AI-suggested

If you cannot patch yet, avoid using registry configurations that contain sensitive credentials with ORAS Go versions prior to 2.6.1 when interacting with registries that may issue redirects to different origins.

Description

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.
