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-2026-80098 in the wild and no public exploit code.\n\nAffected product: Microsoft Copilot Studio. 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-2026-80098/ (Markdown: https://insights.sbomify.com/CVE-2026-80098/index.md)","id":"CVE-2026-80098","markdown":"https://insights.sbomify.com/CVE-2026-80098/index.md","name":"CVE-2026-80098","record":{"aliases":["GHSA-r9hf-26xj-x88v"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Copilot Studio","requires_auth":"none","summary":"An attacker can elevate privileges in Microsoft Copilot Studio due to improper cryptographic signature verification.","user_interaction":"not_required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"copilot_studio","vendor":"microsoft"}],"cvss":{"score":9.3,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:H/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-347","name":"Improper Verification of Cryptographic Signature"}],"description":"Improper verification of cryptographic signature in Copilot Studio 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 Studio Elevation of Privilege Vulnerability","id":"CVE-2026-80098","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":"Auth bypass in WP Module Data","id":"CVE-2026-80099"},"packages":[],"prev":{"headline":"Microsoft Authenticator Elevation of Privilege Vulnerability","id":"CVE-2026-80097"},"products":["Microsoft Copilot Studio"],"published":"2026-09-03","related":[{"cvss_score":9.3,"headline":"Microsoft Copilot Studio Elevation Of Privilege Vulnerability","id":"CVE-2024-49038","kev_date_added":null,"published":"2024-11-26"},{"cvss_score":8.5,"headline":"Microsoft Copilot Studio Information Disclosure Vulnerability","id":"CVE-2024-38206","kev_date_added":null,"published":"2024-08-06"},{"cvss_score":7.5,"headline":"Copilot Studio Information Disclosure Vulnerability","id":"CVE-2026-21520","kev_date_added":null,"published":"2026-01-22"},{"cvss_score":7.4,"headline":"Copilot Studio Information Disclosure Vulnerability","id":"CVE-2024-43610","kev_date_added":null,"published":"2024-10-09"}],"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 elevate privileges in Microsoft Copilot Studio due to improper cryptographic signature verification.","url":"https://insights.sbomify.com/CVE-2026-80098/"}
