Overview

CVE-2026-105688 is a medium-severity vulnerability. It was published on October 5, 2026 and has a CVSS 3.1 base score of 6.7 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 6.7, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

Penpot is an open-source design and prototyping platform. Prior to 2.18.0, create-team-invitations and the invitation acceptance path allow a non-owner team administrator to assign the owner role because invitation roles are persisted and applied without the role-ceiling check used by update-team-member-role. An administrator can invite another account as an owner, create multiple owners, and then use the new owner account to obtain owner-only control over the team. This issue is fixed in version 2.18.0.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
