Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-85887 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-2026-85887/ (Markdown: https://insights.sbomify.com/CVE-2026-85887/index.md)","id":"CVE-2026-85887","markdown":"https://insights.sbomify.com/CVE-2026-85887/index.md","name":"CVE-2026-85887","record":{"aliases":["GHSA-g3r4-5f4w-4vh4"],"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":"low_privilege","summary":"An authorized attacker can disclose sensitive information due to incorrect permission assignments in Microsoft 365 Copilot.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"365_copilot","vendor":"microsoft"}],"cvss":{"score":7.7,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"Incorrect permission assignment for critical resource in M365 Copilot allows an authorized 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-2026-85887","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:365_copilot","products":["microsoft:365_copilot"],"type":"information_disclosure","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft SQL Server Information Disclosure Vulnerability","id":"CVE-2026-85888"},"packages":[],"prev":{"headline":"Microsoft SQL Server Remote Code Execution Vulnerability","id":"CVE-2026-85886"},"products":["Microsoft 365 Copilot"],"published":"2026-09-17","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":"M365 Copilot Information Disclosure Vulnerability","id":"CVE-2026-54130","kev_date_added":null,"published":"2026-06-18"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-10-14","vendors":["Microsoft"]},"summary":"An authorized attacker can disclose sensitive information due to incorrect permission assignments in Microsoft 365 Copilot.","url":"https://insights.sbomify.com/CVE-2026-85887/"}
