CVE-2026-56287: Apache Fineract: Boolean SQL Injection in Client Search API (orderBy parameter) leading to Local File Disclosure

• Severity: high (CVSS 8.1 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.7% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-07-15 · updated 2026-10-24
• Weakness: CWE-89

Description

A boolean-based SQL Injection vulnerability exists in Apache Fineract's Client Search API (GET /api/v1/clients) in versions up to and including 1.14.0. The orderBy and sortOrder request parameters are concatenated into a SQL query without sufficient validation, allowing an authenticated user with permission to view clients to inject arbitrary SQL via a crafted orderBy value. This can be leveraged to perform blind boolean-based data extraction and, on MySQL/MariaDB, to disclose arbitrary files readable by the database process via the LOAD_FILE() function. Users are recommended to upgrade to a version containing the fix

Affected products

• Apache Software Foundation Apache Fineract: before 1.15.0 — fixed in 1.15.0

How to fix
