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-2026-123281/ (Markdown: https://insights.sbomify.com/CVE-2026-123281/index.md)","id":"CVE-2026-123281","markdown":"https://insights.sbomify.com/CVE-2026-123281/index.md","name":"CVE-2026-123281","record":{"aliases":["GHSA-96qf-j59p-cg96"],"analysis":null,"analysis_generated_by":null,"assigner":"JetBrains","cpe":[],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-88","name":"Improper Neutralization of Argument Delimiters in a Command"}],"description":"In JetBrains Datalore before 2026.4 notebook code could execute commands in the sidecar container via the mount broker","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 notebook code could execute commands in the sidecar container via the mount broker","id":"CVE-2026-123281","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 missing expiration validation of account tokens allowed a new authenticated session","id":"CVE-2026-123282"},"nickname":null,"packages":[],"prev":{"headline":"In JetBrains Datalore before 2026.2.4 unauthenticated users could execute code via published interactive reports","id":"CVE-2026-123280"},"products":["Datalore"],"published":"2026-11-06","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-11-10","vendors":["JetBrains"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-123281/"}
