By tricking a user into visiting a malicious subdomain, the attacker can achieve an XSS directly affecting the former's session. More precisely, in the context of JupyterHub, this XSS could achieve full access to JupyterHub API and user's single-user server. The affected configurations are single-origin JupyterHub deployments and JupyterHub deployments with user-controlled applications running on subdomains or peer subdomains of either the Hub or a single-user server. This vulnerability is fixed in 4.1.0.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79","CWE-352","CWE-565"],"references":["https://github.com/jupyterhub/jupyterhub/commit/e2798a088f5ad45340fe79cdf1386198e664f77f","https://github.com/jupyterhub/jupyterhub/security/advisories/GHSA-7r3h-4ph8-w38g","https://github.com/jupyterhub/jupyterhub/commit/e2798a088f5ad45340fe79cdf1386198e664f77f","https://github.com/jupyterhub/jupyterhub/security/advisories/GHSA-7r3h-4ph8-w38g"],"products":["jupyter:jupyterhub"],"source":"nvd","synced_at":"2026-10-19T21:47:51.568503435+00:00"},"epss":{"cve":"CVE-2024-28233","score":0.00329,"percentile":0.26042,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-7r3h-4ph8-w38g","url":"https://osv.dev/vulnerability/GHSA-7r3h-4ph8-w38g","summary":"Cross site scripting (XSS) in JupyterHub via Self-XSS leveraged by Cookie Tossing","modified":"2026-09-10T03:50:00.245591053Z","packages":[{"ecosystem":"PyPI","name":"jupyterhub","purl":"pkg:pypi/jupyterhub","ranges":["<4.1.0"],"fixed":["4.1.0"]}]},{"id":"PYSEC-2026-1480","url":"https://osv.dev/vulnerability/PYSEC-2026-1480","summary":"Cross site scripting (XSS) in JupyterHub via Self-XSS leveraged by Cookie Tossing","modified":"2026-07-07T17:57:03.463828143Z","packages":[{"ecosystem":"PyPI","name":"jupyterhub","purl":"pkg:pypi/jupyterhub","ranges":["<4.1.0"],"fixed":["4.1.0"]}]}],"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).
