Vulnerability in EPiServer.Forms
I'm seeing a lot of these error messages in log file. Any idea where they may be originating from?
EPiServer.Tracking.Code.TrackingValidation: Maximum length for Tracking data value is 255 characters
The track event Value field can have max 255 characters in it otherwise it will return with an error. All of the properties included in the track event are documented here on the World.
