CVE-2026-71288Network attack vector

Authenticated SQL injection via unsafe report ordering

Published Aug 5, 2026 · Updated Aug 5, 2026

SQL injection in Koha 26.05.01-1 and earlier allows remote authenticated users to read sensitive database data via crafted report ordering. The guided report builder concatenates order_by and dynamically named {order}_ovalue parameters into an ORDER BY clause without validation or an allowlist. The create_reports or execute_reports permission is sufficient, enabling time-based extraction of patron PII and credential material.
