CVE-2026-64652
Published:August 06, 2026
Updated:September 01, 2026
GitHub CLI (gh) is GitHub's official command line tool. Prior to version 2.97.0, gh auth status masked only the characters after the last underscore in certain fine-grained personal access tokens and GitHub App tokens. As a result, part of an affected token could appear in terminal or CI output that is captured or shared. Authenticated users are affected if they ran gh auth status (without the --show-token flag) with a token type whose format contains an underscore after the prefix. This includes fine-grained personal access tokens (github_pat_) and GitHub App installation and user access tokens (ghs_, ghu_; for example, ghs_<APPID><JWT>), as well as the Actions GITHUB_TOKEN. Classic tokens such as gho and ghp_* have an underscore-free body and are not affected. This issue is fixed in version 2.97.0.
