Technical details
The vulnerability is a stored cross-site scripting (CWE-79) flaw in the /api/vendors_handler.php and /vendors.php components. The Vendor Management module fails to sanitize or validate user input in vendor fields (name, mobile, email, address, PAN, GST) before storing them in the database or rendering them in the HTML response. An authenticated attacker can inject JavaScript payloads via the vendor creation endpoint; the malicious script is persisted in the database and executed whenever any authenticated user views the vendor list page. The attack requires authentication but enables session cookie theft and account takeover of any user, including administrators. Input validation and output encoding via htmlspecialchars() or similar functions are required to fix this issue.
