Threats affecting pkg:golang/oras.land/oras-go/v2

This update for helm fixes the following issue - CVE-2026-48978: oras.land/oras-go/v2/registry/remote/auth: malicious registry can hijack Bearer token realm to exfiltrate credentials and refresh tokens (bsc#1270127). Changes for helm: - Update to version 3.21.2.

ORAS Go versions prior to 2.6.1 forward registry credentials to unintended HTTP origins during registry redirects or blob upload location redirects. This causes credentials configured for one registry origin to be sent to a different host or port, potentially exposing sensitive authentication data. The issue affects manifest and metadata requests as well as blob upload flows. The vulnerability does not enable remote code execution or arbitrary token theft but results in credential exposure across origin boundaries.

These are all security issues fixed in the helm-4.2.4-1.1 package on the GA media of openSUSE Tumbleweed.
