{"id":"DEBIAN-CVE-2026-114730","details":"Roundcube Webmail 1.6.14 before 1.6.20 and 1.7.0 before 1.7.5 is affected by a server-side request forgery filter bypass. The network blocklist used by rcube_utils::is_local_url() omitted the RFC 6052 NAT64 prefix 64:ff9b::/96, the RFC 8215 local-use NAT64 prefix 64:ff9b:1::/48 and the unspecified address ::/128, so URLs such as http://[64:ff9b::7f00:1]/ passed the filter and reached loopback, link-local and cloud metadata addresses. Upstream fixed this in the commit “Fix SSRF filter (is_local_url()) bypass via NAT64 64:ff9b::/96”.","modified":"2026-10-22T10:00:09.977522164Z","published":"2026-10-22T09:47:32.028740489Z","upstream":["CVE-2026-114730"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-114730"}],"affected":[{"package":{"name":"roundcube","ecosystem":"Debian:12","purl":"pkg:deb/debian/roundcube?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.1+dfsg-1","1.6.10+dfsg-1","1.6.10+dfsg-2","1.6.11+dfsg-1","1.6.12+dfsg-1","1.6.13+dfsg-1","1.6.14+dfsg-1","1.6.15+dfsg-1","1.6.16+dfsg-1","1.6.17+dfsg-1","1.6.18+dfsg-1","1.6.19+dfsg-1","1.6.2+dfsg-1","1.6.20+dfsg-1","1.6.3+dfsg-1","1.6.3+dfsg-1~deb12u1","1.6.3+dfsg-2","1.6.4+dfsg-1","1.6.4+dfsg-1~deb12u1","1.6.5+dfsg-1","1.6.5+dfsg-1+deb12u10","1.6.5+dfsg-1+deb12u11","1.6.5+dfsg-1+deb12u12","1.6.5+dfsg-1+deb12u2","1.6.5+dfsg-1+deb12u3","1.6.5+dfsg-1+deb12u4","1.6.5+dfsg-1+deb12u5","1.6.5+dfsg-1+deb12u6","1.6.5+dfsg-1+deb12u7","1.6.5+dfsg-1+deb12u8","1.6.5+dfsg-1+deb12u9","1.6.5+dfsg-1~deb12u1","1.6.6+dfsg-1","1.6.6+dfsg-2","1.6.7+dfsg-1","1.6.8+dfsg-1","1.6.8+dfsg-2","1.6.9+dfsg-1","1.6.9+dfsg-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-114730.json"}},{"package":{"name":"roundcube","ecosystem":"Debian:13","purl":"pkg:deb/debian/roundcube?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.11+dfsg-1","1.6.12+dfsg-0+deb13u1","1.6.12+dfsg-1","1.6.13+dfsg-0+deb13u1","1.6.13+dfsg-1","1.6.14+dfsg-1","1.6.15+dfsg-0+deb13u1","1.6.15+dfsg-1","1.6.16+dfsg-0+deb13u1","1.6.16+dfsg-1","1.6.17+dfsg-0+deb13u1","1.6.17+dfsg-1","1.6.18+dfsg-0+deb13u1","1.6.18+dfsg-1","1.6.19+dfsg-0+deb13u1","1.6.19+dfsg-1","1.6.20+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-114730.json"}},{"package":{"name":"roundcube","ecosystem":"Debian:14","purl":"pkg:deb/debian/roundcube?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.6.20+dfsg-1"}]}],"versions":["1.6.11+dfsg-1","1.6.12+dfsg-1","1.6.13+dfsg-1","1.6.14+dfsg-1","1.6.15+dfsg-1","1.6.16+dfsg-1","1.6.17+dfsg-1","1.6.18+dfsg-1","1.6.19+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-114730.json"}}],"schema_version":"1.9.0"}
