An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-69843 in the wild and no public exploit code.\n\nAffected product: Microsoft Fabric. 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-2026-69843/ (Markdown: https://insights.sbomify.com/CVE-2026-69843/index.md)","id":"CVE-2026-69843","markdown":"https://insights.sbomify.com/CVE-2026-69843/index.md","name":"CVE-2026-69843","record":{"aliases":["GHSA-v78g-wqrm-wm64"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Fabric","requires_auth":"none","summary":"An attacker can bypass authentication via spoofing to elevate privileges in Microsoft Fabric, requiring immediate patching.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"fabric","vendor":"microsoft"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-290","name":"Authentication Bypass by Spoofing"}],"description":"Authentication bypass by spoofing in Microsoft Fabric allows an unauthorized attacker to elevate privileges over a network.","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 Fabric Elevation of Privilege Vulnerability","id":"CVE-2026-69843","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"auth_bypass","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Windows Win32k Elevation of Privilege Vulnerability","id":"CVE-2026-69844"},"packages":[],"prev":{"headline":"Windows Encrypting File System (EFS) Elevation of Privilege Vulnerability","id":"CVE-2026-69841"},"products":["Microsoft Fabric"],"published":"2026-09-17","related":[{"cvss_score":9.9,"headline":"Microsoft Fabric Elevation of Privilege Vulnerability","id":"CVE-2026-63509","kev_date_added":null,"published":"2026-08-20"},{"cvss_score":8.5,"headline":"Microsoft Fabric Elevation of Privilege Vulnerability","id":"CVE-2026-70178","kev_date_added":null,"published":"2026-09-03"}],"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-14","vendors":["Microsoft"]},"summary":"An attacker can bypass authentication via spoofing to elevate privileges in Microsoft Fabric, requiring immediate patching.","url":"https://insights.sbomify.com/CVE-2026-69843/"}
