Apache · Apache Syncope · CVE-2026-53405
**Name of the Vulnerable Software and Affected Versions**
Apache Syncope versions 3.0.0-M0 through 3.0.16
Apache Syncope versions 4.0.0-M0 through 4.0.6
Apache Syncope versions 4.1.0-M0 through 4.1.1
**Description**
An improper isolation issue allows an administrator with sufficient entitlements to import arbitrary BPMN process definitions via the REST API and initiate the process. If the imported BPMN process contains a Groovy `scriptTask`, the script is executed directly on the server without a sandbox, potentially leading to arbitrary code execution.
**Recommendations**
Upgrade versions 3.0.0-M0 through 3.0.16 to version 4.0.7.
Upgrade versions 4.0.0-M0 through 4.0.6 to version 4.0.7.
Upgrade versions 4.1.0-M0 through 4.1.1 to version 4.1.2.
