Apache Syncope 1.0.0 before 1.0.9 and 1.1.0 before 1.1.7 allows remote administrators to execute arbitrary Java code via vectors related to Apache Commons JEXL expressions, "derived schema definition," "user / role templates," and "account links of resource mappings."

An administrator with user search entitlements in Apache Syncope 1.2.x before 1.2.11 and 2.0.x before 2.0.8 can recover sensitive security values using the fiql and orderby parameters.

Apache Syncope 1.1.x before 1.1.8 uses weak random values to generate passwords, which makes it easier for remote attackers to guess the password via a brute force attack.
