CVE-2026-42782: 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 reaching a non-sandboxed execution path via the class static initializer. This issue affects Apache Syncope: 3.0 through 3.0.16, 4.0 through 4.0.5, 4.1.0. Users are recommended to upgrade to version 4.0.6 / 4.1.1, which fix this issue by forcing even the static initializer in Groovy code to run in a sandbox.
AI Analysis
Technical Summary
CVE-2026-42782 is an improper isolation or compartmentalization vulnerability (CWE-653) in Apache Syncope. It arises because an administrator with Implementations entitlements can craft a Groovy class with untrusted code that executes in a non-sandboxed environment through the class static initializer. This flaw affects Apache Syncope versions 3.0 through 3.0.16, 4.0 through 4.0.5, and 4.1.0. The vulnerability is remediated in versions 4.0.6 and 4.1.1 by enforcing sandbox execution even for static initializers in Groovy scripts.
Potential Impact
The vulnerability allows an administrator with appropriate privileges to execute untrusted Groovy code outside of the sandbox, potentially leading to unauthorized actions or compromise within the Apache Syncope environment. There are no known exploits in the wild at this time.
Mitigation Recommendations
Users should upgrade Apache Syncope to version 4.0.6 or 4.1.1, where this vulnerability is fixed by sandboxing the Groovy static initializer. No other mitigation or temporary workaround is indicated. Patch status is confirmed by the vendor advisory recommending these versions.
