Prior to 2.18.0, app.util.ssrf/blocked-address? relies on Java InetAddress predicates that do not classify NAT64, 6to4, or Teredo addresses and applies additional CIDR checks only to IPv4 values. Exploitation requires routing through a NAT64 gateway or an attacker-controlled DNS AAAA record; cloud environments with NAT64 gateways are directly exploitable. A user controlling a media import URL, or an administrator controlling a webhook URL, can then supply an IPv6 transition address that embeds a cloud-metadata, loopback, link-local, or private IPv4 target and bypasses the intended SSRF restrictions. Media import can disclose response bodies, while webhook delivery can expose response status as a network-probing side channel. This issue is fixed in version 2.18.0.","state":0,"publishedAt":"2026-10-05T19:51:04.208+00:00","modifiedAt":"2026-10-08T02:23:53.207+00:00","affected":[{"ecosystem":"Vendor product","name":"penpot","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"penpot\",\n                    \"product\": \"penpot\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 2.18.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:L/UI:N/VC:H/VI:N/VA:L/SC:N/SI:N/SA:N","score":6,"severity":"MEDIUM"}],"references":["https://github.com/penpot/penpot/security/advisories/GHSA-wxgm-8qjw-x445","https://github.com/penpot/penpot/commit/326d83e780ae120b45ccd6f3d7bd24922b54461c","https://github.com/penpot/penpot/releases/tag/2.18.0"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-105689","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-105689","identifiers":["CVE-2026-105689"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
