CVE-2026-57821: Apache Fineract: Office list: SQL Injection via Subquery in orderBy

[Terence Monteiro <terencemo () apache org>]

Severity: important 

Affected versions:

- Apache Fineract through 1.14.0
- Apache Fineract 1.15.0 unaffected

Description:

A SQL Injection vulnerability exists in Apache Fineract's Office Search API (GET /api/v1/offices) in versions up to and 
including 1.14.0. The orderBy request parameter is concatenated into a SQL query without sufficient validation, 
allowing an authenticated user with permission to view offices to inject arbitrary SQL via a crafted orderBy value. 
This is a bypass of the ColumnValidator fix introduced for CVE-2024-32838, which does not detect bare subqueries in the 
ORDER BY position. This can be leveraged to perform time-based blind SQL injection for data exfiltration. Because the 
injected query blocks the database connection for its full duration, concurrent exploitation can exhaust the 
application's database connection pool, resulting in denial of service for other users. Users are recommended to 
upgrade to a version containing the fix.
