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.\n\n## Affected\n\n- `7 >= 7.24.0 < 7.24.14`\n- `7 >= 7.23.0 < 7.23.17`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"abyssal","depthScore":66,"depthScoreParts":{"impact":53.9,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":225063,"id":"CVE-2026-109432","ts":1792431329136,"field":"exploit_available","old":"false","new":"true"}]}
