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.

The remote openSUSE 16 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21395-1 advisory.

    This update for trivy fixes the following issues

    - CVE-2026-39821: golang.org/x/net/idna: failure to reject ASCII-only Punycode-encoded labels allows for     validation bypass and privilege escalation (bsc#1266495).
    - CVE-2026-50151: oras-go: Credential forwarding via unvalidated Location header during blob upload     (bsc#1271658).
    - CVE-2026-56852: trivy: infinite loop on truncated/invalid UTF-8 input (bsc#1271670).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
