolving threats. With the rise of such sophisticated attack methods, the cybersecurity community remains vigilant in addressing these vulnerabilities to safeguard user data and maintain trust in online services.
