Apache Syncope Patches SQL Injection and Privilege Escalation Flaws

The Apache Syncope project has patched two security flaws in its identity management platform. Both Apache Syncope vulnerabilities carry an “important” severity rating. One allows SQL injection, while the other enables a privilege escalation flaw that can turn a regular user into an administrator.

TL;DR

Apache Syncope fixed CVE-2026-57308 and CVE-2026-62183 in versions 4.0.7 and 4.1.2. The first is an SQL injection bug. The second lets some self-service users grant themselves admin roles. No public exploitation has been confirmed.

Why it matters

Syncope manages digital identities across enterprise environments. As a result, a flaw here can affect access to many connected systems. The privilege escalation flaw is the sharper risk, since it can hand out administrator entitlements. The SQL injection bug, meanwhile, needs an already-privileged admin account.

How the attacks work

CVE-2026-57308: SQL injection

This bug lives in the Audit Events search. An administrator with the right entitlements can run arbitrary SQL through stacked queries. The root cause is unsanitized sort parameters. Because it requires admin entitlements, the attacker must already hold significant access.

CVE-2026-62183: privilege escalation

This issue affects user self-service workflows. It applies when the all-Java workflow adapter is used, or a Flowable BPMN definition skips admin approval for self-registration or self-update. In that setup, a REST API call can let a user grant themselves defined roles. Consequently, they gain the entitlements tied to those roles and act as an administrator.

Affected versions

Both flaws share the same affected ranges. They cover Apache Syncope 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.

Patch and mitigation steps

Upgrade without delay. The project recommends moving to version 4.0.7 or 4.1.2, which fix both issues. You can grab the latest builds from the official Apache Syncope downloads page.

Review your workflow configuration as well. Check whether self-registration or self-update paths skip admin approval. For full advisory detail on these Apache Syncope vulnerabilities, see the Apache Syncope security advisories. In short, patch first, then tighten your self-service rules.
