When JupyterHub is used with FirstUseAuthenticator, a vulnerability in versions prior to 1.0.0 allows unauthorized access to any user's account if `create_users=True` and the username is known or guessed. One may upgrade to version 1.0.0 or apply a patch manually to mitigate the vulnerability. For those who cannot upgrade, there is no complete workaround, but a partial mitigation exists. One can disable user creation with `c.FirstUseAuthenticator.create_users = False`, which will only allow login with fully normalized usernames for already existing users prior to jupyterhub-firstuserauthenticator 1.0.0. If any users have never logged in with their normalized username (i.e. lowercase), they will still be vulnerable until a patch or upgrade occurs.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/31438"}, {"timestamp": "2021-11-03T00:00:00Z", "date_only": true, "value": "2021-11-03", "kind": "other", "label": "Date", "source": "gsd \u00b7 GSD-2021-41194", "record": "GSD-2021-41194", "field": "namespaces.gitlab.com.advisories.0.date"}, {"timestamp": "2021-11-03T12:26:00Z", "date_only": false, "value": "2021-11-03T12:26Z", "kind": "other", "label": "Last Modified Date", "source": "gsd \u00b7 GSD-2021-41194", "record": "GSD-2021-41194", "field": "namespaces.nvd.nist.gov.lastModifiedDate"}, {"timestamp": "2021-11-03T14:26:52.434Z", "date_only": false, "value": "2021-11-03T14:26:52.434933Z", "kind": "other", "label": "Updated", "source": "pysec \u00b7 PYSEC-2021-384", "record": "PYSEC-2021-384", "field": "modified"}, {"timestamp": "2023-12-13T01:23:27.059Z", "date_only": false, "value": "2023-12-13T01:23:27.059694Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2021-41194", "record": "GSD-2021-41194", "field": "gsd.osvSchema.modified"}, {"timestamp": "2024-08-04T03:08:31.328Z", "date_only": false, "value": "2024-08-04T03:08:31.328Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "CVE-2021-41194", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2024-08-04T03:08:31.328Z", "date_only": false, "value": "2024-08-04T03:08:31.328Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "CVE-2021-41194", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2024-09-24T21:11:48Z", "date_only": false, "value": "2024-09-24T21:11:48Z", "kind": "other", "label": "Updated", "source": "github \u00b7 GHSA-5XVC-VGMP-JGC3", "record": "GHSA-5XVC-VGMP-JGC3", "field": "modified"}, {"timestamp": "2026-06-17T04:08:04.187Z", "date_only": false, "value": "2026-06-17T04:08:04.187", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2021-41194", "record": "FKIE_CVE-2021-41194", "field": "lastModified"}]}
