{"id":"PYSEC-2026-1478","summary":"Unsecured endpoints in the jupyter-lsp server extension","details":"### Impact\nInstallations of jupyter-lsp running in environments without configured file system access control (on the operating system level), and with jupyter-server instances exposed to non-trusted network are vulnerable to unauthorised access and modification of file system beyond the jupyter root directory.\n\n### Patches\nVersion 2.2.2 has been patched.\n\n### Workarounds\nUsers of jupyterlab who do not use jupyterlab-lsp can uninstall jupyter-lsp.\n\n### Credits\nWe would like to credit Bary Levy, researcher of pillar.security research team, for the discovery and responsible disclosure of this vulnerability.\n\nEdit: based on advice from pillar.security the Confidentiality/Integrity/Availability were increased to High to reflect potential for critical impact on publicly hosted jupyter-server instances lacking isolation of user privileges on operating system level (for best practices please consult https://jupyterhub.readthedocs.io/en/stable/explanation/websecurity.html#protect-users-from-each-other) and CWE-94 was added due to a potential vulnerability chaining in specific environments.","aliases":["CVE-2024-22415","GHSA-4qhp-652w-c22x"],"modified":"2026-07-07T17:46:13.871473697Z","published":"2026-07-07T11:45:30.723739Z","references":[{"type":"WEB","url":"https://github.com/jupyter-lsp/jupyterlab-lsp/security/advisories/GHSA-4qhp-652w-c22x"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-22415"},{"type":"FIX","url":"https://github.com/jupyter-lsp/jupyterlab-lsp/commit/4ad12f204ad0b85580fc32137c647baaff044e95"},{"type":"PACKAGE","url":"https://github.com/jupyter-lsp/jupyterlab-lsp"},{"type":"WEB","url":"https://github.com/jupyter-lsp/jupyterlab-lsp/releases/tag/v5.0.2"},{"type":"PACKAGE","url":"https://pypi.org/project/jupyter-lsp"},{"type":"ADVISORY","url":"https://github.com/advisories/GHSA-4qhp-652w-c22x"}],"affected":[{"package":{"name":"jupyter-lsp","ecosystem":"PyPI","purl":"pkg:pypi/jupyter-lsp"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.2.2"}]}],"versions":["0.6.0b0","0.7.0","0.7.0b0","0.8.0","0.9.0","0.9.1","0.9.2","0.9.3","1.0.0","1.0.0rc0","1.1.0","1.1.1","1.1.2","1.1.3","1.1.4","1.2.0","1.3.0","1.4.0","1.4.1","1.5.0","1.5.1","2.0.0","2.0.1","2.1.0","2.2.0","2.2.1"],"database_specific":{"source":"https://github.com/pypa/advisory-database/blob/main/vulns/jupyter-lsp/PYSEC-2026-1478.yaml"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L"}]}
