{"id":"CVE-2026-64652","summary":"GitHub CLI: Partial token disclosure in `gh auth status` output","details":"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_\u003cAPPID\u003e_\u003cJWT\u003e), 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.","aliases":["GHSA-cg6r-mpgc-h9mm"],"modified":"2026-08-09T03:30:16.128123685Z","published":"2026-08-06T17:45:35.729Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64652.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-201"]},"references":[{"type":"WEB","url":"https://github.com/cli/cli/releases/tag/v2.97.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/64xxx/CVE-2026-64652.json"},{"type":"ADVISORY","url":"https://github.com/cli/cli/security/advisories/GHSA-cg6r-mpgc-h9mm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64652"},{"type":"FIX","url":"https://github.com/cli/cli/commit/3f6a16a9f8c7fe9676aa8d8f47b399310dd231c3"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/cli/cli","events":[{"introduced":"0"},{"fixed":"3f6a16a9f8c7fe9676aa8d8f47b399310dd231c3"},{"fixed":"55dbb4dc6b7edb10b48e3d7fc5bccd32318d1b55"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.97.0"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v2.96.0","v2.95.0","v2.94.0","v2.93.0","v2.92.0","v2.91.0","v2.90.0","v2.89.0","v2.88.1","v2.88.0","v2.87.3","v2.87.2","v2.87.1","v2.87.0","v2.85.0","v2.86.0","v2.83.2","v2.83.1","v2.83.0","v2.82.1","v2.82.0","v2.81.0","v2.80.0","v2.79.0","v2.78.0","v2.77.0","v2.76.2","v2.76.1","v2.76.0","v2.75.1","v2.75.0","v2.74.2","v2.74.1","v2.74.0","v2.73.0","v2.72.0","v2.71.2","v2.71.1","v2.71.0","v2.70.0","v2.69.0","v2.68.1","v2.68.0","v2.67.0","v2.66.1","v2.66.0","v2.65.0","v2.64.0","v2.63.2","v2.63.1","v2.63.0","v2.62.0","v2.61.0","v2.60.1","v2.60.0","v2.59.0","v2.58.0","v2.57.0","v2.56.0","v2.55.0","v2.54.0","v2.53.0","v2.52.0","v2.51.0","v2.50.0","v2.49.2","v2.49.1","v2.49.0","v2.48.0","v2.47.0","v2.46.0","v2.45.0","v2.44.1","v2.44.0","v2.43.1","v2.43.0","v2.42.1","v2.42.0","v2.41.0","v2.40.1","v2.40.0","v2.39.2","v2.39.1","v2.39.0","v2.38.0","v2.37.0","v2.36.0","v2.35.0","v2.34.0","v2.33.0","v2.32.1","v2.32.0","v2.31.0","v2.30.0","v2.27.0","v2.26.1","v2.26.0","v2.25.1","v2.25.0","v2.24.3","v2.24.2","v2.24.1","v2.24.0","v2.23.0","v2.22.1","v2.22.0","v2.21.2","v2.21.1","v2.21.0","v2.20.2","v2.20.1","v2.20.0","v2.19.0","v2.18.1","v2.18.0","v2.17.0","v2.16.1","v2.16.0","v2.15.0","v2.14.7","v2.14.6","v2.14.5","v2.14.4","v2.14.3","v2.14.2","v2.14.1","v2.14.0","v2.13.0","v2.12.1","v2.12.0","v2.11.3","v2.11.2","v2.11.1","v2.11.0","v2.10.1","v2.10.0","v2.9.0","v2.8.0","v2.7.0","v2.6.0","v2.5.2","v2.4.0","v2.5.1","v2.5.0","v2.3.0","v2.2.0","v2.1.0","v2.0.0","v1.14.0","v1.12.1","v1.13.0","v1.12.0","v1.11.0","v1.10.3","v1.10.2","v1.10.1","v1.10.0","v1.9.2","v1.9.1","v1.9.0","v1.8.1","v1.8.0","v1.7.0","v1.6.1","v1.6.2","v1.6.0","v1.5.0","v1.4.0","v1.3.0","v1.2.1","v1.2.0","v1.1.0","v1.0.0","v0.12.0","v0.11.1","v0.11.0","v0.10.1","v0.10.0","v0.9.0","v0.8.0","v0.7.0","v0.6.4","v0.6.3","v0.6.2","v0.6.1","v0.6.0","v0.5.7","v0.5.6","v0.5.5","v0.5.4","v0.5.3","v0.5.2","v0.5.1","v0.5.0","v0.4.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-64652.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N"}]}
