CVE-2026-53405 Details
Description
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 Groovy scriptTask is imported and started, the Groovy script 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 4.0.6, from 4.1.0-M0 through 4.1.1. Users are recommended to upgrade to version 4.0.7 / 4.1.2, which fix this issue by wrapping Flowable's Groovy scriptTasks with security sandbox.
A vulnerability allowing remote code execution has been identified in Apache Syncope versions 3.0.0-M0 prior to 3.0.16, 4.0.0-M0 prior to 4.0.6, and 4.1.0-M0 prior to 4.1.1. This issue arises from improper isolation in the handling of BPMN process definitions. An administrator with the necessary entitlements can import arbitrary BPMN processes via the REST API. Once imported, these processes can be started, and if they include a Groovy scriptTask, the script is executed on the server without any sandboxing, posing a significant security risk.
Users are advised to upgrade to Apache Syncope versions 4.0.7 or 4.1.2, which address this vulnerability by adding a security sandbox around Flowable's Groovy scriptTasks.
