Improper Privilege Management in Apache Syncope

Publication date: 2026-07-20

Last updated on: 2026-07-20

Assigner: Apache Software Foundation

Description
Improper Privilege Management vulnerability in Apache Syncope. When: * the all-Java user workflow adapter is configured, or * the Flowable user workflow adapter is configured, bearing a BPMN definition not requiring admin approval for user self registration of self update requests the following scenario could happen. A REST API call can allow the user to grant themselves one or more of defined Roles, thus gaining their Entitlements and becoming in fact an administrator; the actual Entitlements gained depend on the Roles that are effectively defined on the specific Syncope deployment. 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.

Executive Summary

This is an Improper Privilege Management vulnerability in Apache Syncope. It allows a user to grant themselves admin roles via a REST API call when specific workflow adapters are configured without requiring admin approval for self-registration or updates.

Detection Guidance

Check Apache Syncope configuration files for the all-Java or Flowable user workflow adapters with BPMN definitions allowing self-registration or self-update without admin approval. Review REST API logs for unauthorized role assignment attempts.

Impact Analysis

An attacker could exploit this to escalate their privileges to administrator level, gaining access to sensitive functions and data depending on the roles defined in the system.

Compliance Impact

This vulnerability allows unauthorized users to grant themselves administrative privileges, potentially leading to unauthorized access to sensitive data. This could violate compliance requirements under GDPR (data protection) and HIPAA (healthcare data privacy) by enabling unauthorized access to personal or protected health information.

Mitigation Strategies

Upgrade Apache Syncope to version 4.0.7 or 4.1.2 or later. If upgrading is not immediately possible, disable the affected workflow adapters or modify BPMN definitions to require admin approval for role changes.
