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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N","score":6.5},"cwes":["CWE-23","CWE-200"],"references":["https://github.com/jupyterlab/jupyterlab/commit/19bd9b96cb2e77170a67e43121637d0b5619e8c6","https://github.com/jupyterlab/jupyterlab/security/advisories/GHSA-44cc-43rp-5947","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/UQJKNRDRFMKGVRIYNNN6CKMNJDNYWO2H/","https://github.com/jupyterlab/jupyterlab/commit/19bd9b96cb2e77170a67e43121637d0b5619e8c6","https://github.com/jupyterlab/jupyterlab/security/advisories/GHSA-44cc-43rp-5947"],"products":["fedoraproject:fedora","jupyter:jupyterlab","jupyter:notebook"],"source":"nvd","synced_at":"2026-10-19T21:44:57.175229480+00:00"},"epss":{"cve":"CVE-2024-22421","score":0.0067,"percentile":0.52003,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-44cc-43rp-5947","url":"https://osv.dev/vulnerability/GHSA-44cc-43rp-5947","summary":"JupyterLab vulnerable to potential authentication and CSRF tokens leak","modified":"2026-09-10T03:50:04.786005565Z","packages":[{"ecosystem":"PyPI","name":"jupyterlab","purl":"pkg:pypi/jupyterlab","ranges":[">=4.0.0 <4.0.11"],"fixed":["4.0.11"]},{"ecosystem":"PyPI","name":"jupyterlab","purl":"pkg:pypi/jupyterlab","ranges":["<3.6.7"],"fixed":["3.6.7"]},{"ecosystem":"PyPI","name":"notebook","purl":"pkg:pypi/notebook","ranges":[">=7.0.0 <7.0.7"],"fixed":["7.0.7"]}]},{"id":"PYSEC-2026-1706","url":"https://osv.dev/vulnerability/PYSEC-2026-1706","summary":"JupyterLab vulnerable to potential authentication and CSRF tokens leak","modified":"2026-07-13T16:42:58.393120611Z","packages":[{"ecosystem":"PyPI","name":"notebook","purl":"pkg:pypi/notebook","ranges":[">=7.0.0 <7.0.7"],"fixed":["7.0.7"]}]},{"id":"PYSEC-2026-2534","url":"https://osv.dev/vulnerability/PYSEC-2026-2534","summary":"JupyterLab vulnerable to potential authentication and CSRF tokens leak","modified":"2026-07-13T16:42:58.393120611Z","packages":[{"ecosystem":"PyPI","name":"jupyterlab","purl":"pkg:pypi/jupyterlab","ranges":["<3.6.7",">=4.0.0 <4.0.11"],"fixed":["3.6.7","4.0.11"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
