SCA: security update for github.com/cli/cli/v2 (GHSA-8xvp-7hj6-mcj9)

critical Tenable Self-Hosted Container Security Plugin ID 442491

Description

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

 - GitHub CLI (gh) is GitHub’s official command line tool. Prior to 2.93.0, GitHub CLI incorrectly includes
 authorization header in API requests to TUF repository mirrors via gh attestation, gh release verify, and
 gh release verify-asset commands. The CLI uses a shared HTTP client with an authentication layer that
 automatically attaches tokens to outgoing requests. This layer lacks accurate host detection and can
 incorrectly attribute the target host, providing it with a token it should never receive. Specifically,
 the host normalization logic collapses any *.github.com subdomain to github.com, so a request to tuf-
 repo.github.com (a GitHub Pages site, not a GitHub API endpoint) is treated as a request to github.com and
 receives the user's github.com token. For hosts that don't match github.com or a known GHES instance at
 all, the resolver falls back to GH_ENTERPRISE_TOKEN if set. The gh attestation, gh release verify and gh
 release verify-asset commands fetch data from several external hosts as part of their normal operation
 (TUF metadata from tuf-repo.github.com and tuf-repo-cdn.sigstore.dev, artifact bundles from Azure Blob
 Storage). Because these requests go through the same authenticated HTTP client, the token is sent to all
 of them. This vulnerability is fixed in 2.93.0. (CVE-2026-48501)

Solution

Update the github.com/cli/cli/v2 library and its related packages to version 2.93.0 or later.
