An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-59118 in the wild and no public exploit code.\n\nAffected product: Microsoft Copilot Cowork. 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-2026-59118/ (Markdown: https://insights.sbomify.com/CVE-2026-59118/index.md)","id":"CVE-2026-59118","markdown":"https://insights.sbomify.com/CVE-2026-59118/index.md","name":"CVE-2026-59118","record":{"aliases":["GHSA-jc2g-2frr-2pxq"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Copilot Cowork","requires_auth":"none","summary":"An unauthorized attacker can elevate privileges in Microsoft Copilot Cowork due to improper authorization, requiring a patch.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"power_apps","vendor":"microsoft"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-285","name":"Improper Authorization"}],"description":"Improper authorization in Copilot Cowork 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":"Copilot Cowork Elevation of Privilege Vulnerability","id":"CVE-2026-59118","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":"PowerShell Elevation of Privilege Vulnerability","id":"CVE-2026-59119"},"packages":[],"prev":{"headline":"Windows Terminal Remote Code Execution Vulnerability","id":"CVE-2026-59117"},"products":["Copilot Cowork"],"published":"2026-08-06","related":[{"cvss_score":9.1,"headline":"Microsoft Power Apps Information Disclosure Vulnerability","id":"CVE-2025-47733","kev_date_added":null,"published":"2025-05-08"},{"cvss_score":9,"headline":"Microsoft Power Apps Desktop Client Spoofing Vulnerability","id":"CVE-2026-26149","kev_date_added":null,"published":"2026-04-14"},{"cvss_score":8,"headline":"Microsoft Power Apps Remote Code Execution Vulnerability","id":"CVE-2026-32172","kev_date_added":null,"published":"2026-04-23"},{"cvss_score":8,"headline":"PowerApps Desktop Client Remote Code Execution Vulnerability","id":"CVE-2026-20960","kev_date_added":null,"published":"2026-01-16"},{"cvss_score":5.4,"headline":"Microsoft Power Apps (online) Spoofing Vulnerability","id":"CVE-2023-32052","kev_date_added":null,"published":"2023-07-11"},{"cvss_score":3,"headline":"Microsoft Power Apps Spoofing Vulnerability","id":"CVE-2023-32024","kev_date_added":null,"published":"2023-06-14"}],"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)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-10-28","vendors":["Microsoft"]},"summary":"An unauthorized attacker can elevate privileges in Microsoft Copilot Cowork due to improper authorization, requiring a patch.","url":"https://insights.sbomify.com/CVE-2026-59118/"}
