In versions 2.17.0 and earlier, the secret used to sign authentication cookies is persisted to a static file at ~/.local/share/jupyter/runtime/jupyter_cookie_secret and is never rotated when a user changes their password. After a password reset and server restart, any previously issued authentication cookie remains cryptographically valid because the signing key has not changed. An attacker who has captured a session cookie through any means retains full authenticated access to the server regardless of subsequent password changes. This affects deployments using password-based authentication, particularly shared or public-facing servers where credential rotation is expected to revoke existing sessions.

In versions 2.17.0 and earlier, a path traversal vulnerability in the REST API allows an authenticated user to escape the configured root_dir and access sibling directories whose names begin with the same prefix as the root_dir. For example, with a root_dir named \"test\", the API permits access to a sibling directory named \"testtest\" through a crafted request to the /api/contents endpoint using encoded path components. An attacker can read, write, and delete files in affected sibling directories. Multi-tenant deployments using predictable naming schemes are particularly at risk, as a user with a directory named \"user1\" could access directories for user10 through user19 and beyond. A user who can choose a single-character folder name could gain access to a significant number of sibling directories. \n\nVersion 2.18.0 contains a fix. As a workaround, ensure folder names do not share a common prefix with any sibling directory.","references":[{"reference_url":"https://github.com/jupyter-server/jupyter_server/security/advisories/GHSA-5789-5fc7-67v3","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"}],"url":"https://github.com/jupyter-server/jupyter_server/security/advisories/GHSA-5789-5fc7-67v3"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/50018?format=json","purl":"pkg:pypi/jupyter-server@2.18.0","is_vulnerable":false,"affected_by_vulnerabilities":[],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/jupyter-server@2.18.0"}],"aliases":["CVE-2026-35397","GHSA-5789-5fc7-67v3","PYSEC-2026-68"],"risk_score":null,"exploitability":null,"weighted_severity":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-bnpq-rekd-ekdc"}],"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/packages/pkg:pypi/jupyter-server@2.18.0"}
