| Title | sourcecodester Pharmacy Sales and Inventory System V1.0 cross site scripting |
|---|
| Description | During the security review of "Pharmacy Sales and Inventory System", I discovered a critical XSS vulnerability in the "/index.php?page=categories" file. This vulnerability stems from insufficient user input validation and output encoding of the 'id' parameter, allowing attackers to inject malicious script code. Therefore, attackers can execute arbitrary scripts in the victim's browser, steal sensitive information, and perform operations on behalf of the victim. Immediate remedial measures are needed to ensure system security and protect user data. |
