CVE-2026-56287 Apache CVE debrief

Who should care

Defenders of Apache Fineract instances, security teams, and administrators of systems using Apache Fineract should assess exposure and verify inventory. They should also review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. Additionally, they should plan vendor-supported updates or mitigations through normal change control where exposure is confirmed and review compensating controls for exposed and

Why it matters

CVE-2026-56287 is a high-severity SQL Injection vulnerability in Apache Fineract's Client Search API. An authenticated user can inject arbitrary SQL, potentially leading to data extraction and file disclosure. Defenders should assess exposure, verify inventory, and upgrade to a patched version.

• Potential data extraction via blind boolean-based SQL injection
• Potential disclosure of arbitrary files readable by the database process on MySQL/MariaDB
• Verification of inventory and exposure of Apache Fineract instances
• Upgrade to a patched version to prevent exploitation

Technical summary

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. 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.

Defensive priority

Upgrade to a patched version, assess exposure, and verify inventory.

Recommended defensive actions

• Upgrade to a version of Apache Fineract containing the fix
• Assess exposure and verify inventory of Apache Fineract instances
• Restrict access to the Client Search API to authorized users
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and NVD entry provide details on the boolean-based SQL Injection vulnerability in Apache Fineract's Client Search API. The vulnerability allows an authenticated user to inject arbitrary SQL and potentially disclose arbitrary files readable by the database process.
