Attackers can supply a malicious JUEL expression such as dueAfterExpression inside an orQueries entry to achieve arbitrary Java reflection and invoke java.lang.Runtime.exec, resulting in operating-system command execution as the engine service user.","state":0,"publishedAt":"2026-10-19T15:08:29.023+00:00","modifiedAt":"2026-10-19T16:34:01.291+00:00","affected":[{"ecosystem":"Vendor product","name":"Camunda 7","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"Camunda\",\n                    \"product\": \"Camunda 7\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"7.24.0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"7.24.14\"\n                        },\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"7.23.0\",\n                            \"versionType\": \"semver\",\n                            \"lessThan\": \"7.23.17\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3,"severity":"CRITICAL"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8,"severity":"CRITICAL"}],"references":["https://codeant.ai/security-research/camunda-adhoc-query-expression-rce-cve-2026-109432","https://docs.camunda.org/enterprise/download/","https://www.vulncheck.com/advisories/camunda-expression-injection-via-orqueries-rce"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-109432","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-109432","identifiers":["CVE-2026-109432"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
