CVE-2025-65342Public exploitNetwork attack vector

Stored XSS via unescaped donor city

Published Jul 30, 2026 · Updated Jul 30, 2026

Stored XSS in code-projects Blood System 1.0 allows remote attackers to execute script in viewers' browsers through a crafted donor city. The application persists the city POST parameter accepted by don.php and later inserts it into profile.php output without sanitization or output encoding. Exploitation requires an unauthenticated submission and a viewer to load the stored donor data; attacker-supplied script then runs in that viewer's application origin.
