CVE-2026-39111
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedSQL Injection vulnerability in Apartment Visitors Management System Apartment Visitors Management System V1.1 in the email parameter of the forgot password page (forgot-password.php). This allows an unauthenticated attacker to manipulate backend SQL queries and retrieve sensitive user data.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA SQL Injection vulnerability exists in the Apartment Visitors Management System V1.1 within the forgot-password.php script. The 'email' parameter accepts unsanitized user input that is directly incorporated into SQL queries, enabling an unauthenticated attacker to inject malicious SQL syntax and potentially exfiltrate sensitive data from the database.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed application versionLocate and examine any version file, README, or header comment in the Apartment Visitors Management System installation directory to confirm it is version V1.1Affected if The installed version is V1.0 or V1.1 of the Apartment Visitors Management System
-
Locate the forgot-password.php scriptSearch for the file named forgot-password.php in the web application's document root or public directoryAffected if The file forgot-password.php exists in the application installation
-
Examine the email parameter handlingOpen forgot-password.php and search for the 'email' parameter usage in SQL queries - look for code where $_POST['email'] or $_GET['email'] is directly concatenated into a query string without using prepared statements or parameter bindingAffected if The code shows direct string concatenation of the email parameter into SQL queries (e.g., "SELECT * FROM users WHERE email='" . $_POST['email'] . "'") without sanitization or prepared statements
-
Verify input validation absenceCheck if there is any input validation, sanitization, or use of functions like mysqli_real_escape_string, htmlspecialchars, or parameter binding applied to the email parameter before the SQL query executionAffected if No input validation or sanitization functions are applied to the email parameter before it is used in the SQL query
You are affected if you are running Apartment Visitors Management System V1.1 and the forgot-password.php file contains direct SQL query construction using the email parameter without prepared statements or input sanitization.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace dynamic SQL query construction with parameterized queries or prepared statements, validate and sanitize all user inputs, and apply principle of least privilege to database accounts.
