SQL Injection in Apache (CVE-2026-56287)
Summary
SQL injection in Apache (CVE-2026-56287). Confidential information can be exposed externally. Exploitable via GET /api/v1/clients.
Original description
The description as published by the source.
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

CVE-2026-56287 (Apache) — CWE-89 / CVSS v3 8.1
Attack vector: remote (network-reachable) / no user interaction
Attack surface: GET /api/v1/clients
Plan: 1) Audit SBOM/dependencies, 2) Stage→prod upgrade, 3) Add WAF/proxy monitoring on affected endpoints, 4) Hunt IOCs in logs.
Refs: see the GHSA / vendor advisory / patched release linked on this page.
SQL injection (CWE-89) exists in Apache. Attackers reach the vulnerable code path via GET /api/v1/clients.
Check the vendor advisory for the affected versions of Apache. Attack surface: GET /api/v1/clients.
Severity: High (CVSS 8.1/10). Confidential information can be exposed externally.
Update to the patched release per vendor advisory.
Until the patch is applied: disable the affected feature, apply WAF rules, or restrict access via network ACLs.
Search webserver/proxy logs for unusual GET /api/v1/clients requests with malformed payloads or SQL meta-characters. Run grep -r 'Apache' . against your dependency files (package-lock.json, requirements.txt, go.sum) to find affected services.
Response actions
Concrete steps and command examples for SOC/SRE teams to execute in order
-
1Identify exposure identify
grep -r 'Apache' . | grep -v node_modulesリポジトリと本番環境の依存ファイル (package-lock.json / requirements.txt / go.sum / Gemfile.lock 等) で
Apacheを grep し、稼働しているサービス・バージョンを把握する。 -
2Hunt for indicators of compromise detect
grep 'GET /api/v1/clients' /var/log/nginx/access.log | grep -E '(unusual_payload|sqli_pattern)'アクセスログで
GET /api/v1/clientsへの異常なリクエスト (不正な認証ヘッダ・SQLメタ文字)を過去 30〜90日分捜索。WAF/SIEM があれば該当パスのアラート発火履歴を確認。 -
3Post-deployment verification verify
Replay attack against GET /api/v1/clients on staging to confirm patch closes the vectorパッチ適用後、ステージングで PoC または同等の悪用パターンを再現して脆弱性が閉じたことを確認。本番では Step 2 と同じログクエリでアラート再発が無いか継続監視。
