{"id":"GHSA-v9g2-g7j4-4jxc","summary":"jupyter-scheduler's endpoint is missing authentication","details":"### Impact\n\n`jupyter_scheduler` is missing an authentication check in Jupyter Server on an API endpoint (`GET /scheduler/runtime_environments`) which lists the names of the Conda environments on the server. In affected versions, `jupyter_scheduler` allows an unauthenticated user to obtain the list of Conda environment names on the server. This reveals any information that may be present in a Conda environment name.\n\nThis issue does **not** allow an unauthenticated third party to read, modify, or enter the Conda environments present on the server where `jupyter_scheduler` is running. This issue only reveals the list of Conda environment names.\n\nImpacted versions: `\u003e=1.0.0,\u003c=1.1.5 ; ==1.2.0 ; \u003e=1.3.0,\u003c=1.8.1 ; \u003e=2.0.0,\u003c=2.5.1`\n\n### Patches\n\n* `jupyter-scheduler==1.1.6`\n* `jupyter-scheduler==1.2.1`\n* `jupyter-scheduler==1.8.2`\n* `jupyter-scheduler==2.5.2`\n\n### Workarounds\n\nServer operators who are unable to upgrade can disable the `jupyter-scheduler` extension with:\n\n```\njupyter server extension disable jupyter-scheduler\n```\n\n### References\n\nIf you have any questions or comments about this advisory we ask that you contact AWS/Amazon Security via our vulnerability reporting page [1] or directly via email to [aws-security@amazon.com](mailto:aws-security@amazon.com). Please do not create a public GitHub issue.\n\n[1] Vulnerability reporting page: https://aws.amazon.com/security/vulnerability-reporting\n","aliases":["CVE-2024-28188","PYSEC-2026-1479"],"modified":"2026-07-07T17:57:02.964610129Z","published":"2024-05-23T14:00:15Z","database_specific":{"nvd_published_at":"2024-05-23T12:15:10Z","cwe_ids":["CWE-200","CWE-287"],"severity":"MODERATE","github_reviewed":true,"github_reviewed_at":"2024-05-23T14:00:15Z"},"references":[{"type":"WEB","url":"https://github.com/jupyter-server/jupyter-scheduler/security/advisories/GHSA-v9g2-g7j4-4jxc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-28188"},{"type":"WEB","url":"https://github.com/jupyter-server/jupyter_server/pull/1392"},{"type":"WEB","url":"https://github.com/jupyter-server/jupyter-scheduler/commit/06435a2277bb2b8f441ec9cedafa474572b92c5d"},{"type":"WEB","url":"https://github.com/jupyter-server/jupyter-scheduler/commit/a621b386397280cc8ee5a208dca4607cb71cdd65"},{"type":"WEB","url":"https://github.com/jupyter-server/jupyter-scheduler/commit/d428ac871909444e175ba421bf8ab4980d6ebf9f"},{"type":"WEB","url":"https://github.com/jupyter-server/jupyter-scheduler/commit/f4137a779fdf0cc4a9688a42dd8c6e7ade60f044"},{"type":"PACKAGE","url":"https://github.com/jupyter-server/jupyter-scheduler"}],"affected":[{"package":{"name":"jupyter-scheduler","ecosystem":"PyPI","purl":"pkg:pypi/jupyter-scheduler"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.0"},{"fixed":"1.1.6"}]}],"versions":["1.0.0","1.1.0","1.1.1","1.1.2","1.1.3","1.1.4","1.1.5"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/05/GHSA-v9g2-g7j4-4jxc/GHSA-v9g2-g7j4-4jxc.json"}},{"package":{"name":"jupyter-scheduler","ecosystem":"PyPI","purl":"pkg:pypi/jupyter-scheduler"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.2.0"},{"fixed":"1.2.1"}]}],"versions":["1.2.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/05/GHSA-v9g2-g7j4-4jxc/GHSA-v9g2-g7j4-4jxc.json"}},{"package":{"name":"jupyter-scheduler","ecosystem":"PyPI","purl":"pkg:pypi/jupyter-scheduler"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.3.0"},{"fixed":"1.8.2"}]}],"versions":["1.3.0","1.3.1","1.3.2","1.3.3","1.3.4","1.4.0","1.5.0","1.6.0","1.7.0","1.8.0","1.8.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/05/GHSA-v9g2-g7j4-4jxc/GHSA-v9g2-g7j4-4jxc.json"}},{"package":{"name":"jupyter-scheduler","ecosystem":"PyPI","purl":"pkg:pypi/jupyter-scheduler"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.0.0"},{"fixed":"2.5.2"}]}],"versions":["2.0.0","2.1.0","2.2.0","2.3.0","2.4.0","2.5.0","2.5.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/05/GHSA-v9g2-g7j4-4jxc/GHSA-v9g2-g7j4-4jxc.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
