Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The xwiki-platform-oldcore package (Maven org.xwiki.platform:xwiki-platform-oldcore) is affected in versions from 1.0 up to 15.10.16, from 16.0.0-rc-1 up to 16.4.7, and from 16.5.0-rc-1 up to 16.10.2 when XWiki runs on Oracle. An attacker who can send requests to the REST API query endpoint can inject SQL and run arbitrary queries against the Oracle database. Upgrade to 15.10.16, 16.4.7, or 16.10.2; the source lists no workaround other than upgrading.
