Summary
by MITRE • 11/02/2026
Improper neutralization of special elements used in an SQL command ('SQL injection') vulnerability in Apache Syncope.
This CVE covers an incomplete fix for CVE-2026-77051: an administrator with adequate entitlements can achieve execution of arbitrary SQL via stacked queries, leveraging unsanitized opEvent parameters. Reference: https://cve.org/CVERecord?id=CVE-2026-77051
This issue affects Apache Syncope: from 3.0.0-M0 through 3.0.16, from 4.0.0-M0 through 4.0.8, from 4.1.0-M0 through 4.1.3.
Users are recommended to upgrade to version 4.0.9 / 4.1.4, which fix this issue.

The vulnerability identified as CVE-2026-77051 represents a critical security flaw within the Apache Syncope identity and access management platform, specifically categorized under CWE-89 Improper Neutralization of Special Elements used in an SQL Command commonly known as SQL injection. This issue stems from an incomplete remediation effort regarding how the application processes input parameters associated with operational events. Although previous patches attempted to address similar issues, they failed to fully sanitize specific inputs related to opEvent parameters, leaving a pathway for attackers to inject malicious SQL code into backend database queries executed by the server.
The technical root cause lies in the insufficient validation and escaping of user-supplied data before it is incorporated into dynamic SQL statements. When an authenticated administrator with sufficient privileges interacts with the system's event handling mechanisms, the unsanitized opEvent parameters are directly concatenated or improperly bound within SQL commands. This allows a malicious actor to manipulate the structure of these queries by injecting additional SQL syntax, such as stacked queries that can execute multiple distinct database operations in a single request sequence. The vulnerability is particularly severe because it requires administrative-level access, which implies that an attacker must first compromise valid credentials for a high-privilege account or exploit another vector to gain such access before leveraging this flaw.
The operational impact of this SQL injection vulnerability is significant, as successful exploitation can lead to the execution of arbitrary commands on the underlying database server. This capability enables attackers to perform unauthorized data exfiltration, modify critical identity records, alter authentication configurations, or potentially achieve remote code execution depending on the specific capabilities and configuration of the database management system in use. The ability to execute stacked queries amplifies the risk by allowing multiple actions to be chained together, such as reading sensitive tables followed by dropping essential schema objects, thereby causing denial of service or complete compromise of the identity infrastructure managed by Apache Syncope.
This vulnerability affects specific versions of Apache Syncope including releases from 3.0.0-M0 through 3.0.16 and from 4.0.0-M0 through 4.0.8, as well as the 4.1.x branch up to version 4.1.3. The flaw is mapped to ATT&CK technique T1190 Exploit Public-Facing Application when considering initial access via compromised admin credentials and T1059 Command and Scripting Interpreter if the database allows for OS-level command execution through stored procedures or extended commands. Organizations running these affected versions are strongly advised to upgrade immediately to version 4.0.9 or 4.1.4, which contain the necessary code changes to properly sanitize opEvent parameters and prevent SQL injection attacks. Until an upgrade is performed, administrators should implement strict network-level access controls to limit exposure of Syncope interfaces and monitor database logs for anomalous query patterns indicative of exploitation attempts.
