CVE-2026-8083
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 SourceCodester Pharmacy Sales and Inventory System 1.0. This affects an unknown part of the file /ajax.php?action=save_user. The manipulation of the argument ID results in sql injection. The attack can be executed 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 · moderate confidenceSQL injection vulnerability in SourceCodester Pharmacy Sales and Inventory System 1.0 at the /ajax.php?action=save_user endpoint, specifically in the ID parameter. The vulnerability allows remote attackers to inject malicious SQL queries via manipulated ID arguments.

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 installed version of SourceCodester Pharmacy Sales and Inventory SystemCheck your web application files for version information, typically found in a README, version.php, or similar file in the application root directory. Compare the found version to 1.0.Affected if The installed version is 1.0 and matches the vulnerable version listed in the affected products.
-
Locate the ajax.php file in your web rootNavigate to your web server document root and confirm the presence of ajax.php. This is the vulnerable script file.Affected if The ajax.php file exists and is accessible via the web server.
-
Examine the save_user function implementation in ajax.phpOpen ajax.php in a text editor and locate the code block handling the 'save_user' action. Review how the ID parameter is processed within this function.Affected if The save_user function exists and processes an ID parameter without using parameterized queries (prepared statements).
-
Verify the ID parameter is directly used in SQL queriesSearch within the save_user function for SQL query construction that incorporates the ID parameter directly into the query string, without proper escaping or parameter binding.Affected if The ID parameter is concatenated directly into SQL queries without sanitization or prepared statement usage.
-
Confirm the endpoint is accessible and accepts user inputCheck if the web server configuration allows access to ajax.php and if the application accepts ID parameter input through HTTP requests to ?action=save_user.Affected if The /ajax.php?action=save_user endpoint is accessible and the ID parameter can be manipulated by remote users.
You are affected if you are running SourceCodester Pharmacy Sales and Inventory System version 1.0 and the ajax.php save_user function processes the ID parameter using direct SQL concatenation instead of parameterized 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 interactions, especially in the save_user function. Apply input validation and use least-privilege database accounts. If no patch exists, consider disabling the affected endpoint until a secure version is available.
