Description
Group-Office before 6.8.181, 25.0.116, and 26.0.58 contains an arbitrary local file read vulnerability in FolderController::actionProcessUploadQueue that allows authenticated users to read server files by supplying absolute paths in the blobs parameter. Attackers can have files hard-linked or copied into their own folder and downloaded, exposing other users' stored files and config.php database credentials.
