Stored XSS via unescaped task rendering
Published Sep 9, 2025 · Updated Sep 9, 2025
Stored cross-site scripting in SourceCodester Simple To-Do List System 1.0 allows remote authenticated users to execute script in visitors' browsers. The Add New Task flow stores unescaped task content in MySQL, and fetch_tasks.php later inserts that content into HTML without output encoding. An account capable of adding a task and a second user who loads the task list are required; injected script runs with that visitor's application-session privileges.
