Apache InLong SQL Injection Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.8)

CVE-2026-63039

Apache InLong is a data ingestion and integration framework. While it is designed for enterprise data pipelines and often resides within internal networks, its components manage data flows that can plausibly be exposed or reachable in distributed, cloud-native, or edge-connected deployment environments.

Horizon Alert

Summary of the vulnerability and why it matters

A critical vulnerability has been identified in Apache InLong, a data integration framework. This issue, known as SQL injection, allows unauthorized manipulation of database commands. While the specific impact depends on how InLong is deployed and utilized within your environment, it could potentially allow attackers to access or alter sensitive data managed by the system.

  • Vulnerability allows database command injection.
  • Matters for systems managing data pipelines.
  • Confirm relevance and potential exposure.

Attack Path

How an attacker could exploit the issue

An attacker can reach the vulnerable component by sending specially crafted input over the network to Apache InLong. This malicious input is then improperly processed, allowing the attacker to inject commands into the SQL statement. Successful exploitation could lead to an attacker gaining control over the database.

  • Network access required.
  • Inject malicious strings into SQL statements.
  • Complete database compromise.

Live Threat

Current exploitation, exposure, and threat context

SQL injection vulnerabilities in Apache InLong could allow an attacker to manipulate database queries, potentially impacting the integrity and confidentiality of data processed by the system. This risk exists when the affected software is accessible over a network.

  • Database integrity and confidentiality.
  • Unauthenticated network access.
  • Unauthorized data access or modification.

Operational Fix

Recommended remediation, mitigation, and detection steps

The Apache InLong SQL injection vulnerability impacts data ingestion pipelines. Teams responsible for data integration platforms, including application owners and potentially platform or infrastructure teams, should lead the response. The first practical step is to identify all Apache InLong instances, assess their exposure and business criticality, and then engage the accountable owners to plan remediation.

  • Data platform owners should lead remediation efforts.
  • Verify InLong instance exposure and criticality.
  • Plan and execute the upgrade or cherry-pick.

Frequently asked questions

What is Apache InLong?

Apache InLong is a high-performance, real-time data ingestion and integration framework. It is used by organizations to manage complex data pipelines, collecting and processing large streams of information from various sources into storage or analysis systems. Because it sits at the heart of data movement, it is a critical component for maintaining reliable data flows across distributed architectures.

What does SQL injection mean for CVE-2026-63039?

This vulnerability is classified as CWE-89, or SQL Injection. It means the software fails to properly sanitize input before using it in database commands. Instead of treating input as simple data, the system accidentally processes it as executable code. This allows an attacker to manipulate the underlying database queries, potentially enabling them to view, modify, or delete sensitive data managed by the framework.

How can an attacker trigger this vulnerability?

An attacker triggers this flaw by sending specially crafted input strings over the network to the vulnerable Apache InLong component. If the software is properly secured and does not receive untrusted input directly from an external network, the risk is lower. However, if any part of the system is configured to accept or process unvalidated data, it may be susceptible to this injection path.

Why should I care about this if my system is internal?

While Apache InLong is often used for internal data pipelines, Halo Surface Signal notes that it is frequently deployed in cloud-native or edge-connected environments. This means components are often reachable via wider networks than anticipated. If an attacker can reach your InLong instance from any network segment, they could potentially exploit this vulnerability regardless of its internal, backend role.

Do I need to patch Apache InLong immediately?

Yes, you should prioritize remediation. First, conduct an inventory to identify all instances of Apache InLong running versions 2.0.0 through 2.3.9 in your environment. Once identified, evaluate their business criticality and network exposure. Work with your data platform teams to upgrade to version 2.4.0 or apply the specific code fix referenced in the advisory to neutralize the vulnerability.
