{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/35173?format=json","vulnerability_id":"VCID-zn45-t3yy-p7gf","summary":"An issue was discovered in Project Jupyter JupyterHub OAuthenticator 0.6.x before 0.6.2 and 0.7.x before 0.7.3. When using JupyterHub with GitLab group whitelisting for access control, group membership was not checked correctly, allowing members not in the whitelisted groups to create accounts on the Hub. (Users were not allowed to access other users' accounts, but could create their own accounts on the Hub linked to their GitLab account. GitLab authentication not using gitlab_group_whitelist is unaffected. No other Authenticators are affected.)","aliases":[{"alias":"CVE-2018-7206"},{"alias":"GHSA-8x3m-m3x9-54fj"},{"alias":"PYSEC-2018-151"},{"alias":"PYSEC-2018-68"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/10673?format=json","purl":"pkg:pypi/oauthenticator@0.6.2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-f12e-7kyd-cyhg"},{"vulnerability":"VCID-sfqk-pqmp-nkfj"},{"vulnerability":"VCID-zb4n-rxh3-bbd9"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/oauthenticator@0.6.2"},{"url":"http://public2.vulnerablecode.io/api/packages/10674?format=json","purl":"pkg:pypi/oauthenticator@0.7.3","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-f12e-7kyd-cyhg"},{"vulnerability":"VCID-sfqk-pqmp-nkfj"},{"vulnerability":"VCID-zb4n-rxh3-bbd9"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/oauthenticator@0.7.3"}],"affected_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/10668?format=json","purl":"pkg:pypi/oauthenticator@0.6.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-f12e-7kyd-cyhg"},{"vulnerability":"VCID-sfqk-pqmp-nkfj"},{"vulnerability":"VCID-zb4n-rxh3-bbd9"},{"vulnerability":"VCID-zn45-t3yy-p7gf"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/oauthenticator@0.6.0"},{"url":"http://public2.vulnerablecode.io/api/packages/62813?format=json","purl":"pkg:pypi/oauthenticator@0.6","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-zn45-t3yy-p7gf"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/oauthenticator@0.6"},{"url":"http://public2.vulnerablecode.io/api/packages/10669?format=json","purl":"pkg:pypi/oauthenticator@0.6.1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-f12e-7kyd-cyhg"},{"vulnerability":"VCID-sfqk-pqmp-nkfj"},{"vulnerability":"VCID-zb4n-rxh3-bbd9"},{"vulnerability":"VCID-zn45-t3yy-p7gf"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/oauthenticator@0.6.1"},{"url":"http://public2.vulnerablecode.io/api/packages/10670?format=json","purl":"pkg:pypi/oauthenticator@0.7.0","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-f12e-7kyd-cyhg"},{"vulnerability":"VCID-sfqk-pqmp-nkfj"},{"vulnerability":"VCID-zb4n-rxh3-bbd9"},{"vulnerability":"VCID-zn45-t3yy-p7gf"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/oauthenticator@0.7.0"},{"url":"http://public2.vulnerablecode.io/api/packages/62814?format=json","purl":"pkg:pypi/oauthenticator@0.7","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-zn45-t3yy-p7gf"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/oauthenticator@0.7"},{"url":"http://public2.vulnerablecode.io/api/packages/10671?format=json","purl":"pkg:pypi/oauthenticator@0.7.1","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-f12e-7kyd-cyhg"},{"vulnerability":"VCID-sfqk-pqmp-nkfj"},{"vulnerability":"VCID-zb4n-rxh3-bbd9"},{"vulnerability":"VCID-zn45-t3yy-p7gf"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/oauthenticator@0.7.1"},{"url":"http://public2.vulnerablecode.io/api/packages/10672?format=json","purl":"pkg:pypi/oauthenticator@0.7.2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-f12e-7kyd-cyhg"},{"vulnerability":"VCID-sfqk-pqmp-nkfj"},{"vulnerability":"VCID-zb4n-rxh3-bbd9"},{"vulnerability":"VCID-zn45-t3yy-p7gf"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/oauthenticator@0.7.2"}],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2018-7206","reference_id":"","reference_type":"","scores":[{"value":"0.00651","scoring_system":"epss","scoring_elements":"0.71258","published_at":"2026-06-04T12:55:00Z"},{"value":"0.00651","scoring_system":"epss","scoring_elements":"0.71302","published_at":"2026-06-05T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2018-7206"},{"reference_url":"https://blog.jupyter.org/security-fix-for-jupyterhub-gitlab-oauthenticator-7b14571d1f76","reference_id":"","reference_type":"","scores":[{"value":"8.8","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"value":"8.7","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"},{"value":"HIGH","scoring_system":"generic_textual","scoring_elements":""}],"url":"https://blog.jupyter.org/security-fix-for-jupyterhub-gitlab-oauthenticator-7b14571d1f76"},{"reference_url":"https://github.com/advisories/GHSA-8x3m-m3x9-54fj","reference_id":"","reference_type":"","scores":[{"value":"8.8","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"value":"HIGH","scoring_system":"cvssv3.1_qr","scoring_elements":""},{"value":"8.7","scoring_system":"cvssv4","scoring_elements":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"},{"value":"
