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-2026-56178 in the wild and no public exploit code.\n\nAffected product: Microsoft Defender for Endpoint for Mac. 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-2026-56178/ (Markdown: https://insights.sbomify.com/CVE-2026-56178/index.md)","id":"CVE-2026-56178","markdown":"https://insights.sbomify.com/CVE-2026-56178/index.md","name":"CVE-2026-56178","record":{"aliases":["GHSA-2q3v-wwm5-c8hw"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Endpoint security software","requires_auth":"low_privilege","summary":"A local attacker can exploit a race condition in Microsoft Defender for Endpoint for Mac to elevate privileges.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"defender_for_endpoint","vendor":"microsoft"}],"cvss":{"score":5.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"Time-of-check time-of-use (toctou) race condition in Microsoft Defender for Endpoint allows an authorized attacker to elevate privileges locally.","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":"Microsoft Defender for Endpoint for Mac Elevation of Privilege Vulnerability","id":"CVE-2026-56178","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Network Address Translation (NAT) Spoofing Vulnerability","id":"CVE-2026-56179"},"packages":[],"prev":{"headline":"Windows Server Elevation of Privilege Vulnerability","id":"CVE-2026-56177"},"products":["Microsoft Defender for Endpoint for Mac"],"published":"2026-07-14","related":[{"cvss_score":8.8,"headline":"Microsoft Defender for Endpoint Linux Extension Remote Code Execution Vulnerability","id":"CVE-2026-21537","kev_date_added":null,"published":"2026-02-10"},{"cvss_score":8.1,"headline":"Microsoft Defender for Endpoint on Android Spoofing Vulnerability","id":"CVE-2024-49057","kev_date_added":null,"published":"2024-12-10"},{"cvss_score":7.8,"headline":"Microsoft Defender for Endpoint Elevation of Privilege Vulnerability","id":"CVE-2025-47161","kev_date_added":null,"published":"2025-05-15"},{"cvss_score":7.8,"headline":"Microsoft Defender for Endpoint Protection Elevation of Privilege Vulnerability","id":"CVE-2024-21315","kev_date_added":null,"published":"2024-02-13"},{"cvss_score":7.8,"headline":"Microsoft Defender for Endpoint for Mac Elevation of Privilege Vulnerability","id":"CVE-2022-35828","kev_date_added":null,"published":"2022-09-13"},{"cvss_score":7,"headline":"Microsoft Defender for Endpoint for Mac Elevation of Privilege Vulnerability","id":"CVE-2026-50658","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":7,"headline":"Microsoft Defender for Linux Denial of Service Vulnerability","id":"CVE-2025-59497","kev_date_added":null,"published":"2025-10-14"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"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":"2026-10-28","vendors":["Microsoft"]},"summary":"A local attacker can exploit a race condition in Microsoft Defender for Endpoint for Mac to elevate privileges.","url":"https://insights.sbomify.com/CVE-2026-56178/"}
