CVE-2026-7602Public exploitNetwork attack vector

Authenticated code execution via unsafe rule reflection

Published May 2, 2026 · Updated May 2, 2026

Remote code execution in JeecgBoot 3.9.0 through 3.9.1 allows remote authenticated users to execute commands through fill-rule edits. The /sys/fillRule/edit handler stores an unchecked ruleClass value, and FillRuleUtil.executeRule later passes it to Class.forName().newInstance(). A standard account can poison an existing rule, but execution occurs only after department creation triggers that rule and a usable classpath gadget is present.
