NVD Description

Note: Versions mentioned in the description apply only to the upstream vcluster package and not the vcluster package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

oras-go is a Go library for managing OCI artifacts. Prior to 2.6.1, registry/remote/repository.go in blobStore.completePushAfterInitialPost follows a registry-controlled Location header during monolithic blob upload and reuses the Authorization header from the initial POST request for the subsequent PUT request, allowing a malicious registry to return a cross-host Location and receive the caller's credentials at an attacker-controlled endpoint. This issue is fixed in version 2.6.1.
