When an authenticated user creates a task, the defined_name value is stored and later rendered in the Overview page without HTML sanitization. An attacker can inject malicious script into defined_name, which is then executed in the browser context of users who view the affected task, potentially enabling session compromise and unauthorized actions as the victim.
