Publication date: 2026-11-02

Last updated on: 2026-11-02

Assigner: Apache Software Foundation

Description
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.

CWE ID Description
CWE-89 The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.

Executive Summary

This is a SQL injection vulnerability in Apache Syncope where an administrator with proper permissions can execute arbitrary SQL commands through unsanitized opEvent parameters. The incomplete fix for a previous CVE (CVE-2026-77051) allows stacked queries to bypass security measures.

Impact Analysis

An attacker with administrator access could manipulate database queries to steal, modify, or delete sensitive data. This could lead to unauthorized access to user information, system compromise, or data breaches depending on the database contents.

Compliance Impact

This vulnerability could lead to unauthorized data access or exposure, violating GDPR's data protection requirements and HIPAA's safeguards for protected health information. Non-compliance may result in legal penalties, fines, or reputational damage.

Mitigation Strategies

Upgrade Apache Syncope to version 4.0.9 or 4.1.4 or later to address the SQL injection vulnerability.
