NextCloud Server and NextCloud Enterprise Server provide file storage for Nextcloud, a self-hosted productivity platform. In NextCloud Server versions 25.0.0 until 25.0.7 and 26.0.0 until 26.0.2 and Nextcloud Enterprise Server versions 21.0.0 until 21.0.9.12, 22.0.0 until 22.2.10.12, 23.0.0 until 23.0.12.7, 24.0.0 until 24.0.12.2, 25.0.0 until 25.0.7, and 26.0.0 until 26.0.2, when two server are registered as trusted servers for each other and successfully exchanged the share secrets, the malicious server could modify or delete VCards in the system addressbook on the origin server. This would impact the available and shown information in certain places, such as the user search and avatar menu. If a manipulated user modifies their own data in the personal settings the entry is fixed again. Nextcloud Server n 25.0.7 and 26.0.2 and Nextcloud Enterprise Server 21.0.9.12, 22.2.10.12, 23.0.12.7, 24.0.12.2, 25.0.7, and 26.0.2 contain a patch for this issue. A workaround is available. Remove all trusted servers in the "Administration" > "Sharing" settings `…/index.php/settings/admin/sharing`. Afterwards, trigger a recreation of the local system addressbook with the following `occ dav:sync-system-addressbook`.解决建议
"将组件 nextcloud_server 升级至 22.2.10.12 及以上版本""将组件 nextcloud_server 升级至 23.0.12.7 及以上版本""将组件 nextcloud_server 升级至 24.0.12.2 及以上版本""将组件 nextcloud_server 升级至 20.0.14.14 及以上版本""将组件 nextcloud_server 升级至 19.0.13.9 及以上版本""将组件 nextcloud_server 升级至 26.0.2 及以上版本""将组件 nextcloud_server 升级至 25.0.7 及以上版本""将组件 nextcloud_server 升级至 21.0.9.12 及以上版本"
