CVE-2025-9728Public exploitNetwork attack vector

Credential theft via unencoded login-form input

Published Aug 31, 2025 · Updated Sep 2, 2025

Reflected XSS in givanz Vvveb 1.0.7.2 allows remote attackers to execute script in a victim's browser through crafted login-form input. The login template writes posted Email or Password values directly into an HTML value attribute without encoding, allowing quotes to introduce script-bearing markup. Exploitation requires a victim to submit attacker-controlled input; demonstrated scripts can capture login keystrokes and send them off-site.
