CVE-2026-12776
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 flaw has been found in Montodel House-Rental-Management up to 90010017b81265eb1ef3810268909f7719a33863. This affects an unknown part of the file /index.php?page=houses. This manipulation of the argument ID causes sql injection. The attack is possible to be carried out remotely. The exploit has been published and may be used. This product adopts a rolling release strategy to maintain continuous delivery. Therefore, version details for affected or updated releases cannot be specified. 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 the ID parameter of /index.php?page=houses in Montodel House-Rental-Management allows remote attackers to inject malicious SQL queries via unsanitized input. The vulnerability exists because the application does not use parameterized queries when processing the ID argument.

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 if Montodel House-Rental-Management is installedSearch for the application files on the web server, typically in the document root. Look for directories or files containing 'house-rental-management' or 'montodel'. Check the application for any version indicator files such as README, VERSION, or a config file that may contain a version number.Affected if The Montodel House-Rental-Management application is present on the server and the version is unknown or falls within any pre-patch release.
-
Verify the houses endpoint is accessibleAttempt to access the URL pattern /index.php?page=houses on the web server. This can be done via a browser, curl command, or any HTTP client. Confirm the page loads or returns a valid HTTP response.Affected if The /index.php?page=houses endpoint is accessible and functional.
-
Locate the source code for the houses pageOn the web server, navigate to the web root directory and locate the PHP file that handles the 'houses' page. This is typically index.php or a file in the includes folder that processes the 'page=houses' request. Open the file and locate the code that handles the ID parameter.Affected if The source code processes the ID parameter from the houses page without using prepared statements or parameterized queries.
-
Inspect SQL query construction for the ID parameterIn the houses page source code, examine all SQL queries that incorporate the ID parameter. Look for patterns where the ID is concatenated directly into the query string (such as $sql = "SELECT * FROM houses WHERE id = " . $_GET['id']) rather than using placeholders with bind parameters (such as $stmt->prepare and $stmt->bind_param).Affected if The ID parameter is directly interpolated into SQL queries without parameterization or input sanitization.
If the Montodel House-Rental-Management application is installed and the source code for the houses page processes the ID parameter using direct string concatenation instead of prepared statements, the environment is affected by this SQL injection vulnerability.

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 queries with prepared statements/parameterized queries in the houses page, or implement input validation and escaping. Deploy a WAF as a temporary compensating control until the code fix is implemented.
