DescriptionGitHub Advisory

OpenProject is an open-source, web-based project management software. Prior to 17.0.2, users with the Manage Users permission can lock and unlock users. This functionality should only be possible for users of the application, but they were not supposed to be able to lock application administrators. Due to a missing permission check this logic was not enforced. The problem was fixed in OpenProject 17.0.2The problem was fixed in OpenProject 17.0.2.

AnalysisAI

Insufficient permission validation in OpenProject prior to 17.0.2 allows users with the Manage Users permission to lock and unlock application administrators, a capability that should be restricted to administrators only. An authenticated attacker with user management privileges can exploit this to lock out admin accounts and potentially disrupt system administration capabilities. No patch is currently available for affected versions.
