Apache Syncope has disclosed three important security vulnerabilities that could allow authorized administrators to execute malicious SQL commands, bypass Groovy sandbox protections, and impersonate higher-privileged users. The issues affect several Apache Syncope 3.0, 4.0, and 4.1 releases and have been fixed in versions 4.0.8 and 4.1.3.
Apache Syncope is an open-source identity management and access governance platform used to manage users, groups, roles, authentication, and provisioning across enterprise applications.
Because the platform often accesses sensitive identity data and administrative interfaces, successful exploitation could create serious security risks for affected organizations.
Apache Syncope Vulnerabilities
The first issue, tracked as CVE-2026-82232, is an SQL injection vulnerability in the Task search feature. The vulnerability exists because Apache Syncope does not properly sanitize special SQL elements supplied through the sort parameter.
An administrator with sufficient permissions could exploit the issue by submitting malicious input through an unsanitized sort clause. The flaw supports stacked queries, meaning an attacker may be able to append and execute additional SQL commands beyond the intended query.
Successful exploitation could expose, alter, or delete database information depending on the database account permissions assigned to Syncope.
Attackers could also use the flaw to manipulate task-related records, extract identity data, or change configuration values stored in the backend database.
CVE-2026-82232 affects the syncope-core-persistence-jpa component in Apache Syncope versions 3.0.0-M0 through 3.0.16, versions 4.0.0-M0 through 4.0.7, and versions 4.1.0-M0 through 4.1.2. Security researcher Alon Galili reported the vulnerability.
The second vulnerability, CVE-2026-77147, is a code injection issue involving the Groovy security sandbox. It affects the syncope-core-spring component and could allow a privileged administrator to bypass intended protections designed to restrict unsafe Groovy code.
According to the advisory, an administrator with Implementations entitlements can create a malicious Groovy Command class containing untrusted code in its static CommandArgs implementation.
When CommandArgs is empty, the attacker can escape the Groovy sandbox and execute code outside the expected security boundaries.
This could allow malicious code to run in the context of the Apache Syncope application, potentially giving an attacker access to application data, backend services, credentials, or connected identity systems. Researcher n0mi1k reported the issue.
A third flaw, CVE-2026-73178, could enable JWT access-token takeover. An administrator with adequate entitlements can use the REST interface to retrieve existing access tokens, including their signed JWT bodies. Those tokens may then be reused to make REST requests while impersonating users with greater administrative permissions.
The JWT issue affects the syncope-core-provisioning-java component across the same vulnerable release ranges. It was also discovered by n0mi1k. Organizations should immediately upgrade Apache Syncope deployments to version 4.0.8 or 4.1.3.
Administrators should also review privileged accounts, audit recent REST API activity, rotate potentially exposed tokens, and monitor database logs for suspicious Task search requests or unexpected SQL behavior.
