Thanks for trying to fix the problem but we tested again and the same error remains. I think is related to the use of "href" without validate it. Check this screenshot:

In this context it has to be a false positive report:

1. "href" is a string (and a valid URL at that), so unless I run an eval on one of the extracted params, there is not much damage that can be done.
2. urlParam is only actually used in a few demo apps: https://github.com/hpcc-systems/Visualization/search?q=urlParams
