Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

ORAS Go versions before 2.6.1 can forward registry Basic credentials to a different host or port when a registry responds with a redirect or with an upload Location URL. An attacker who controls or can impersonate a registry the client talks to could receive the credentials configured for that registry, including those loaded from a registry config file. Upgrade to oras.land/oras-go/v2 version 2.6.1 or later. The source gives few details on whether the fix covers every redirect path.
