GHSA-vvp7-r422-rx83

Summary: Unauthenticated user can have information about hidden users on subwikis through uorgsuggest.vm

Details: ### Impact It's possible to list some users who are normally not viewable from subwiki by requesting users on a subwiki which allows only global users with `uorgsuggest.vm`. This issue only concerns hidden users from main wiki. Note that the disclosed information are the username and the first and last name of users, no other information is leaked. ### Patches The problem has been patched on XWiki 13.10.8, 14.4.3 and 14.7RC1. ### Workarounds It's possible to workaround this vulnerability by patching directly `uorgsuggest.vm ` to apply the same changes as in https://github.com/xwiki/xwiki-platform/pull/1883. ### References * JIRA ticket: https://jira.xwiki.org/browse/XWIKI-20007 * this vulnerability is actually a remaining of https://github.com/xwiki/xwiki-platform/security/advisories/GHSA-97jg-43c9-q6pf which wasn't entirely fixed back then ### For more information If you have any questions or comments about this advisory: * Open an issue in [Jira](https://jira.xwiki.org) * Email us at [security ML](mailto:[email protected])
