Stored XSS in Task Manager App 1.0 allows remote attackers to execute arbitrary script in a victim's browser via a crafted task note. The Note Section in /TaskManager/Tasks.php accepts and renders script markup without adequate sanitization, causing the submitted payload to execute. Exploitation requires a victim to load the affected task content; code runs only in the site's browser context, enabling session-data access or page actions.
