CVE-2026-42797: CWE-202 Exposure of Sensitive Information Through Data Queries in Apache Software Foundation Apache Syncope
Exposure of Sensitive Information Through Data Queries vulnerability in Apache Syncope. An administrator with adequate entitlements for Derived Schemas can create a malicious JEXL expression which allows any administrator with sufficient entitlements for User read to access User-related security-sensitive information. This issue affects Apache Syncope: 3.0 through 3.0.16, 4.0 through 4.0.5, 4.1.0. Users are recommended to upgrade to version 4.0.6 / 4.1.1, which fix this issue by further restricting the JEXL expression definition.
AI Analysis
Technical Summary
This vulnerability involves exposure of sensitive information through data queries in Apache Syncope. Specifically, an administrator authorized to manage Derived Schemas can craft a malicious JEXL expression. This expression can then be leveraged by any administrator with User read permissions to access sensitive user-related security information. The flaw affects multiple versions of Apache Syncope prior to 4.0.6 and 4.1.1. The vendor fixed the issue by imposing stricter restrictions on JEXL expression definitions in the updated versions.
Potential Impact
The vulnerability allows unauthorized access to sensitive user-related security information by administrators who otherwise have only read permissions on User data, potentially leading to exposure of confidential information. There are no known exploits in the wild at this time.
Mitigation Recommendations
Users should upgrade Apache Syncope to version 4.0.6 or 4.1.1, where the vulnerability is fixed by further restricting JEXL expression definitions. No other mitigation or temporary workaround is indicated in the available data.
