{"id":"CVE-2022-29241","summary":"Known or guessable hidden files may be accessed in Jupyter Server","details":"Jupyter Server provides the backend (i.e. the core services, APIs, and REST endpoints) for Jupyter web applications like Jupyter Notebook. Prior to version 1.17.1, if notebook server is started with a value of `root_dir` that contains the starting user's home directory, then the underlying REST API can be used to leak the access token assigned at start time by guessing/brute forcing the PID of the jupyter server. While this requires an authenticated user session, this URL can be used from a cross-site scripting payload or from a hooked or otherwise compromised browser to leak this access token to a malicious third party. This token can be used along with the REST API to interact with Jupyter services/notebooks such as modifying or overwriting critical files, such as .bashrc or .ssh/authorized_keys, allowing a malicious user to read potentially sensitive data and possibly gain control of the impacted system. This issue is patched in version 1.17.1.","aliases":["GHSA-q874-g24w-4q9g","PYSEC-2022-211"],"modified":"2026-04-10T04:47:10.460742Z","published":"2022-06-14T20:40:15Z","related":["CGA-gf67-gpm9-94qq","openSUSE-SU-2024:12147-1","openSUSE-SU-2025:14845-1"],"database_specific":{"cwe_ids":["CWE-200"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/29xxx/CVE-2022-29241.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/29xxx/CVE-2022-29241.json"},{"type":"ADVISORY","url":"https://github.com/jupyter-server/jupyter_server/security/advisories/GHSA-q874-g24w-4q9g"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-29241"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/jupyter-server/jupyter_server","events":[{"introduced":"0"},{"fixed":"e741350461bfeb6f52ccb879cc27d8dca2ef9f8d"}]}],"versions":["0.0.1","0.0.2","0.0.3","0.0.4","0.0.5","0.1.0","0.1.1","0.2.0","0.3.0","1.0.0","1.0.0rc1","1.0.0rc10","1.0.0rc11","1.0.0rc12","1.0.0rc13","1.0.0rc14","1.0.0rc15","1.0.0rc16","1.0.0rc2","1.0.0rc3","1.0.0rc4","1.0.0rc5","1.0.0rc6","1.0.0rc7","1.0.0rc8","1.0.0rc9","1.0.1","1.0.2","1.0.3","1.0.4","1.0.5","1.1.0","1.1.1","1.1.2","1.1.3","1.1.4","1.2.0","1.2.1","1.2.2","1.2.3","1.3.0","1.4.0","1.4.1","1.5.0","1.5.1","1.6.0","1.6.1","v1.10.0","v1.10.1","v1.10.2","v1.11.0","v1.11.1","v1.11.2","v1.12.0","v1.12.1","v1.13.0","v1.13.1","v1.13.2","v1.13.3","v1.13.4","v1.13.5","v1.15.0","v1.15.1","v1.15.2","v1.15.3","v1.15.4","v1.15.5","v1.15.6","v1.16.0","v1.17.0","v1.6.2","v1.6.3","v1.6.4","v1.7.0","v1.7.0a0","v1.7.0a1","v1.7.0a2","v1.8.0","v1.9.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-29241.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H"}]}
