Overview

CVE-2025-57738 is a high-severity vulnerability. It was published on October 20, 2025 and has a CVSS 3.1 base score of 7.2 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.2, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

Apache Syncope offers the ability to extend / customize the base behavior on every deployment by allowing to provide custom implementations of a few Java interfaces; such implementations can be provided either as Java or Groovy classes, with the latter being particularly attractive as the machinery is set for runtime reload.

Such a feature has been available for a while, but recently it was discovered that a malicious administrator can inject Groovy code that can be executed remotely by a running Apache Syncope Core instance.

Users are recommended to upgrade to version 3.0.14 / 4.0.2, which fix this issue by forcing the Groovy code to run in a sandbox.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
