Impact
It's possible to execute any SQL query in Oracle by using the function like DBMS_XMLGEN or DBMS_XMLQUERY.
The XWiki#searchDocuments APIs are not sanitizing the query at all and even if they force a specific select, Hibernate allows using any native function in an HQL query (for example in the WHERE).
Patches
This has been patched in 16.10.6 and 17.3.0-rc-1.
Workarounds
There is no known workaround, other than upgrading XWiki.
