An authenticated attacker with specific business privileges could submit specially crafted input, which is interpreted as executable ABAP code by the rule processing logic. Successful exploitation could allow the attacker to execute ABAP arbitrary code into the system, resulting in full compromise of the affected system and high impact on confidentiality, integrity, and availability of the system.","state":0,"publishedAt":"2026-10-13T00:23:52.51+00:00","modifiedAt":"2026-10-14T03:58:55.884+00:00","affected":[{"ecosystem":"Vendor product","name":"SAP S/4HANA (Manage Substitution/Validation Rules)","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"SAP_SE\",\n                    \"product\": \"SAP S/4HANA (Manage Substitution/Validation Rules)\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"S4CORE 105\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"106\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"107\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"108\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"109\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H","score":9.9,"severity":"CRITICAL"}],"references":["https://me.sap.com/notes/3805589","https://url.sap/sapsecuritypatchday"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-89107","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-89107","identifiers":["CVE-2026-89107"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
