CVE-2023-29203Public exploitNetwork attack vector

Hidden-user disclosure via misresolved access-control reference

Published Apr 15, 2023 · Updated Feb 6, 2025

Information disclosure in XWiki Platform allows remote attackers to list hidden main-wiki users through a subwiki suggestion request. The uorgsuggest.vm template checks view access against a user reference resolved in the current subwiki instead of the user's home wiki. A reachable subwiki configured for global-only users is required, and exposure is limited to usernames and first and last names of hidden main-wiki users.
