SQL injection via uncast deserialized array values
Published Jun 25, 2026 · Updated Jun 25, 2026
SQL injection in managers.php in Cacti 1.2.30 and earlier allows remote authenticated users to execute arbitrary SQL statements. The action handler deserializes selected_graphs_array and concatenates its uncast elements into a DELETE WHERE id IN clause. SNMP agent management permission is required; successful injection can read or alter the application's database and interrupt service.
