CVE-2026-12775
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 · uneditedA vulnerability was detected in Montodel House-Rental-Management up to 90010017b81265eb1ef3810268909f7719a33863. Affected by this issue is some unknown functionality of the file /login.php. The manipulation of the argument Username results in sql injection. The attack can be executed remotely. The exploit is now public and may be used. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. The vendor was contacted early about this disclosure but did not respond in any way.
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 confidenceSQL injection vulnerability in Montodel House-Rental-Management /login.php allows remote attackers to inject malicious SQL queries via the Username parameter. The lack of input sanitization or parameterized queries enables attackers to manipulate database queries, potentially gaining unauthorized access to the application and underlying data.

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.
-
Verify Montodel House-Rental-Management is installedLocate the application directory or check web server document root for the House-Rental-Management application files, typically under a web-accessible pathAffected if The application is present on the system
-
Confirm login.php existsLocate the /login.php file within the application web directory. This is typically found in the root or /admin folder of the House-Rental-Management installationAffected if The login.php file exists in the application
-
Verify the login form accepts a Username parameterAccess the login page via HTTP and inspect the HTML form to confirm it contains a Username input field that gets submitted to login.phpAffected if A Username field is present and submits to login.php
-
Check for lack of prepared statements in login.phpReview the login.php source code to verify whether database queries use prepared statements (parameterized queries) or raw string concatenation with the Username parameter. Search for patterns like $username directly in SQL queries without bind parametersAffected if Code contains SQL queries that concatenate or embed the Username parameter directly without using prepared statements or input sanitization functions
A user is affected if the Montodel House-Rental-Management application is installed with a login.php that processes the Username parameter using unsanitized string concatenation in SQL queries.

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 dataImplement parameterized queries (prepared statements) for all database operations in login.php and validate/sanitize all user inputs. Consider implementing a Web Application Firewall as an interim control until code-level fixes are applied.
