CVE-2026-53405: CWE-653 Improper Isolation or Compartmentalization in Apache Software Foundation Apache Syncope
Apache Syncope 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 contain an improper isolation vulnerability. An administrator with sufficient privileges can import BPMN process definitions containing Groovy scriptTasks via the REST API, which execute without sandboxing on the server. This allows arbitrary Groovy code execution with high impact on confidentiality, integrity, and availability. Versions 4.0.7 and 4.1.2 address this issue by sandboxing Groovy scriptTasks.
AI Analysis
Technical Summary
CVE-2026-53405 describes an improper isolation or compartmentalization vulnerability (CWE-653) in Apache Syncope. Administrators can import BPMN process definitions through the REST API that include Groovy scriptTasks. These scripts execute directly on the server without sandboxing, enabling arbitrary code execution. The vulnerability 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 fixed in versions 4.0.7 and 4.1.2 by introducing a security sandbox around Flowable's Groovy scriptTasks to prevent untrusted code execution.
Potential Impact
Successful exploitation allows an administrator-level user to execute arbitrary Groovy scripts on the server hosting Apache Syncope. This can lead to full compromise of confidentiality, integrity, and availability of the system. The CVSS score of 9.8 reflects the critical severity and the potential for complete system takeover.
Mitigation Recommendations
Users should upgrade Apache Syncope to versions 4.0.7 or 4.1.2 or later, which implement sandboxing for Groovy scriptTasks and mitigate this vulnerability. No other official remediation or temporary fixes are documented. Patch status is confirmed by the vendor advisory recommending these versions.
