Pydio Cells 4.1.2 Privilege Escalation
Posted on 30 May 2023
Pydio Cells versions 4.1.2 and below suffer from a privilege escalation vulnerability. It allows users, by default, to create so-called external users in order to share files with them. By modifying the HTTP request sent when creating such an external user, it is possible to assign the new user arbitrary roles. By assigning all roles to a newly created user, access to all cells and non-personal workspaces is granted.
