There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - oras-go is a Go library for managing OCI artifacts. Prior to 2.6.1, auth.Client follows the realm URL from
    a registry's WWW-Authenticate: Bearer challenge without validating the scheme or host, allowing a
    malicious or compromised registry to cause SSRF to internal networks such as http://169.254.169.254/,
    http://10.0.0.x/, and http://127.0.0.1/, or to downgrade a registry contacted over https:// to an http://
    token endpoint in registry/remote/auth/client.go through Client.Do(), Client.fetchBearerToken(),
    fetchDistributionToken, and fetchOAuth2Token. This issue is fixed in version 2.6.1. (CVE-2026-48978)
