Apache InLong SQL Injection in Order By Clause

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-63037

The vulnerability exists in the Apache InLong Manager backend database, which typically operates as an internal data integration and management component. While it is network-reachable, these services are generally deployed within private infrastructure to manage data pipelines rather than being exposed directly to the public internet.

Operational Fix

Recommended remediation, mitigation, and detection steps

The Apache InLong platform's SQL injection vulnerability likely falls under the purview of platform or infrastructure teams responsible for its deployment and maintenance. The immediate practical step is to identify all instances of Apache InLong, assess their exposure and business criticality, and determine the accountable owner for each. This information will inform a prioritized remediation plan, potentially involving vendor coordination or temporary risk reduction measures until a planned upgrade can occur during a maintenance window.

Platform or infrastructure teams own this.
Verify InLong instances and their exposure.

Frequently asked questions

What is Apache InLong?

Apache InLong is a data integration platform used to manage and ingest large-scale streaming data. It functions as a central nervous system for data pipelines, orchestrating how information moves between different storage and processing systems. The Manager component specifically oversees the configuration and control of these data flows.

What does SQL injection mean for CVE-2026-63037?

This CVE involves CWE-89, or Improper Neutralization of Special Elements used in an SQL Command. In simple terms, the software fails to properly sanitize input before using it in a database query. By targeting the ORDER BY clause, an attacker can trick the system into running unauthorized commands, which could reveal or change sensitive data stored in the database.

How can an attacker trigger this vulnerability?

An attacker triggers this by sending a specially crafted request to the Apache InLong Manager backend. The vulnerability relies on the application incorrectly processing input within the ORDER BY clause of a database query. Simply using the platform for standard data transfers without sending these specific, malicious query requests will not trigger the flaw.

Is my instance of Apache InLong at risk?

According to Halo Surface Signal, risk depends on accessibility. While Apache InLong is network-reachable, the Manager component is typically deployed within private, internal infrastructure to govern data pipelines. If your instance is isolated from the public internet, the likelihood of external exploitation is significantly lower compared to a service directly exposed to the web.

How do I respond to this Apache InLong vulnerability?

The primary response is to identify all running instances of Apache InLong in your environment. Once you have an inventory, coordinate with your infrastructure or platform teams to plan an upgrade to version 2.4.0 or later. If an immediate upgrade is not feasible, assess the business criticality of those specific instances to prioritize your remediation efforts.
