Upgraded from 2020.2.4 to 20202.5 - Node Details - WEB BROWSE shows the following on some devices http://{ { HrefIPAddress }}

That's not new to this version, its been a common bug since as far back as I can remember.  At times when I was more motivated I just wrote a trigger on the nodesettings table to replace it any time that comes up with the actual ip of the node.

In the 2020.2.5 version there is a syntax error in NodeDetails.ascx.
Solarwinds have added the file with following in several lines: DefaultSanitizer.SanitizeHtml
This include the line for web browsing, which breaks the line.
It is line number 224 and looks like this:  <td class="Property"><a href="<%= DefaultSanitizer.SanitizeHtml(WebBrowseTemplate) %>"><%= DefaultSanitizer.SanitizeHtml(WebBrowseTemplate) %></a></td>

The web browsing line worked in 2020.2.4 and looked like this:  <td class="Property"><a href="<%=WebBrowseTemplate %>"><%=WebBrowseTemplate %></a></td>

NodeDetails.ascx is located in this directory: C:\inetpub\SolarWinds\Orion\NetPerfMon\Resources\NodeDetails\

This is indeed a result of HTML sanitization. We are tracking this under CORE-17460.

Has the been resolved in the 2020.2.6 release? I don't recall seeing it in the release notes.
