It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-86504 in the wild and no public exploit code.\n\nAffected product: JetBrains IntelliJ IDEA. 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-2026-86504/ (Markdown: https://insights.sbomify.com/CVE-2026-86504/index.md)","id":"CVE-2026-86504","markdown":"https://insights.sbomify.com/CVE-2026-86504/index.md","name":"CVE-2026-86504","record":{"aliases":["GHSA-h5xf-2v4c-pv86"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"IntelliJ IDEA IDE","requires_auth":"none","summary":"Attackers can execute host-level code by bypassing project-trust confirmation during Dev Container builds in IntelliJ IDEA.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"JetBrains","cpe":[],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-829","name":"Inclusion of Functionality from Untrusted Control Sphere"}],"description":"In JetBrains IntelliJ IDEA before 2026.2.2 missing project-trust confirmation before building a Dev Container allowed host-level code execution","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":"Code injection in IntelliJ IDEA","id":"CVE-2026-86504","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Information disclosure in IntelliJ IDEA","id":"CVE-2026-86505"},"packages":[],"prev":{"headline":"Server-side request forgery in IntelliJ IDEA","id":"CVE-2026-86503"},"products":["IntelliJ IDEA"],"published":"2026-09-07","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":"2026-09-09","vendors":["JetBrains"]},"summary":"Attackers can execute host-level code by bypassing project-trust confirmation during Dev Container builds in IntelliJ IDEA.","url":"https://insights.sbomify.com/CVE-2026-86504/"}
