It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-110451 in the wild and no public exploit code.\n\nAffected product: NixOS Nix. 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-2026-110451/ (Markdown: https://insights.sbomify.com/CVE-2026-110451/index.md)","id":"CVE-2026-110451","markdown":"https://insights.sbomify.com/CVE-2026-110451/index.md","name":"CVE-2026-110451","record":{"aliases":["GHSA-5h53-jg3j-22gg","UBUNTU-CVE-2026-110451"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Nix package manager","requires_auth":"none","summary":"Attackers can escape the Seatbelt sandbox on macOS due to a mishandled size threshold, bypassing security restrictions in Nix and Lix.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"}],"description":"Nix before 2.35.3 and Lix before 2.95.4 on macOS allow a Seatbelt sandbox escape (for an unconfined build) because a certain size threshold is mishandled.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Security feature bypass in Nix","id":"CVE-2026-110451","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"security_feature_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Privilege escalation in Nix","id":"CVE-2026-110452"},"packages":[],"prev":{"headline":"Privilege escalation in Nix","id":"CVE-2026-110450"},"products":["Nix"],"published":"2026-10-14","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":"partial"},"state":"PUBLISHED","updated":"2026-10-14","vendors":["NixOS"]},"summary":"Attackers can escape the Seatbelt sandbox on macOS due to a mishandled size threshold, bypassing security restrictions in Nix and Lix.","url":"https://insights.sbomify.com/CVE-2026-110451/"}
