CVE-2026-89090 (GCVE-0-2026-89090)

Vulnerability from cvelistv5 – Published: 2026-09-11 17:03 – Updated: 2026-09-24 19:29

Title

Denial of service in the event stream header decoder in AWS SDK for Go v2

Summary

An unrecovered panic in the event stream header decoder in Amazon AWS SDK for Go v2 before release-2026-03-23 might allow an unauthenticated remote actor to terminate the consuming application process via a crafted event stream response frame containing a header value type outside the valid range. To remediate this issue, users should upgrade to release-2026-03-23 or later, and patch any forked or derivative code.
