Stored XSS via unescaped notification-bar text
Published Aug 1, 2024 · Updated Aug 1, 2024
Stored cross-site scripting in Premio My Sticky Bar before 2.7.2 allows remote authenticated users to execute script via bar text. The bar editor stores notification-bar text without sanitizing or escaping it, then renders the saved value in the edit view. Administrator privileges are required, and the script runs when an administrator edits the bar, exposing that session's data or actions.
