CVE-2026-57821 Apache CVE debrief

Who should care

Defenders should care about this vulnerability as it can be used to perform time-based blind SQL injection for data exfiltration and denial of service for other users. Roles that should assess exposure include security teams, system administrators, and developers. Deployment contexts that should assess exposure include Apache Fineract versions up to and including 1.14.0.

Why it matters

This SQL Injection vulnerability in Apache Fineract's Office Search API can be used for data exfiltration and denial of service. Defenders should assess exposure, upgrade to a fixed version, and implement input validation and sanitization to prevent exploitation.

• Data exfiltration through time-based blind SQL injection
• Denial of service for other users due to database connection pool exhaustion
• Potential for lateral movement and privilege escalation
• Need for input validation and sanitization to prevent exploitation

Technical summary

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 can be leveraged to perform time-based blind SQL injection for data exfiltration. The vulnerability affects Apache Fineract versions up to and including 1.14.0 and can be mitigated by upgrading to a version containing the fix and implementing input validation and sanitization. The vulnerability has a CVSS score of 8.1 and is classified as HIGH severity.

Defensive priority

Upgrade to a version containing the fix, assess exposure, and verify inventory

Recommended defensive actions

• Upgrade to a version containing the fix
• Assess exposure and verify inventory
• Implement input validation and sanitization
• Monitor for suspicious activity
• Review compensating controls for exposed systems
• Track exceptions and retest remediated assets
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
