Craft CMS stored XSS in review volume

Summary

XSS can be triggered by review volumes

PoC

1. Access setting tab

Root cause

Function: index.php?p=admin/actions/asset-indexes/process-indexing-session&v=1680710595770
After loading completed, progess will load:
"skippedEntries"
and
"missingEntries"
These parameters is not yet filtered, I just tried "skippedEntries" but I think it will be work with "missingEntries"

My reponse:

{
"session": {
"id": 10,
"indexedVolumes": {
"6": ""alert(1337)"
},
"totalEntries": 2235,
"processedEntries": 2235,
"cacheRemoteImages": true,
"listEmptyFolders": false,
"isCli": false,
"actionRequired": true,
"dateCreated": "Apr 5, 2023, 9:03:16 AM",
"skippedEntries": [
""alert(1337)/assetpreviews/Image.php",
""alert(1337)/assetpreviews/Pdf.php"
],
"missingEntries": {
"folders": [],
"files": []
},
"processIfRootEmpty": false
},
"skipDialog": false
}
