Description

Apache Syncope contains an improper isolation vulnerability that allows an administrator with sufficient entitlements to achieve remote code execution via the connector subsystem. This occurs because scripted connectors (REST and SQL) can run Groovy scripts without adequate sandboxing. The issue affects multiple versions of Apache Syncope prior to 4.0.7 and 4.1.2, which include fixes that harden the Groovy security sandbox.

Technical Analysis

CVE-2026-53421 is an improper isolation or compartmentalization vulnerability in Apache Syncope's connector subsystem. Administrators with appropriate entitlements can exploit the capability of scripted connectors to run Groovy scripts, leading to remote code execution. The vulnerability affects 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. The issue is resolved in versions 4.0.7 and 4.1.2 by enhancing the security sandbox for Groovy scripts.

Potential Impact

An attacker with administrative privileges can execute arbitrary code remotely through the connector subsystem by leveraging scripted connectors that run Groovy scripts. This could lead to full compromise of the affected system. There are no known exploits in the wild at this time.

Mitigation Recommendations

Users should upgrade Apache Syncope to version 4.0.7 or 4.1.2, which include fixes that harden the Groovy security sandbox and mitigate this vulnerability. No other mitigation steps are specified.
