Description
Wallos 4.4.0 before 5.10.3 contains a stored cross-site scripting vulnerability in endpoints/cronjobs/sendnotifications.php that allows registered users to inject scripts via unescaped notification service responses. Attackers can point their Mattermost webhook URL or Web Push endpoint at a controlled server returning JavaScript, which executes in the administrator's session when sendnotifications.php is opened.
