CVE-2026-5206
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 security vulnerability has been detected in code-projects Simple Gym Management System 1.0. This vulnerability affects unknown code of the component Payment Handler. The manipulation of the argument Payment_id/Amount/customer_id/payment_type/customer_name leads to sql injection. Remote exploitation of the attack is possible. The exploit has been disclosed publicly and may 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 Simple Gym Management System 1.0's Payment Handler component allows remote attackers to inject malicious SQL queries via multiple parameters (Payment_id, Amount, customer_id, payment_type, customer_name). The lack of parameterized queries or input sanitization on these payment-related fields enables attackers to manipulate database queries.

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.
-
Confirm Simple Gym Management System installationCheck your web server for files associated with Simple Gym Management System, typically in the web root directory. Look for files like login.php, index.php, or a 'gym' folder. Check for version identifiers in source code comments, README files, or meta tags in the application.Affected if The application installed is Simple Gym Management System version 1.0 or earlier without patches applied.
-
Locate the Payment Handler componentSearch the application source code for files related to payment processing. Look for keywords such as 'payment', 'Payment Handler', 'payment_process', or similar in PHP files within the application directory structure.Affected if A Payment Handler component exists and processes payment-related user input.
-
Identify vulnerable parameter usageExamine the Payment Handler code for direct usage of parameters Payment_id, Amount, customer_id, payment_type, and customer_name in SQL queries without visible sanitization or prepared statement usage. Search for patterns like $_POST or $_GET directly concatenated into SQL strings.Affected if Any of these parameters are used in SQL queries without parameterized binding or visible input sanitization functions.
-
Check database query implementationReview the database interaction code in payment-related files. Look for usage of mysqli_query, mysql_query, PDO::query, or similar database functions where user-supplied values are inserted directly into the query string.Affected if SQL queries are constructed by concatenating user-supplied input from the payment parameters rather than using prepared statements or parameterized queries.
If Simple Gym Management System 1.0 is running with an exposed Payment Handler component that accepts the listed parameters and processes them via direct string concatenation into SQL queries, the environment is affected by this 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 parameterized queries/prepared statements for all Payment Handler parameters, implement input validation, and apply the principle of least privilege to database accounts. Consider deploying a WAF as an additional layer of defense.
