Users of JupyterLab who click on a malicious link may get their `Authorization` and `XSRFToken` tokens exposed to a third party when running an older `jupyter-server` version. JupyterLab versions 4.1.0b2, 4.0.11, and 3.6.7 are patched. No workaround has been identified, however users should ensure to upgrade `jupyter-server` to version 2.7.2 or newer which includes a redirect vulnerability fix.","dates":{"published":"2024-01-19T21:15:00.000Z","modified":"2026-02-04T03:17:54.692Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":6.5,"severity":"medium","version":"3.1","versionLabel":"v3.1","source":"OSV · Ubuntu","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","computed":true,"selection":"version-preference"},"metrics":[{"version":"3.1","versionLabel":"v3.1","source":"OSV · Ubuntu","score":6.5,"severity":"medium","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","exploitability":7.2,"impact":6,"computed":true}]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"ubuntu","product":"jupyter-notebook","name":"jupyter-notebook","label":"jupyter-notebook","ecosystem":"Ubuntu","cpePart":null,"purl":"pkg:deb/ubuntu/jupyter-notebook","purlType":"deb","versions":[{"text":"All versions","noFixRecorded":true,"fixedIn":null}],"versionsText":"All versions (No fix recorded)","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://ubuntu.com/security/CVE-2024-22421","label":"ubuntu.com/security/CVE-2024-22421","hostname":"ubuntu.com","tags":["REPORT"]},{"url":"https://github.com/jupyterlab/jupyterlab/security/advisories/GHSA-44cc-43rp-5947","label":"github.com/jupyterlab/jupyterlab/security/advisories/GHSA-44cc-43rp-5947","hostname":"github.com","tags":["REPORT"]},{"url":"https://github.com/jupyterlab/jupyterlab/commit/19bd9b96cb2e77170a67e43121637d0b5619e8c6","label":"github.com/jupyterlab/jupyterlab/commit/19bd9b96cb2e77170a67e43121637d0b5619e8c6","hostname":"github.com","tags":["REPORT"]},{"url":"https://www.cve.org/CVERecord?id=CVE-2024-22421","label":"www.cve.org/CVERecord?id=CVE-2024-22421","hostname":"www.cve.org","tags":["REPORT"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":["CVE-2024-22421"]},"timeline":[{"kind":"published","date":"2024-01-19T21:15:00.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-02-04T03:17:54.692Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":26,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-21T16:37:24.829Z","stale":false,"partial":false}}
