This vulnerability affects SourceCodester Pharmacy Sales and Inventory System 1.0. It arises from improper sanitization of the medicine_presentation parameter in the create_medicine_presentation function, enabling an attacker to inject malicious scripts (XSS). The attack vector is network-based, requires low attack complexity, no privileges, but does require user interaction. The vulnerability does not involve confidentiality or availability impacts but has a low integrity impact. The vendor has not provided an official fix or remediation level, and no patch links are available. The system is not a cloud service, so remediation depends on vendor or user action.

Successful exploitation allows an attacker to execute arbitrary scripts in the context of the affected application, potentially leading to session hijacking, defacement, or other client-side impacts. The integrity impact is low, and there is no direct impact on confidentiality or availability. The vulnerability requires user interaction to exploit and does not require elevated privileges.

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 medicine_presentation parameter to mitigate XSS risks. Restricting access to the vulnerable function and educating users about phishing risks may reduce exploitation likelihood. Monitor for vendor updates and apply patches promptly once released.
