Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-42898 in the wild and no public exploit code.\n\nAffected product: Microsoft Dynamics 365. 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-2026-42898/ (Markdown: https://insights.sbomify.com/CVE-2026-42898/index.md)","id":"CVE-2026-42898","markdown":"https://insights.sbomify.com/CVE-2026-42898/index.md","name":"CVE-2026-42898","record":{"aliases":["GHSA-f8w6-8hpv-rrjj"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Dynamics 365 on-premises","requires_auth":"low_privilege","summary":"An authorized attacker can execute arbitrary code remotely in Microsoft Dynamics 365 on-premises due to improper code generation control.","user_interaction":"not_required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"dynamics_365","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:H/E:U/RL:O/RC:C","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Improper control of generation of code ('code injection') in Microsoft Dynamics 365 (on-premises) allows an authorized attacker to execute code 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 Dynamics 365 On-Premises Remote Code Execution Vulnerability","id":"CVE-2026-42898","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:dynamics_365","products":["microsoft:dynamics_365"],"type":"code_injection","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"ASP.NET Core Denial of Service Vulnerability","id":"CVE-2026-42899"},"packages":[],"prev":{"headline":"Microsoft Exchange Server Cross-Site Scripting","id":"CVE-2026-42897"},"products":["Microsoft Dynamics 365 (on-premises) version 9.1"],"published":"2026-05-12","related":[{"cvss_score":9.9,"headline":"Dynamics 365 Elevation of Privilege Vulnerability","id":"CVE-2026-47647","kev_date_added":null,"published":"2026-06-18"},{"cvss_score":9.3,"headline":"Microsoft Dynamics 365 (online) Spoofing Vulnerability","id":"CVE-2026-32210","kev_date_added":null,"published":"2026-04-23"},{"cvss_score":9.1,"headline":"Microsoft Dynamics 365 On-Premises Remote Code Execution Vulnerability","id":"CVE-2026-42833","kev_date_added":null,"published":"2026-05-12"},{"cvss_score":9,"headline":"Microsoft Dynamics 365 Elevation of Privilege Vulnerability","id":"CVE-2024-38182","kev_date_added":null,"published":"2024-07-31"},{"cvss_score":8.8,"headline":"Microsoft Dynamics 365 On-Premises Remote Code Execution Vulnerability","id":"CVE-2026-65772","kev_date_added":null,"published":"2026-09-08"},{"cvss_score":8.8,"headline":"Microsoft Dynamics 365 On-Premises Remote Code Execution Vulnerability","id":"CVE-2026-77908","kev_date_added":null,"published":"2026-09-08"}],"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":"2026-08-10","vendors":["Microsoft"]},"summary":"An authorized attacker can execute arbitrary code remotely in Microsoft Dynamics 365 on-premises due to improper code generation control.","url":"https://insights.sbomify.com/CVE-2026-42898/"}
