NVD Description

Note: Versions mentioned in the description apply only to the upstream helm package and not the helm package as distributed by SLES. See How to fix? for SLES:15.7 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.
