Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-27679 in the wild and no public exploit code.\n\nAffected product: SAP_SE SAP S/4HANA Frontend OData Service (Manage Reference Structures). 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-2026-27679/ (Markdown: https://insights.sbomify.com/CVE-2026-27679/index.md)","id":"CVE-2026-27679","markdown":"https://insights.sbomify.com/CVE-2026-27679/index.md","name":"CVE-2026-27679","record":{"aliases":["GHSA-fcjm-cm6x-4v66"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"SAP S/4HANA OData Service","requires_auth":"low_privilege","summary":"Attackers can update and delete reference structure entities without authorization, compromising data integrity in SAP S/4HANA.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"sap","cpe":[{"product":"manage_reference_structures","vendor":"sap"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"Due to missing authorization checks in the SAP S/4HANA frontend OData Service (Manage Reference Structures), an attacker could update and delete child entities via exposed OData services without proper authorization.
