CVE-2026-105687 · Severity: medium · CVSS 4.9 · Published 2026-10-05

Penpot is an open-source design and prototyping platform where teams collaborate on files and projects. A non-owner team administrator could exploit a flaw in the delete-team-member function to remove the team owner's membership, permanently locking the owner out of their team and all associated projects, files, fonts, and media. This impacts team governance and access control for organizations using Penpot.

## How to fix

- Fixed in 2.18.0

## Technical details

The delete-team-member RPC command failed to validate that the target member is not the team owner before allowing removal by a non-owner administrator. An authenticated team admin can call this RPC to delete the owner's team-profile-rel membership without authorization checks, bypassing the existing protection present in update-team-member-role. The fix validates member existence and rejects deletion if the target is the owner and the caller is not the owner.
