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.","cvssScore":9.8,"cvssSeverity":"CRITICAL","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-78","CWE-917"],"vendors":[],"products":[],"references":[{"url":"https://codeant.ai/security-research/camunda-adhoc-query-expression-rce-cve-2026-109432","tags":[]},{"url":"https://docs.camunda.org/enterprise/download/","tags":[]},{"url":"https://www.vulncheck.com/advisories/camunda-expression-injection-via-orqueries-rce","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
