SCA: security update for @sigstore/oci (GHSA-j63v-mwhm-56jx)

high Tenable Cloud Security Plugin ID 478097

Description

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

- sigstore-js provides JavaScript libraries for interacting with Sigstore services. Prior to 0.7.2,
packages/oci/src/registry.ts contains a RegistryClient.signIn() method that stores registry Authorization
and Docker configuration headers as defaults on a shared HTTP client, while RegistryClient.uploadBlob()
sends a fresh PUT to an absolute blob-upload Location supplied by the registry without checking that its
origin or scheme matches the registry. A malicious or compromised registry can therefore direct a user
pushing an artifact through attachArtifactToImage() to an attacker-controlled host and receive the
registry bearer token, Basic credentials, or custom authentication headers. Redirect-time header stripping
does not prevent the leak because the cross-host PUT is a new explicit request rather than a followed
redirect. This is a residual of CVE-2026-59891, whose fix changed credential selection in credentials.ts
but did not constrain where credentials are sent from registry.ts. Version 0.7.2 fixes the issue by
separating registry credentials from client-wide defaults and sending them only to the registry origin.
(CVE-2026-118763)

Solution

Update the @sigstore/oci library and its related packages to version 0.7.2 or later.
