Details
As written in the advisory (Markdown source, shown as plain text).
### Impact
It's possible to make XWiki create many new schemas and fill them with tables just by using a crafted user identifier in the login form.
### Patches
The problem has been patched in XWiki 13.10.8, 14.6RC1 and 14.4.2.
### Workarounds
The only workarounds for this are:
* use an authenticator which does interpret the login as a reference to a document
* using a different database than PostgreSQL
* upgrade XWiki
