This vulnerability involves a cross-site scripting flaw in SourceCodester Pharmacy Sales and Inventory System 1.0. Specifically, the ID parameter in the /index.php?page=product script can be manipulated to inject malicious scripts. The vulnerability is remotely exploitable and requires user interaction to trigger. The CVSS 4.0 vector indicates network attack vector, low attack complexity, no privileges required but user interaction needed, and limited impact on confidentiality and integrity. No official fix or patch has been disclosed by the vendor as of the publication date.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary scripts in the context of the affected application, potentially leading to session hijacking, defacement, or other client-side attacks. However, the impact is limited by the requirement for user interaction and the lack of elevated privileges needed to exploit it. 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 ID parameter to mitigate the risk. Additionally, educating users to avoid interacting with suspicious links can reduce exploitation likelihood.
