CVE-2026-63071: CWE-653 Improper Isolation or Compartmentalization in Apache Software Foundation Apache Syncope
Improper Isolation or Compartmentalization vulnerability in Apache Syncope. An administrator with adequate entitlements for Implementations can create a malicious Groovy class containing untrusted code bypassing the Groovy security 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 tightening the Groovy security sandbox.
AI Analysis
Technical Summary
CVE-2026-63071 describes a CWE-653 improper isolation or compartmentalization vulnerability in Apache Syncope. Administrators with sufficient privileges to manage Implementations can introduce malicious Groovy code that escapes the intended Groovy security sandbox protections. This flaw affects multiple milestone and stable releases of Apache Syncope, specifically 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 vulnerability is addressed by enhancements to the Groovy sandbox implemented in Apache Syncope versions 4.0.7 and 4.1.2.
Potential Impact
An attacker with administrator-level entitlements related to Implementations can execute untrusted Groovy code beyond the sandbox restrictions, potentially leading to unauthorized code execution or privilege escalation within the Apache Syncope environment. This compromises the isolation guarantees expected from the Groovy sandbox.
Mitigation Recommendations
Users should upgrade affected Apache Syncope installations to version 4.0.7 or 4.1.2, where the Groovy security sandbox has been tightened to prevent this bypass. No other mitigation or temporary workaround is indicated. Patch status is confirmed by the vendor advisory recommending these versions.
