Summary

JeecgBoot v3.9.2 is vulnerable to Remote command execution. The CodeNode component of the AI Flow module supports Groovy script execution. While the `SecurityCheck` class employs a blacklist mechanism to intercept dangerous calls, the dynamic nature of Groovy allows this blacklist to be completely bypassed through string concatenation and reflection.
