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.
