CVE-2026-53421: 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 can achieve remote code execution through the connector subsystem by relying on scripted connectors' (REST and SQL) capability to run Groovy scripts. 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 hardening the Groovy security sandbox.
AI Analysis
Technical Summary
CVE-2026-53421 is an improper isolation or compartmentalization vulnerability (CWE-653) in Apache Syncope's connector subsystem. Administrators with appropriate entitlements can leverage the ability of scripted connectors (REST and SQL) to run Groovy scripts to achieve remote 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 vendor recommends upgrading to versions 4.0.7 or 4.1.2, which implement a hardened Groovy security sandbox to mitigate this issue.
Potential Impact
An attacker with administrative privileges can execute arbitrary code remotely through the connector subsystem by exploiting the Groovy scripting capability. This can lead to full compromise of the affected Apache Syncope instance. There are no known exploits in the wild at this time.
Mitigation Recommendations
Users should upgrade affected Apache Syncope installations to version 4.0.7 or 4.1.2, which include fixes that harden the Groovy security sandbox and prevent this vulnerability. No other mitigations or temporary workarounds are indicated.
