An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-96276 in the wild and no public exploit code.\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-2026-96276/ (Markdown: https://insights.sbomify.com/CVE-2026-96276/index.md)","id":"CVE-2026-96276","markdown":"https://insights.sbomify.com/CVE-2026-96276/index.md","name":"CVE-2026-96276","record":{"aliases":["DEBIAN-CVE-2026-96276","UBUNTU-CVE-2026-96276"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"Flatpak build tool","requires_auth":"none","summary":"A malicious SDK can write arbitrary files to the host system during flatpak build-init, potentially leading to code execution or privilege escalation.","user_interaction":"required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"If a malicious SDK container declares an extension point with a crafted `directory` path, and a developer runs `flatpak build-init --writable-sdk --sdk-extension` with that SDK, attacker-chosen files could be written outside the working directory, since the target path is resolved via a function that allows `..` traversal.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Flatpak: flatpak: arbitrary write in host context via flatpak build-init","id":"CVE-2026-96276","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"path_traversal","year":"2026"},"n_packages":0,"n_references":3,"next":{"headline":"Apache Thrift: Ruby `SimpleServer` ends `serve()` on any non-Transport/Protocol exception","id":"CVE-2026-96277"},"packages":[],"prev":{"headline":"Flatpak: flatpak: arbitrary write access as root via extra-data extraction","id":"CVE-2026-96275"},"products":["Red Hat Enterprise Linux 10","Red Hat Enterprise Linux 7","Red Hat Enterprise Linux 8","Red Hat Enterprise Linux 9"],"published":"2026-09-23","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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-27","vendors":["Red Hat"]},"summary":"A malicious SDK can write arbitrary files to the host system during flatpak build-init, potentially leading to code execution or privilege escalation.","url":"https://insights.sbomify.com/CVE-2026-96276/"}
