It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-50656 exists.\n\nAffected product: Microsoft Malware Protection Engine. 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-2026-50656/ (Markdown: https://insights.sbomify.com/CVE-2026-50656/index.md)","id":"CVE-2026-50656","markdown":"https://insights.sbomify.com/CVE-2026-50656/index.md","name":"CVE-2026-50656","record":{"aliases":["GHSA-hgx9-224c-3p2x"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Microsoft Defender","requires_auth":"low_privilege","summary":"An attacker can exploit a flaw in the Microsoft Malware Protection Engine to gain elevated privileges on the system.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"malware_protection_engine","vendor":"microsoft"}],"cvss":{"score":7.8,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H/E:F/RL:U/RC:C","version":"3.1"},"cwes":[{"id":"CWE-59","name":"Improper Link Resolution Before File Access"}],"description":"Microsoft is aware of an elevation of privilege in the Microsoft Malware Protection Engine in Microsoft Defender publicly referred to as \u0026quot;RoguePlanet \u0026quot;.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-06-10","github_poc":4,"max_poc_stars":10,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-06-18T13:16:36Z","kind":"github_poc","ref":"https://github.com/0xredash/CVE-2026-50656","stars":10,"title":"CVE-2026-50656"},{"date":"2026-06-10T21:31:47Z","kind":"github_poc","ref":"https://github.com/g0thamRabb1t/CVE-2026-50656-rogueplanet-validation","stars":2,"title":"Validation report for the RoguePlanet Microsoft Defender PoC in a controlled Windows 11 lab environment, including build notes, Defender detection results, risk assessment, and mitigation recommendations."},{"date":"2026-08-16T09:11:25Z","kind":"github_poc","ref":"https://github.com/eh-amish/Windows-Defender-Security-Auditor-CVE-2026-50656-","stars":1,"title":null},{"date":"2026-08-12T07:36:26Z","kind":"github_poc","ref":"https://github.com/HORKimhab/CVE-2026-50656","stars":0,"title":"CVE-2026-50656, CVE-2026-69414"}],"tier":"weaponised"},"has_fix":null,"headline":"Microsoft Defender Elevation of Privilege Vulnerability","id":"CVE-2026-50656","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"privilege_escalation","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Defender for Endpoint for Mac Information Disclosure Vulnerability","id":"CVE-2026-50657"},"packages":[],"prev":{"headline":"Microsoft Windows Media Foundation Remote Code Execution Vulnerability","id":"CVE-2026-50655"},"products":["Microsoft Malware Protection Engine"],"published":"2026-06-16","related":[{"cvss_score":7.8,"headline":"Microsoft Defender Link Following","id":"CVE-2026-41091","kev_date_added":"2026-05-20","published":"2026-05-20"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2013-1346","kev_date_added":null,"published":"2013-05-15"},{"cvss_score":8.1,"headline":"Microsoft Defender Remote Code Execution Vulnerability","id":"CVE-2026-45584","kev_date_added":null,"published":"2026-05-20"},{"cvss_score":7.8,"headline":"Microsoft Defender Elevation of Privilege Vulnerability","id":"CVE-2026-69414","kev_date_added":null,"published":"2026-08-14"},{"cvss_score":7.8,"headline":"Microsoft Defender Remote Code Execution Vulnerability","id":"CVE-2026-55011","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":7.8,"headline":"Microsoft Defender Remote Code Execution Vulnerability","id":"CVE-2026-55012","kev_date_added":null,"published":"2026-07-14"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-09-24","vendors":["Microsoft"]},"summary":"An attacker can exploit a flaw in the Microsoft Malware Protection Engine to gain elevated privileges on the system.","url":"https://insights.sbomify.com/CVE-2026-50656/"}
