Improper Isolation or Compartmentalization vulnerability in Apache Syncope. (CVE-2026-53405)
Apache Syncope contains an improper isolation vulnerability allowing an administrator with sufficient entitlements to import and start BPMN process definitions via the REST API. Specifically, when a BPMN process includes a Groovy scriptTask, the Groovy script executes directly on the server without sandboxing. This affects versions from 3.0.0-M0 through 3.0.16, 4.0.0-M0 through 4.0.6, and 4.1.0-M0 through 4.1.1. Upgrading to versions 4.0.7 or 4.1.2 mitigates the issue by adding a security sandbox around Groovy scriptTasks.
AI Analysis
Technical Summary
The vulnerability in Apache Syncope (CVE-2026-53405) arises from improper isolation or compartmentalization of Groovy scriptTasks within BPMN processes imported and started via the REST API by administrators. Without sandboxing, Groovy scripts execute directly on the server, potentially allowing unintended code execution. This affects Apache Syncope versions 3.0.0-M0 through 3.0.16, 4.0.0-M0 through 4.0.6, and 4.1.0-M0 through 4.1.1. The issue is resolved in versions 4.0.7 and 4.1.2 by wrapping Flowable's Groovy scriptTasks with a security sandbox to restrict execution context.
Potential Impact
An administrator with appropriate entitlements can execute arbitrary Groovy scripts on the server by importing and starting crafted BPMN processes. This could lead to unauthorized code execution within the server environment due to lack of sandboxing for Groovy scriptTasks. The impact is limited to administrators who can import BPMN processes via the REST API.
Mitigation Recommendations
Upgrade Apache Syncope to version 4.0.7 or 4.1.2 or later, where the vulnerability is fixed by implementing a security sandbox around Groovy scriptTasks. No other mitigations are indicated by the vendor advisory. Patch status is confirmed by the vendor's recommendation to upgrade to these versions.
