CVE-2026-5560
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 found in PHPGurukul Online Shopping Portal Project 2.1. The impacted element is an unknown function of the file /payment-method.php of the component Parameter Handler. Performing a manipulation of the argument paymethod results in sql injection. It is possible to initiate the attack remotely. The exploit has been made public and could be used.
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 · high confidenceSQL injection vulnerability in PHPGurukul Online Shopping Portal 2.1 in the payment-method.php file. The 'paymethod' parameter is not properly sanitized before being used in SQL queries, allowing remote attackers to inject malicious SQL commands.

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 the PHPGurukul Online Shopping Portal is installedLocate the application files, typically in the web server document root. Look for index.php or common PHP files with 'shopping' or 'online' in the path.Affected if The application is present on the server
-
Confirm the application version is 2.1Check for a version file, readme, or footer/includes within the application for the version number.Affected if The installed version matches 2.1 or falls within the affected range
-
Locate the vulnerable payment-method.php fileNavigate to the web application directory and find payment-method.php, typically in the root or a parent directory.Affected if The file payment-method.php exists and is accessible via the web server
-
Check if the paymethod parameter is processed without sanitizationReview the source code of payment-method.php and look for SQL queries that incorporate the 'paymethod' POST or GET parameter directly, without using prepared statements or escaping functions.Affected if The code contains unsanitized use of the paymethod parameter in SQL queries (for example: SELECT * FROM table WHERE field = '$_POST[paymethod]')
-
Test if the parameter accepts SQL injection payloadsSend an HTTP request to payment-method.php with a test payload in the paymethod parameter (such as a single quote or a boolean-based test like ' OR '1'='1) and observe the response for SQL errors or unexpected behavior.Affected if The application returns SQL syntax errors or behaves differently based on injected SQL content
If the application is PHPGurukul Online Shopping Portal version 2.1 and the payment-method.php file handles the paymethod parameter without parameterized queries, the environment is vulnerable to CVE-2026-5560.

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 prepared statements/parameterized queries for all database operations involving user input, particularly the paymethod parameter. Apply input validation and escaping as defense-in-depth.
