CVE-2026-75498 in QloApps
Summary
by MITRE • 08/25/2026
Webkul QloApps does not validate request parameters before a database query. A remote, authenticated attacker with administrative privileges could send a crafted SQL query to the 'bo_query' parameter in the 'Address.php' file. Fixed in 123c97c.

The vulnerability identified involves a critical lack of input validation within the QloApps e-commerce platform, specifically affecting the Address management functionality. This flaw allows for SQL injection attacks against the underlying database system. The root cause lies in the improper handling of user-supplied data within the bo_query parameter located in the Address.php file. Because the application fails to sanitize or validate these request parameters before incorporating them into dynamic SQL queries, it creates a direct pathway for malicious actors to manipulate the intended database operations. This type of vulnerability is classically categorized under CWE-89 Improper Neutralization of Special Elements used in an SQL Command, which highlights the failure to neutralize special characters that could alter the structure or intent of the executed query.
The operational impact of this flaw is significant due to the specific privilege level required for exploitation. The description notes that a remote attacker must possess administrative privileges to leverage this vulnerability. While this requirement limits the attack surface compared to unauthenticated SQL injection flaws, it does not eliminate the risk entirely. An authenticated administrator with malicious intent or an account compromised through other means can exploit this weakness to execute arbitrary SQL commands. This capability enables the extraction of sensitive data from the database, including customer personal information, payment details, and internal system configurations. Furthermore, depending on the specific capabilities granted to the database user by the web application's configuration, a successful exploitation could potentially lead to unauthorized modification or deletion of critical business data, thereby compromising the integrity and availability of the platform.
From a tactical perspective, this vulnerability aligns with techniques found in the MITRE ATT&CK framework, particularly those related to Data Injection such as SQL injection (T1190). The attacker utilizes valid credentials to bypass initial access controls and then injects malicious code into the application layer to interact directly with the data store. This represents a classic case of privilege escalation within the context of database interaction, where administrative rights are abused to perform actions beyond normal business logic requirements. The existence of such a flaw in an e-commerce platform poses severe risks to compliance standards like PCI DSS and GDPR, as it facilitates unauthorized access to protected health information or financial data stored within the application's backend systems.
To mitigate this vulnerability, immediate remediation is required by applying the fix referenced in commit 123c97c. This update likely introduces proper input validation mechanisms, such as parameterized queries or prepared statements, which ensure that user-supplied data is treated strictly as data rather than executable code. In addition to patching the software, organizations should enforce strict principle of least privilege for database accounts used by web applications, ensuring that even if SQL injection occurs, the potential damage is contained within a limited scope. Regular security audits and static application security testing (SAST) can help identify similar patterns in other parts of the codebase where request parameters are passed to database queries without adequate sanitization.
