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-2026-123855/ (Markdown: https://insights.sbomify.com/CVE-2026-123855/index.md)","id":"CVE-2026-123855","markdown":"https://insights.sbomify.com/CVE-2026-123855/index.md","name":"CVE-2026-123855","record":{"aliases":["GHSA-7r7r-mmv3-x6mw"],"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:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-78","name":"Improper Neutralization of Special Elements used in an OS Command"}],"description":"In JetBrains Toolbox App before 3.6.1 command injection was possible via enterprise configuration URLs","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 Toolbox App before 3.6.1 command injection was possible via enterprise configuration URLs","id":"CVE-2026-123855","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 Toolbox App before 3.6.1 nTLM hash disclosure was possible via SVG tool icons from a Remote Development server","id":"CVE-2026-123856"},"nickname":null,"packages":[],"prev":{"headline":"In JetBrains PyCharm before 2026.3 code execution was possible in Safe Mode via a crafted Jupyter notebook widget module","id":"CVE-2026-123854"},"products":["Toolbox App"],"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":"2026-11-07","vendors":["JetBrains"]},"summary":null,"url":"https://insights.sbomify.com/CVE-2026-123855/"}
