**Name of the Vulnerable Software and Affected Versions** XWiki versions 1.8.1 through 14.10.21 XWiki versions 15.0-rc-1 through 15.10.11 XWiki versions 16.0.0-rc-1 through 16.4.2 XWiki versions 16.5.0-rc-1 through 16.6.x **Description** The issue allows anyone to access the metadata of any attachment in the wiki using the wiki attachment REST endpoint. There is no filtering for the results depending on current user rights, meaning an unauthenticated user could exploit this even in a private wiki. **Recommendations** For versions 1.8.1 through 14.10.21, update to version 14.10.22 or later. For versions 15.0-rc-1 through 15.10.11, update to version 15.10.12 or later. For versions 16.0.0-rc-1 through 16.4.2, update to version 16.4.3 or later. For versions 16.5.0-rc-1 through 16.6.x, update to version 16.7.0 or later.
