No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-123290/ (Markdown: https://insights.sbomify.com/CVE-2026-123290/index.md)","id":"CVE-2026-123290","markdown":"https://insights.sbomify.com/CVE-2026-123290/index.md","name":"CVE-2026-123290","record":{"aliases":["GHSA-6fp9-33ch-6835"],"analysis":null,"analysis_generated_by":null,"assigner":"JetBrains","cpe":[{"name":"JetBrains Datalore","product":"datalore","vendor":"jetbrains"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-201","name":"Insertion of Sensitive Information Into Sent Data"}],"description":"In JetBrains Datalore before 2026.4 hidden notebook code was exposed to unauthenticated users via the public interactive report content endpoint","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"In JetBrains Datalore before 2026.4 hidden notebook code was exposed to unauthenticated users via the public interactive report content endp","id":"CVE-2026-123290","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":null,"year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"In JetBrains Datalore before 2026.4 improper owner validation allowed reading another workspace's issues and runs notebook","id":"CVE-2026-123291"},"nickname":null,"packages":[],"prev":{"headline":"In JetBrains Datalore before 2026.4 improper authorisation allowed notebook viewers to modify files","id":"CVE-2026-123289"},"products":["Datalore"],"published":"2026-11-06","related":[{"cvss_score":8.8,"headline":"In JetBrains Datalore before 2026.4 workspace collaborators could obtain the owner's SSH private key via Git backup","id":"CVE-2026-123836","kev_date_added":null,"published":"2026-11-06"},{"cvss_score":7.5,"headline":"In JetBrains Datalore before 2026.4 improper scope validation in database tasks allowed using another workspace's service account","id":"CVE-2026-123834","kev_date_added":null,"published":"2026-11-06"},{"cvss_score":6.3,"headline":"In JetBrains Datalore before 2026.3 command execution was possible in the database task container via JVM options injection","id":"CVE-2026-123285","kev_date_added":null,"published":"2026-11-06"},{"cvss_score":6.3,"headline":"In JetBrains Datalore before 2026.1 session hijacking was possible due to missing secure attribute for cookie settings","id":"CVE-2026-32745","kev_date_added":null,"published":"2026-03-13"},{"cvss_score":5.9,"headline":"In JetBrains Datalore before 2026.4 improper authorisation allowed read the notebook owner's file storage session token","id":"CVE-2026-123286","kev_date_added":null,"published":"2026-11-06"},{"cvss_score":5.9,"headline":"In JetBrains Datalore before 2026.4 private notebook files could be downloaded without authentication via published interactive reports","id":"CVE-2026-123287","kev_date_added":null,"published":"2026-11-06"},{"cvss_score":5.9,"headline":"In JetBrains Datalore before 2026.4 code execution was possible in another user's computation via an init script upload race condition","id":"CVE-2026-123835","kev_date_added":null,"published":"2026-11-06"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-11-06","vendors":["JetBrains"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-123290/"}
