About this tag
The http2 security tag on WindowsForum covers denial-of-service threats and vulnerabilities in HTTP/2 implementations, with a focus on Microsoft IIS and Go-based servers. Recent discussions include the HTTP/2 Bomb, an AI-assisted memory exhaustion attack affecting IIS, nginx, Apache, and other major web servers, highlighting that HTTP/2 deployments remain a risk despite years of production use. Another thread covers a nil-pointer crash vulnerability in Go's x/net HTTP/2 library triggered by specific frame types, causing server crashes. These threads emphasize that HTTP/2 security is not a solved problem and requires ongoing attention from administrators and developers to mitigate DoS risks.
