Summary
by MITRE • 08/20/2026
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Apache InLong. This allows an attacker to inject arbitrary SQL code through the dbName, tableName, schemaName, and username parameters.
This issue affects Apache InLong: from 2.0.0 before 2.4.0.
Users are advised to upgrade to Apache InLong's 2.4.0 or cherry-pick [1] to solve it.

The vulnerability identified as Improper Neutralization of Special Elements used in an SQL Command, commonly known as SQL Injection, represents a critical security flaw within the Apache InLong data integration platform. This specific weakness allows malicious actors to inject arbitrary Structured Query Language code by manipulating input parameters such as dbName, tableName, schemaName, and username. The root cause lies in the application's failure to properly sanitize or validate user-supplied input before incorporating it into database queries. When these parameters are passed directly into SQL statements without adequate encoding or parameterization, the database engine interprets the injected code as part of the command structure rather than as data. This fundamental breakdown in input validation enables an attacker to alter the logic of backend database operations, potentially bypassing authentication mechanisms, extracting sensitive information, modifying existing records, or even executing administrative commands on the underlying database server depending on the privileges assigned to the application's database account.
This vulnerability affects Apache InLong versions ranging from 2.0.0 up to but not including version 2.4.0. The impact of this flaw is severe because it compromises the integrity and confidentiality of data managed by the platform. An attacker leveraging this SQL injection can perform unauthorized read operations to exfiltrate sensitive business data, alter records to disrupt service availability or manipulate analytics results, and potentially escalate privileges if the database user has elevated permissions such as file access or command execution capabilities. In a production environment handling large-scale data pipelines, such an exploit could lead to significant operational disruption, regulatory non-compliance due to data breaches, and substantial financial loss. The ability to inject code through multiple entry points including schema and table names increases the attack surface, making it easier for adversaries to find exploitable vectors within complex data ingestion workflows.
From a classification perspective, this issue aligns with CWE-89: Improper Neutralization of Special Elements used in an SQL Command, which is consistently ranked among the most dangerous software weaknesses by industry standards such as OWASP and MITRE. In terms of offensive security tactics, this vulnerability facilitates techniques categorized under ATT&CK ID T1190: Exploit Public-Facing Application, where attackers leverage flaws in internet-facing services to gain initial access or further compromise internal systems. The exploitation typically involves crafting specific payloads that terminate the original SQL statement and append malicious commands, often utilizing common delimiters like single quotes followed by logical operators such as OR 1=1 to bypass authentication checks or UNION SELECT statements to extract data from other tables within the database schema.
To mitigate this risk, organizations running affected versions of Apache InLong must take immediate action. The primary remediation strategy is to upgrade the platform to version 2.4.0 or later, where these input validation issues have been addressed by the development team. For environments that cannot undergo an immediate full upgrade due to compatibility constraints or operational dependencies, users are advised to cherry-pick the specific fix referenced in issue number 12135 from the Apache InLong GitHub repository. This patch likely introduces stricter parameterization of SQL queries and enhanced input validation logic for the affected parameters. Additionally, as a defense-in-depth measure, administrators should ensure that database accounts used by the application adhere to the principle of least privilege, restricting permissions to only those necessary for normal operation. Implementing Web Application Firewalls with robust SQL injection detection rules can also provide an additional layer of protection against exploitation attempts while patching efforts are underway.
