GHSA-f776-w9v2-7vfj XWiki Change Request Application UI XSS and remote code execution through change request title

• Maven org.xwiki.contrib.changerequest:application-changerequest-ui: >= 0.11, < 1.9.2 → fixed in 1.9.2

Impact It's possible for a user without any specific right to perform script injection and remote code execution just by inserting an appropriate title when creating a new Change Request. This vulnerability is particularly critical as Change Request aims at being created by user without any particular rights. Patches The vulnerability has been fixed in Change Request 1.9.2. Workarounds It's possible to workaround the issue without upgrading by editing the document `ChangeRequest.Code.ChangeRequestSheet` and by performing the same change as in the commit: https://github.com/xwiki-contrib/application-changerequest/commit/7565e720117f73102f5a276239eabfe85e15cff4.
