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.

EchelonGraph scoreLOW confidence
This medium-severity CVE scores 4.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit-prediction score not yet available (the EPSS model rescores nightly; freshly-published CVEs typically appear within 48 hours). GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
