CVE-2026-6188
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 SourceCodester Pharmacy Sales and Inventory System 1.0. Impacted is an unknown function of the file /ajax.php?action=delete_sales. This manipulation of the argument ID causes sql injection. It is possible to initiate the attack remotely. The exploit has been published 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 · moderate confidenceSQL injection vulnerability in SourceCodester Pharmacy Sales and Inventory System 1.0 allows remote attackers to inject malicious SQL queries via the ID parameter in the /ajax.php?action=delete_sales endpoint. The lack of input sanitization or parameterized queries in the delete_sales function enables attackers to manipulate database queries, potentially allowing data exfiltration, modification, or unauthorized deletion of records.

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 the application is SourceCodester Pharmacy Sales and Inventory SystemLocate the application installation directory and verify it is the SourceCodester Pharmacy Sales and Inventory System by checking for typical installation paths such as /var/www/html/, /www/, or C:\xampp\htdocs\, and identify the application name from project files or banners.Affected if The installed application is SourceCodester Pharmacy Sales and Inventory System
-
Verify the application version is 1.0Check for version indicators in the application such as a version.php file, README file, or any file containing 'version 1.0' or 'v1.0' within the installation directory.Affected if The installed version is 1.0
-
Locate ajax.php and verify the delete_sales function existsSearch for the ajax.php file within the web root and open it to locate the delete_sales function definition.Affected if ajax.php exists and contains a delete_sales function
-
Inspect the delete_sales function for proper SQL parameterizationWithin ajax.php, examine the delete_sales function code and search for the ID parameter handling. Look for the absence of prepared statements, parameterized queries, or input sanitization functions such as mysqli_prepare, PDO::prepare, or escaping functions. Check if the ID parameter is directly concatenated into the SQL query string.Affected if The ID parameter is used directly in SQL queries without prepared statements, parameterization, or input sanitization
The user is affected if they are running SourceCodester Pharmacy Sales and Inventory System version 1.0 with the ajax.php file containing a delete_sales function where the ID parameter is not protected by parameterized queries 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 dataImplement prepared statements/parameterized queries for all database operations in ajax.php, specifically for the delete_sales function. Additionally, apply input validation and output encoding, and consider deploying a WAF as a defense-in-depth measure.
