What it is
From the CVE record
Improper isolation or compartmentalization vulnerability in Apache Syncope. An administrator with adequate entitlements can import arbitrary BPMN process definitions via the REST API and then start the process. When a BPMN process containing a JUEL expression is imported and started, the expression is executed directly on the server, with no sandbox. This issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 through 4.0.8, from 4.1.0 through 4.1.3. Users are recommended to upgrade to version 4.0.9 / 4.1.4, which fix this issue by rejecting BPMN definitions including expression attributes.
