# Group-Office: authenticated users can read arbitrary server files

Link for people: https://infrastack.ai/live/CVE-2026-125390 (this .md is for agents)

Group-Office, a groupware suite, lets any logged-in user read files from the server by passing absolute paths to an upload queue endpoint. An attacker can read other users' stored files and config.php, which holds database credentials.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

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.
