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-2026-54130 in the wild and no public exploit code.\n\nAffected product: Microsoft 365 Copilot. 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-2026-54130/ (Markdown: https://insights.sbomify.com/CVE-2026-54130/index.md)","id":"CVE-2026-54130","markdown":"https://insights.sbomify.com/CVE-2026-54130/index.md","name":"CVE-2026-54130","record":{"aliases":["GHSA-9cqp-hgpj-49wr"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft 365 Copilot","requires_auth":"none","summary":"An unauthorized attacker can disclose information over the network due to missing authentication in Microsoft 365 Copilot.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"365_copilot","vendor":"microsoft"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-306","name":"Missing Authentication for Critical Functionality"}],"description":"Missing authentication for critical function in M365 Copilot allows an unauthorized attacker to disclose information 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":"M365 Copilot Information Disclosure Vulnerability","id":"CVE-2026-54130","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:365_copilot","products":["microsoft:365_copilot"],"type":"missing_authorization","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Excel Remote Code Execution Vulnerability","id":"CVE-2026-54131"},"packages":[],"prev":{"headline":"Windows Hyper-V Elevation of Privilege Vulnerability","id":"CVE-2026-54129"},"products":["Microsoft 365 Copilot"],"published":"2026-06-18","related":[{"cvss_score":9.9,"headline":"Microsoft 365 Copilot Elevation of Privilege Vulnerability","id":"CVE-2026-85885","kev_date_added":null,"published":"2026-09-17"},{"cvss_score":9.9,"headline":"Microsoft M365 Copilot Remote Code Execution Vulnerability","id":"CVE-2026-50517","kev_date_added":null,"published":"2026-07-24"},{"cvss_score":9.8,"headline":"GDI+ Remote Code Execution Vulnerability","id":"CVE-2025-60724","kev_date_added":null,"published":"2025-11-11"},{"cvss_score":9.8,"headline":"GDI+ Remote Code Execution Vulnerability","id":"CVE-2025-53766","kev_date_added":null,"published":"2025-08-12"},{"cvss_score":9.6,"headline":"Microsoft Edge Copilot Remote Code Execution Vulnerability","id":"CVE-2026-48561","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":9.6,"headline":"Microsoft Office app Remote Code Execution Vulnerability","id":"CVE-2021-43905","kev_date_added":null,"published":"2021-12-15"}],"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":"2026-09-24","vendors":["Microsoft"]},"summary":"An unauthorized attacker can disclose information over the network due to missing authentication in Microsoft 365 Copilot.","url":"https://insights.sbomify.com/CVE-2026-54130/"}
