Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-26137 in the wild and no public exploit code.\n\nAffected product: Microsoft Exchange Online. 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-2026-26137/ (Markdown: https://insights.sbomify.com/CVE-2026-26137/index.md)","id":"CVE-2026-26137","markdown":"https://insights.sbomify.com/CVE-2026-26137/index.md","name":"CVE-2026-26137","record":{"aliases":["GHSA-88qf-p934-h9qg"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Microsoft Exchange Online","requires_auth":"low_privilege","summary":"An authorized attacker can exploit Server-Side Request Forgery in Microsoft Exchange Online to elevate privileges over the network.","user_interaction":"not_required","vuln_class":"ssrf"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"365_copilot_chat","vendor":"microsoft"}],"cvss":{"score":9.9,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:L/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-918","name":"Server-Side Request Forgery"}],"description":"Server-side request forgery (ssrf) in Microsoft Exchange allows an authorized 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":"Microsoft Exchange Elevation of Privilege Vulnerability","id":"CVE-2026-26137","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"ssrf","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Microsoft Purview Elevation of Privilege Vulnerability","id":"CVE-2026-26138"},"packages":[],"prev":{"headline":"Microsoft Copilot Information Disclosure Vulnerability","id":"CVE-2026-26136"},"products":["Microsoft Exchange Online"],"published":"2026-03-19","related":[{"cvss_score":9.3,"headline":"Copilot Information Disclosure Vulnerability","id":"CVE-2025-59272","kev_date_added":null,"published":"2025-10-09"},{"cvss_score":9.3,"headline":"Copilot Information Disclosure Vulnerability","id":"CVE-2025-59286","kev_date_added":null,"published":"2025-10-09"},{"cvss_score":8.6,"headline":"Microsoft 365 Copilot Business Chat Information Disclosure Vulnerability","id":"CVE-2026-78501","kev_date_added":null,"published":"2026-09-17"},{"cvss_score":8.2,"headline":"Microsoft 365 Copilot BizChat Information Disclosure Vulnerability","id":"CVE-2025-53787","kev_date_added":null,"published":"2025-08-07"},{"cvss_score":7.5,"headline":"M365 Copilot Information Disclosure Vulnerability","id":"CVE-2026-26129","kev_date_added":null,"published":"2026-05-07"},{"cvss_score":7.5,"headline":"M365 Copilot Information Disclosure Vulnerability","id":"CVE-2026-26164","kev_date_added":null,"published":"2026-05-07"}],"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":"2026-06-19","vendors":["Microsoft"]},"summary":"An authorized attacker can exploit Server-Side Request Forgery in Microsoft Exchange Online to elevate privileges over the network.","url":"https://insights.sbomify.com/CVE-2026-26137/"}
