Summary
Kiteworks Email Protection Gateway before version 9.5.0 is vulnerable to Unsafe Reflection and does not sufficiently restrict the code that the mail-processing pipeline could load from an imported rule configuration. An authenticated administrator with mail-rule configuration privileges could cause the gateway to load and execute code beyond the approved set of mail-processing components, potentially in the context of the mail-gateway service account.
