Upgrade org.xwiki.platform:xwiki-platform-oldcore to version 14.10.8, 15.3-rc-1 or higher.
Overview
org.xwiki.platform:xwiki-platform-oldcore is a generic wiki platform offering runtime services for applications built on top of it.
Affected versions of this package are vulnerable to Incorrect Authorization. When a document has been deleted and re-created, it is possible for users with view rights on the re-created document but not on the deleted document to view the contents of the deleted document. This can be exploited through the diff feature and, partially, through the REST API by using versions such as deleted:1, using predictable sequential numbers.
Workaround
Exposure to this vulnerability can be limited by regularly cleaning deleted documents. Extra care should be taken when deleting sensitive documents that are protected individually (and not, e.g., by being placed in a protected space) or deleting a protected space as a whole.
