Vulnerability Title
Wallos: Reflected XSS via unescaped token and email parameters in passwordreset.php
Source: NVD (National Vulnerability Database)
Vulnerability Description
Wallos is an open-source, self-hostable personal subscription tracker. Prior to version 4.6.2, passwordreset.php outputs $_GET["token"] and $_GET["email"] directly into HTML input value attributes using <?= $token ?> and <?= $email ?> without calling htmlspecialchars(). This allows reflected XSS by breaking out of the attribute context. This issue has been patched in version 4.6.2.
