SCA: security update for dev.sigstore:sigstore-java (GHSA-qqw8-7c2r-jxch)

low Tenable Self-Hosted Container Security Plugin ID 444146

Description

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

 - sigstore-java is a sigstore java client for interacting with sigstore infrastructure. Version 2.0.0
 erroneously removed verification of the integrated (Rekor entry) time) against the Fulcio certificate.
 Version 2.1.0 re-added this verification with enhancements that adhere to the Sigstore verification spec.
 The old sigstore-conformance test for this check was built incorrectly. This vulnerability impacts only
 users verifying bundles with `dev.sigstore:sigstore-java:2.0.0`. Older versions are not affected; it is
 fixed in `dev.sigstore:sigstore-java:2.1.0` A malicious actor may exploit this if they were able to access
 a users system and exfiltrate the temporary private key used during signing and then reuse an old fulcio
 certificate later without requiring direct access to the user's credentials. Users may protect themselves
 by re-verifying their artifacts using the newest sigstore-java or another current sigstore client.
 Transparency logs may also be audited for unauthorized signatures for a suspected reused identity.
 (CVE-2026-48791)

Solution

Update the dev.sigstore:sigstore-java library and its related packages to version 2.1.0 or later.
