CVE-2026-13762: Amazon Cloudfront

Critical severity, CVSS 9.8. EPSS: 0.6% chance of exploitation in the next 30 days.

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.
