Apache InLong SQL Injection Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-63038

Apache InLong is a data integration platform often deployed to ingest, process, and manage data streams. Components handling database-related parameters like dbName, tableName, and schemaName in such systems are frequently exposed as part of management interfaces, API endpoints, or data ingestion services that may be reachable over a network.

Horizon Alert

Summary of the vulnerability and why it matters

A vulnerability in Apache InLong, a data integration platform, could allow attackers to inject malicious SQL commands. This type of attack can compromise sensitive data and disrupt operations. The main concern is confirming if this technology is in use and exposed.

Data integration software has a SQL injection flaw.
Prevents unauthorized database access and manipulation.
Confirm exposure of Apache InLong in your environment.

Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by sending specially crafted requests to the Apache InLong system. By manipulating parameters such as `dbName`, `tableName`, `schemaName`, and `username`, they can inject malicious SQL commands. If successful, this could allow them to read, modify, or delete sensitive data within the database, or potentially take control of the database.

Unauthenticated network access required.
Inject arbitrary SQL via specific parameters.
Full database compromise possible.

Live Threat

Current exploitation, exposure, and threat context

An attacker could inject arbitrary SQL code into Apache InLong through specific parameters, potentially affecting the integrity and availability of the system's data. This could occur when these parameters are used in SQL commands and are exposed to unauthenticated users.

Database names and table structures at risk.
Arbitrary SQL code injection possible.
Compromised data integrity and service availability.

Operational Fix

Recommended remediation, mitigation, and detection steps

The platform or application owners for Apache InLong are responsible for addressing this SQL injection vulnerability. The first practical step is to inventory all deployments of Apache InLong, determine their network exposure and business criticality, and identify the accountable owner for each instance. Remediation planning should then be prioritized based on these findings.

Platform owners should manage the issue.
Verify InLong instances and their exposure.
Plan upgrades or apply relevant patches.

Frequently asked questions

What is Apache InLong?

Apache InLong is an open-source data integration platform. It is designed to ingest, process, and manage large-scale data streams, moving information between various sources and destinations within a data pipeline architecture.

What does CVE-2026-63038 mean for Apache InLong?

This CVE represents an SQL Injection vulnerability, classified as CWE-89. It means the software does not properly sanitize user input, allowing an attacker to insert their own malicious SQL commands into database queries managed by the system.

How can an attacker trigger this SQL injection?

An attacker can trigger this by sending requests containing malicious input through specific parameters like dbName, tableName, schemaName, or username. Simply interacting with the platform's standard interface is not enough; the attacker must provide crafted input that the system incorrectly processes as part of an SQL command.

Do I need to worry about this if my InLong instance is internal?

According to Halo Surface Signal, this software is often deployed in ways that are reachable over a network, such as management interfaces or API endpoints. While internet-facing instances are at the highest risk, internal systems may still be vulnerable if they are accessible to unauthorized users within your network.

What should I do first to address this vulnerability?

Your first step is to locate all instances of Apache InLong running in your environment. Once you have a complete inventory, assess which instances are accessible over the network and determine who is responsible for maintaining those specific systems to begin the upgrade process.
