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: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-86320 exists.\n\nAffected product: Red Hat Enterprise Linux 10. 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-2026-86320/ (Markdown: https://insights.sbomify.com/CVE-2026-86320/index.md)","id":"CVE-2026-86320","markdown":"https://insights.sbomify.com/CVE-2026-86320/index.md","name":"CVE-2026-86320","record":{"aliases":["ALSA-2026:80495","ALSA-2026:80496","ALSA-2026:80973","CLSA-2026-1792771054","DEBIAN-CVE-2026-86320","GHSA-rvpr-5p35-6vf8","MGASA-2026-0519","OESA-2026-4074","OESA-2026-4224","OESA-2026-4225","OESA-2026-4226","RHSA-2026:80495","RHSA-2026:80496","RHSA-2026:80973","RHSA-2026:84832","RHSA-2026:84833","RHSA-2026:84834","RHSA-2026:84842","RLSA-2026:80495","RLSA-2026:80496","RLSA-2026:80973","UBUNTU-CVE-2026-86320","openSUSE-SU-2026:11845-1"],"analysis":{"component_type":"developer_tool","fix_type":"patch","impacts":["code_execution"],"network_reachable":"adjacent_or_local","non_default_config":true,"product_category":"Flatpak build tool","requires_auth":"none","summary":"Attackers can execute arbitrary code on the host by providing malicious Git hooks in patch sources when use-git-am is enabled.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","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-94","name":"Improper Control of Generation of Code"}],"description":"A flaw was found in flatpak-builder where Git hooks are not disabled when applying patch sources with use-git-am: true.
