{"id":"ALPINE-CVE-2023-40170","details":"jupyter-server is the backend for Jupyter web applications. Improper cross-site credential checks on `/files/` URLs could allow exposure of certain file contents, or accessing files when opening untrusted files via  \"Open image in new tab\". This issue has been addressed in commit `87a49272728` which has been included in release `2.7.2`. Users are advised to upgrade. Users unable to upgrade may use the lower performance `--ContentsManager.files_handler_class=jupyter_server.files.handlers.FilesHandler`, which implements the correct checks.","modified":"2026-10-27T08:33:30.676792239Z","published":"2023-08-28T21:15:07.873Z","upstream":["CVE-2023-40170"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-40170"}],"affected":[{"package":{"name":"jupyter-server","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/jupyter-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2023-40170.json"}},{"package":{"name":"jupyter-server","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/jupyter-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2023-40170.json"}},{"package":{"name":"jupyter-server","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/jupyter-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2023-40170.json"}},{"package":{"name":"jupyter-server","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/jupyter-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2023-40170.json"}},{"package":{"name":"jupyter-server","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/jupyter-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2023-40170.json"}},{"package":{"name":"jupyter-server","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/jupyter-server?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.3-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2023-40170.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
