The EPSS score is not available, but because the flaw requires an attacker to gain write access to the Quartz job table, exploitation is limited to authenticated users with sufficient privileges.

In practice, an attacker able to use the previewSql injection can overwrite job data and trigger the gadget chain via a cron trigger, achieving arbitrary code execution within the container."}}}}, "created": "2026-04-16T22:30:03.067342+00:00", "updated": "2026-04-17T02:30:07.316108+00:00", "vendors": ["dataease", "dataease$PRODUCT$dataease"]}
