org.xwiki.platform:xwiki-platform-user-profile-ui is missing authorization to enable or disable users. Any user (logged in or not) with access to the page XWiki.XWikiUserProfileSheet can enable or disable any user profile. This might allow to a disabled user to re-enable themselves, or to an attacker to disable any user of the wiki. The problem has been patched in XWiki 13.10.7, 14.5RC1 and 14.4.2. Workarounds: The problem can be patched immediately by editing the page XWiki.XWikiUserProfileSheet
in the wiki and by performing the changes contained in https://github.com/xwiki/xwiki-platform/commit/5be1cc0adf917bf10899c47723fa451e950271fa.
The product does not perform an authorization check when an actor attempts to access a resource or perform an action.

Assuming a user with a given identity, authorization is the process of determining whether that user can access a given resource, based on the user’s privileges and any permissions or other access-control specifications that apply to the resource. When access control checks are not applied, users are able to access data or perform actions that they should not be allowed to perform. This can lead to a wide range of problems, including information exposures, denial of service, and arbitrary code execution.
