{"schema":"threatline.record/2","record":{"id":"CVE-2026-105688","aliases":["GHSA-mx4v-cmxq-644v"],"summary":"Penpot: Team admin can escalate to owner via team invitation (missing owner-role guard on the invitation path)","details":"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.","categories":["Unclassified"],"product":"penpot","vendor":"penpot","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-105688","source_modified_at":"2026-10-06T13:45:35.634Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"penpot","vendor":"penpot","versions":[{"version":"< 2.18.0","status":"affected"}],"defaultStatus":null},{"source":"GitHub Advisory Database","source_url":"https://github.com/penpot/penpot/security/advisories/GHSA-mx4v-cmxq-644v","source_modified_at":"2026-10-05T19:49:32Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"ecosystem":"","name":"penpot"},"range":"<2.18.0"}],"fixed_versions":[{"source":"GitHub Advisory Database","source_url":"https://github.com/penpot/penpot/security/advisories/GHSA-mx4v-cmxq-644v","source_modified_at":"2026-10-05T19:49:32Z","fetched_at":"2026-10-23T18:52:38.922436Z","package":{"ecosystem":"","name":"penpot"},"version":"2.18.0"}],"cvss":6.7,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00264,"percentile":0.17398,"score_date":"2026-10-23"},"published_at":"2026-10-05T19:50:01.439Z","modified_at":"2026-10-06T13:45:35.634Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-105688","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-06T13:45:35.634Z"},{"source":"GitHub Advisory Database","url":"https://github.com/penpot/penpot/security/advisories/GHSA-mx4v-cmxq-644v","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-10-05T19:49:32Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-105688","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","GitHub Advisory Database","EPSS"],"references":[{"source":"CVE List","url":"https://github.com/penpot/penpot/security/advisories/GHSA-mx4v-cmxq-644v","tags":["exploit"]},{"source":"CVE List","url":"https://github.com/penpot/penpot/commit/5efd9cc3c5689485322f57b644b83a3bd2e33cee","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/penpot/penpot/releases/tag/2.18.0","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"poc","automatable":"no","technical_impact":"total","assessed_at":"2026-10-06T13:44:53.635776Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-06T13:45:35.634Z","content_hash":"c3179f00a8ee66a48df01985c98826342d6ea3c4f4bc189223fbcf09fe0fe8c8"}}
