These are dated port-query results, not counts of unauthenticated databases, exposed records, or compromised systems. A response shows that a service answered the scanner; it does not establish what access that service allows.
What the three counts measure
The figures come from the article’s description of a ZoomEye query set collected on 22 September 2026. They identify hosts whose specified ports responded to the query, as reported by that article—not verified totals of vulnerable services. They are a snapshot, not current counts.

| Service and queried port | Reported results | What the port represents |
|---|---|---|
| MQTT, 1883 | 1,659 | Commonly used unencrypted MQTT broker port |
| InfluxDB, 8086 | 2,503 | InfluxDB HTTP API |
| ClickHouse, 8123 | 45,150 | ClickHouse HTTP interface |
Source for all three counts and port descriptions: World Programming’s article, “1659 MQTT, 2503 InfluxDB and 45150 ClickHouse Results: The Data Pipeline Layer,” 22 September 2026. The article also reports 15,906 Cassandra results on port 9042 and 1,550 Elasticsearch results on port 9200 for the same query set, but those figures do not change what the three results above establish.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
A port response does not show whether authentication is enabled, whether a particular account can read or alter data, whether the service contains sensitive information, or whether anyone has accessed it improperly. Determining authentication state requires a different check from observing a port response. The source does not establish that any of the responding services accepted anonymous access.
#1 Best Overall
Why the largest count is not the greatest-risk ranking
The three results are not a like-for-like security comparison. They involve different services, interfaces, protocols, and probe responses. The source notes that ClickHouse’s HTTP interface is comparatively straightforward to index, while Cassandra’s binary protocol is less amenable to a lightweight probe. How a service responds can affect what an internet scan finds.
So 45,150 ClickHouse responses do not mean ClickHouse is less secure than MQTT or InfluxDB, nor that all responding hosts expose data. The counts show query results for particular ports in one snapshot; risk depends on the actual configuration, access controls, data, and network path of each installation.
What owners should check on their own systems
Use these checks only for systems and network ranges you own or are authorized to assess. A matching result should prompt investigation by the system owner, not an assumption that the service is vulnerable.
- Confirm the asset. Identify the host, service, product edition, version, and owner. Establish whether the service is intended to be reachable from the public internet.
- Check the listener and network path. Review the address and interface on which the service listens, then inspect host firewalls, perimeter rules, and cloud security-group rules. Restrict access to the clients and networks that need it.
- Verify authentication and authorization for that exact version. Confirm which credentials or tokens are required and what each account is allowed to do. Check permissions for reading, writing, publishing, subscribing, or administering as applicable.
- Classify the data. Determine whether the service contains sensitive, regulated, or operationally important information, and whether its access policy and exposure match the consequences of disclosure or alteration.
- Remediate according to the deployment’s needs. Disable unintended public listeners, require appropriate authentication and authorization, apply suitable transport protection, and narrow network access. Recheck configuration through authorized administrative access.
Service-specific security checks
MQTT on port 1883
Port 1883 is commonly used for MQTT without transport encryption; 8883 is commonly used for MQTT over TLS. The port number alone does not show whether a broker requires client authentication or limits topic access.
The OASIS MQTT Version 3.1.1 specification describes authentication and authorization mechanisms as implementation-dependent. It recommends port 8883 for servers offering TLS and warns: “Implementations passing authentication data in clear text, obfuscating such data elements or requiring no authentication data should be aware this can give rise to Man-in-the-Middle and replay attacks.” That is protocol guidance, not a finding about the brokers in the reported scan. See the OASIS MQTT Version 3.1.1 specification.
- Decide whether the broker needs to be publicly reachable at all.
- Require client authentication where appropriate and verify that broker policy restricts which clients can publish to or subscribe to each topic.
- Use transport protection appropriate to the deployment, especially when credentials or sensitive messages cross untrusted networks.
InfluxDB on port 8086
Port 8086 is used for the InfluxDB HTTP API. Authentication defaults are not universal across InfluxDB products, versions, or deployments. InfluxData’s OSS v1 documentation says its documented default configuration leaves authentication disabled and recommends enabling it for a publicly accessible endpoint. That guidance applies to the documented OSS v1 configuration; it should not be generalized to every current InfluxDB installation.
Identify the installed edition and version, then check the corresponding official guidance for authentication, authorization, token management, and network exposure. InfluxData’s InfluxDB OSS v1 authentication and authorization documentation describes that version’s controls. The 2,503 reported responses do not show whether any individual service had authentication disabled.

Port 8123 is the ClickHouse HTTP interface; port 9000 is used for its native protocol. For an installation you administer, verify which interfaces are enabled and where they listen, then review the user configuration and permissions for the exact ClickHouse version and deployment method. Do not infer user or password defaults from a port response: the reported count is not evidence about authentication.
