Description OSIDB Bzimport 2026-09-11 17:34:48 UTC 
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.
