A security flaw has been discovered in Dromara MaxKey up to 3.5.13. Affected by this issue is the function StrUtils.checkSqlInjection of the file StrUtils.java. Performing a manipulation of the argument filtersfields results in sql injection. The attack is possible to be carried out remotely. The exploit has been released to the public and may be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.
This vulnerability is classified as low severity, with a CVSS score of 2.1. Although the severity is low, risk to organizations includes potential unauthorized access to sensitive data through SQL injection, making it important to address.
Organizations should prioritize patching immediately to mitigate this vulnerability, especially if they are using the affected version.
As of now, there is no public exploit confirmed for this vulnerability, but it is crucial for security teams to stay vigilant.
Given the nature of SQL injection vulnerabilities, the potential for exploitation remains, and organizations should take this into consideration.
Vulnerability Details
This vulnerability allows attackers to perform SQL injection through the StrUtils.checkSqlInjection function in Dromara MaxKey. The CVE was published on May 3, 2026, and it has been classified under CWE-74 (Injection) and CWE-89 (SQL Injection).
The CVSS score of 2.1 indicates low severity, with the vulnerability being network exploitable and requiring low privileges to exploit. The attack complexity is also low, making it feasible for attackers with limited skill.
Organizations using versions up to 3.5.13 of Dromara MaxKey should be particularly aware of this vulnerability and take appropriate measures to secure their systems.
Technical Analysis
The root cause of this vulnerability lies in the improper handling of user input within the StrUtils.checkSqlInjection function. By manipulating the argument filtersfields, an attacker can craft a malicious SQL query to execute arbitrary SQL commands on the database.
The attack vector is over the network, and the complexity of the attack is low, meaning that an attacker can execute it without any significant prerequisites.
This vulnerability does not require user interaction, and the impact on confidentiality, integrity, and availability is rated as low.
Risk & Impact Analysis
The risk to organizations includes the potential for unauthorized access to sensitive data through SQL injection attacks. Even though the CVSS score is low, the presence of this vulnerability can allow attackers to manipulate databases and extract sensitive information, which can have severe repercussions.
The blast radius potential is significant if exploited, as it could lead to data breaches affecting multiple users or systems. Organizations should assess the urgency of remediation based on their specific environment and the criticality of the data managed by the affected application.
