## Technical details

This is a stored XSS vulnerability in the avatar_mouse_over_text parameter within the donor avatar feature. The vulnerability exists because user-supplied input is not properly sanitized or escaped before being stored in the database and later rendered in avatar tooltip elements. An authenticated attacker can inject arbitrary JavaScript through the avatar_mouse_over_text field, which is then executed in the context of any user's browser when they hover over or interact with the affected avatar. The attack requires authentication but no additional user interaction beyond viewing the tooltip. A patch would need to implement proper output encoding (HTML escaping) of the tooltip text.
