CVE-2026-63071 Details
Description
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.
A vulnerability allowing remote code execution has been identified in Apache Syncope versions 3.0.0-M0 prior to 3.0.16, 4.0.0-M0 prior to 4.0.6, and 4.1.0-M0 prior to 4.1.1.
