This vulnerability affects SourceCodester Pharmacy Sales and Inventory System 1.0, specifically the supplier function in /index.php?page=supplier. An attacker can manipulate the Name parameter to inject malicious scripts, resulting in cross-site scripting (XSS). The attack can be performed remotely and requires user interaction. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required, partial user interaction, and low impact on integrity. There is no official patch or vendor remediation information available at this time.

Successful exploitation allows an attacker to execute arbitrary scripts in the context of the affected web application, potentially leading to session hijacking, defacement, or other client-side impacts. The vulnerability does not affect confidentiality or availability according to the CVSS vector. There are no known active exploits in the wild.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider applying input validation or output encoding on the Name parameter to mitigate XSS risks. Monitor vendor channels for updates and patches.
