CVE-2026-39110 is a high-severity SQL Injection vulnerability affecting the Apartment Visitors Management System V1.1. This flaw resides specifically in the contactno parameter of the forgot password page (forgot-password.php). An unauthenticated attacker can exploit this vulnerability to manipulate backend SQL queries, enabling them to retrieve sensitive database contents.
The severity of this vulnerability is rated high with a CVSS score of 8.2. This rating indicates a significant risk to organizations using this application, as it allows attackers to access confidential data without requiring user credentials or interaction.
Given the nature of SQL Injection attacks, the potential for data breaches and unauthorized access should not be underestimated. Organizations utilizing the Apartment Visitors Management System must take immediate action to assess their exposure to this vulnerability.
As of now, the exploitation status is deferred, indicating that a public exploit has not been confirmed. However, the presence of this vulnerability necessitates urgent attention from security teams to prevent any potential exploitation.
Vulnerability Details
The vulnerability description highlights that an attacker can manipulate SQL queries through the vulnerable contactno parameter, which could lead to unauthorized data exposure. The CVSS score of 8.2 confirms the high severity level, indicating a serious risk to confidentiality, as sensitive information may be compromised.
This vulnerability is classified under CWE-89, which pertains to SQL Injection. The attack vector is network-based, allowing remote attackers to exploit the flaw without needing physical access.
The vulnerability was published on April 20, 2026. Organizations should be aware that all versions of the Apartment Visitors Management System prior to remediation are affected.
Technical Analysis
The root cause of CVE-2026-39110 stems from improper validation of user input, specifically in the contactno field on the forgot password page. This oversight allows attackers to inject malicious SQL code into the backend database queries.
The attack vector is network-based, and the complexity is rated low, meaning that minimal technical skills are required to execute the attack. No privileges are required, and user interaction is not necessary for exploitation.
The vulnerability has a high potential impact on confidentiality, as attackers can access sensitive information, while the integrity impact is rated low, indicating a lower risk of data alteration. The availability impact is assessed as none.
Risk & Impact Analysis
The risk to organizations includes unauthorized access to sensitive user data, which could lead to identity theft, data breaches, and potential regulatory penalties. The SQL Injection nature of this vulnerability allows attackers to bypass authentication mechanisms and obtain information that could be damaging to organizations and their clients.
Given the CVSS score of 8.2, organizations should prioritize patching immediately. The potential blast radius is significant, as any system connected to the vulnerable application may be at risk.
