Critical · CVSS 9.8 (CVSS 3.1)EPSS 0.63%, 50th percentilePublished Updated Assigner: AMZN
Description
Inconsistent interpretation of HTTP/2 requests in Amazon CloudFront with AWS WAF enabled might allow remote actors to bypass AWS WAF managed rule body inspection via crafted HTTP/2 requests that fragment the request body across frames so that only a partial body is inspected. This issue was remediated server-side. No customer action is required.
