Description

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, the delete-team-member RPC allows a team administrator to remove any member other than themselves but does not protect the team owner. A non-owner administrator can delete the owner's team-profile-rel membership and lock the owner out of the team and its projects, files, fonts, and media. This issue is fixed in version 2.18.0.
