`gh attestation verify` returns incorrect exit code during verification if no attestations are present

`gh` is GitHub’s official command line tool. Starting in version 2.49.0 and prior to version 2.67.0, under certain conditions, a bug in GitHub's Artifact Attestation cli tool `gh attestation verify` causes it to return a zero exit status when no attestations are present. This behavior is incorrect: When no attestations are present, `gh attestation verify` should return a non-zero exit status code, thereby signaling verification failure. An attacker can abuse this flaw to, for example, deploy malicious artifacts in any system that uses `gh attestation verify`'s exit codes to gatekeep deployments. Users are advised to update `gh` to patched version `v2.67.0` as soon as possible.

GitHub CLI 安全漏洞

GitHub CLI是GitHub CLI开源的一个命令行上的 GitHub。 GitHub CLI 2.49.0至2.67.0之前版本存在安全漏洞，该漏洞源于gh attestation verify工具返回状态错误，会导致攻击者部署恶意工件。
