It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2026-33825 in the wild since at least 22 Apr 2026, including in ransomware campaigns.\n\nAffected product: Microsoft Defender Antimalware Platform. 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-2026-33825/ (Markdown: https://insights.sbomify.com/CVE-2026-33825/index.md)","id":"CVE-2026-33825","markdown":"https://insights.sbomify.com/CVE-2026-33825/index.md","name":"CVE-2026-33825","record":{"aliases":["GHSA-8vp7-4rmv-4868"],"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 authorized local attacker can elevate privileges due to insufficient access control granularity in Microsoft Defender.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"defender_antimalware_platform","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:P/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-1220","name":"Insufficient Granularity of Access Control"}],"description":"Insufficient granularity of access control in Microsoft Defender allows an authorized attacker to elevate privileges locally.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2026-04-17","github_poc":7,"max_poc_stars":10,"metasploit":0,"nuclei":0,"refs":[{"date":"2026-04-17T20:52:08Z","kind":"github_poc","ref":"https://github.com/Letlaka/redsun-bluehammer-undefend-detection-pack","stars":10,"title":"Microsoft Defender XDR KQL detections for RedSun, BlueHammer, UnDefend, and CVE-2026-33825-related Defender abuse behaviors."},{"date":"2026-05-18T16:28:47Z","kind":"github_poc","ref":"https://github.com/0xredash/CVE-2026-33825","stars":9,"title":"CVE-2026-33825"},{"date":"2026-05-02T06:52:02Z","kind":"github_poc","ref":"https://github.com/Joe1sn/CVE-2026-33825","stars":4,"title":"RedSun PoC for self use"},{"date":"2026-04-20T09:38:06Z","kind":"github_poc","ref":"https://github.com/Bilal3755/Detecting_blue_hammer_vuln","stars":0,"title":"Threat hunting query for bluehammer CVE windows CVE-2026-33825"},{"date":"2026-04-22T12:29:39Z","kind":"github_poc","ref":"https://github.com/kaleth4/CVE-2026-33825","stars":0,"title":null},{"date":"2026-10-01T08:37:42Z","kind":"github_poc","ref":"https://github.com/anasabugaddara-ux/defender-bluehammer-audit","stars":0,"title":"Defensive Metasploit post module for CVE-2026-33825 (BlueHammer): Defender version/posture detection + compromise-hunt.
