Impact
Any user can exploit the WikiManager REST API to create a new wiki, where the user could become an administrator and so performs other attacks on the farm. Note that this REST API is not bundled in XWiki Standard by default: it needs to be installed manually through the extension manager.
Patches
The problem has been patched in versions 15.10.15, 16.4.6 and 16.10.0 of the REST module.
Workarounds
There's no workaround other than upgrading the dependency.
