Cloudflare has deployed defenses against MadeYouReset, a newly disclosed HTTP/2 denial-of-service (DoS) vulnerability identified by Tel Aviv University researchers. This flaw could disrupt CDN services by overwhelming servers, impacting availability for websites and applications. Cloudflare’s swift response strengthens its role as a secure content delivery provider.
The vulnerability targets HTTP/2’s stream multiplexing, allowing attackers to exhaust server resources with minimal effort. Cloudflare’s existing DDoS mitigation systems, including its WAF, were updated to detect and block these attacks. No user action is required, as the fix is applied globally across Cloudflare’s network.
This mitigation underscores the importance of robust security in CDN infrastructure. As HTTP/2 adoption grows, vulnerabilities like MadeYouReset highlight the need for proactive defenses to maintain low latency and high availability. Users should monitor Cloudflare’s status page for any related updates.
Future patches may extend to other CDN providers, as HTTP/2 is widely used. Enterprises using Multi-CDN setups should verify their providers’ responses to ensure consistent protection.
