CVE-2025-57738Network attack vectorHinoki check available

Authenticated code execution via unsandboxed Groovy implementations

Published Oct 20, 2025 · Updated Oct 20, 2025

Improper isolation in Apache Syncope affected releases allows remote authenticated users to execute code on the Core server. ImplementationManager compiles and loads administrator-supplied Groovy interface implementations without restricting their access to JVM capabilities. The attacker must hold delegated administrative rights to upload implementations; execution then inherits the Core process's access.
