Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

XWiki's xwiki-platform-rest-server (Maven org.xwiki.platform:xwiki-platform-rest-server) is affected in versions 1.8.1 up to 14.10.22, 15.0-rc-1 up to 15.10.12, 16.0.0-rc-1 up to 16.4.3, and 16.5.0-rc-1 up to 16.7.0. The REST endpoint for wiki attachments does not filter results by user rights, so an unauthenticated user can list attachments and read their metadata even on a private wiki. Upgrade to 14.10.22, 15.10.12, 16.4.3, or 16.7.0. No workaround other than upgrading is listed.
