CVE-2026-71571Network attack vectorHinoki check available

Authenticated SQL injection via unescaped numeric filter

Published Aug 14, 2026 · Updated Aug 14, 2026

SQL injection in JoomliC iCagenda 3.0.0 through 4.0.11 allows remote authenticated users to inject SQL through an admin numeric filter. The backend filter uses a user-controlled numeric value in an SQL query without escaping it; public sources do not identify the parameter, file, or function. Exploitation requires a backend account with access to com_icagenda and can compromise data confidentiality, integrity, and availability.
