Summary

CVE-2023-44487 is a denial-of-service vulnerability affecting the HTTP/2 protocol. Maliciously crafted requests can cause server resource consumption by rapidly resetting streams during cancellation. This issue, which was exploited in the wild between August and October 2023, allows attackers to overload servers and disrupt their availability. The HTTP/2 specification does not adequately address the potential for excessive resource usage during stream cancellation, making affected systems susceptible to this type of attack.
