An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2026-26133 and fix it if it is affected.\n\nWhat it is: CVE-2026-26133 is a high-severity code injection vulnerability in Microsoft 365 Copilot, published on 13 Mar 2026. 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-2026-26133 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-2026-26133/ (Markdown: https://insights.sbomify.com/CVE-2026-26133/index.md)","id":"CVE-2026-26133","markdown":"https://insights.sbomify.com/CVE-2026-26133/index.md","name":"CVE-2026-26133","record":{"aliases":["GHSA-rjf5-cxrf-4rvw"],"analysis":{"component_type":"mobile_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft 365 Copilot","requires_auth":"none","summary":"An AI command injection flaw in Microsoft 365 Copilot allows attackers to disclose sensitive information over the network.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"365_copilot","vendor":"microsoft"},{"product":"edge","vendor":"microsoft"},{"product":"excel","vendor":"microsoft"},{"product":"loop","vendor":"microsoft"},{"product":"onenote","vendor":"microsoft"},{"product":"outlook","vendor":"microsoft"},{"product":"power_bi","vendor":"microsoft"},{"product":"powerpoint","vendor":"microsoft"},{"product":"teams","vendor":"microsoft"},{"product":"word","vendor":"microsoft"}],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-77","name":"Improper Neutralization of Special Elements used in a Command"}],"description":"AI command injection 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-2026-26133","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:365_copilot","products":["microsoft:365_copilot","microsoft:edge","microsoft:excel","microsoft:outlook","microsoft:powerpoint","microsoft:word"],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Office Elevation of Privilege Vulnerability","id":"CVE-2026-26134"},"packages":[],"prev":{"headline":"Windows Kernel Elevation of Privilege Vulnerability","id":"CVE-2026-26132"},"products":["Microsoft 365 Copilot for Android","Microsoft 365 Copilot for iOS","Microsoft Edge for Android","Microsoft Edge for iOS","Microsoft Excel for Android","Microsoft Excel for iOS","Microsoft Loop for iOS","Microsoft OneNote","Microsoft OneNote for Android","Microsoft Outlook for Android","Microsoft Outlook for Mac","Microsoft Outlook for iOS","Microsoft PowerBI for Android","Microsoft PowerBI for iOS","Microsoft PowerPoint for Android","Microsoft PowerPoint for iOS","Microsoft Teams for Android","Microsoft Teams for iOS","Microsoft Word for Android","Microsoft Word for iOS"],"published":"2026-03-13","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":"2026-06-19","vendors":["Microsoft"]},"summary":"An AI command injection flaw in Microsoft 365 Copilot allows attackers to disclose sensitive information over the network.","url":"https://insights.sbomify.com/CVE-2026-26133/"}
