Summary

Penpot before 2.18.0 does not protect the team owner from removal by team administrators. The delete-team-member RPC lets a team administrator remove any member except themselves, including the owner, which is an incorrect authorization flaw (CWE-863). A non-owner administrator with high privileges can lock the owner out of the team and its projects, files, fonts and media.

Description from the CNA

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.
