Thread: Security issue in grid

  1. #1

    Default Security issue in grid

    When adding '<img onerror="alert('Hi There')" src='./ff'></img>' into column Common Name of the sample of the kitchen sink 'Cell Editing Plants' the script gets executed and the alert pops up.
    This is a critical security issue.

    The classic toolkit largely doesn't handle XSS in any component so you'd need to add a renderer to your column(s) that may be at risk and use Ext.String.htmlEncode.
