I have a component which permits authenticated users to fill out customer records which contain a number of fields. In general, the fields use a joomla form field filter of 'string'. When any of these fields contain a substring of ' /' (space slash) or start with a slash, dfishield interprets this as a path character and blocks the post.

I realize I can disable dfishield entirely, or add an exception just for this component, but surely this would be a relaively common occurrence. What would be the 'best' way to manage this case? Write a custom filter for all this component's form fields?

Thanks for your help,
Custom Fields
Joomla! version (in x.y.z format) 3.9.11
PHP version (in x.y.z format) 7.2.22

usually paths (or URLs) should be encoded using base64. This is the same mechanism is using Joomla for redirects.
That being said, the only solution for you is to create a WAF exception inside Admin Tools configuration and disable security checks for a specific view of that component.
