What Should I Do?

Patch Immediately

This vulnerability is confirmed under active exploitation (CISA KEV). Patch within 24-48 hours if possible.

Summary

### Impact Programs using jt-jiffle, and allowing Jiffle script to be provided via network request, are susceptible to a Remote Code Execution as the Jiffle script is compiled into Java code via Janino, and executed. In particular, this affects the downstream GeoServer project. ### Patches Version 1.2.22 will contain a patch that disables the ability to inject malicious code into the resulting script. ### Workarounds Negate the ability to compile Jiffle scripts from the final application, by removing janino-x.y.z.jar from the classpath. ### References None.
