Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
We found a possible XSS vector in the `Filter.FilterStreamDescriptorForm` wiki page related to pretty much all the form fields printed in the home page of the application.
### Patches
The issue is patched in versions 12.10.11, 14.0-rc-1, 13.4.7, 13.10.3.
### Workarounds
The easiest workaround is to edit the wiki page `Filter.FilterStreamDescriptorForm` (with wiki editor) and change the lines
```
<input type="text" id="$descriptorId" name="$descriptorId" value="#if($request.get($descriptorId))$request.get($descriptorId)#else$descriptor.defaultValue#end"/>
#else
<input type="text" id="$descriptorId" name="$descriptorId"#if($request.get($descriptorId))value="$request.get($descriptorId)"#end/>
```
into
```
<input type="text" id="$descriptorId" name="$descriptorId" value="#if($request.get($descriptorId))$escapetool.xml($request.get($descriptorId))#else$descriptor.defaultValue#end"/>
#else
<input type="text" id="$descriptorId" name="$descriptorId"#if($request.get($descriptorId))value="$escapetool.xml($request.get($descriptorId))"#end/>
```
