{"id":"CVE-2026-114717","details":"Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a mail header injection vulnerability when a message is forwarded as an attachment. The subject of the forwarded message was used verbatim to generate the attachment name, so a received message whose subject contains CRLF sequences could inject arbitrary MIME part headers into the outgoing message. Upstream fixed this in the commit “Fix mail header injection via subject of a message forwarded as attachment”, which collapses whitespace in the generated name.","modified":"2026-10-23T02:45:36.218376436Z","published":"2026-10-22T01:21:14.794Z","database_specific":{"cna_assigner":"mitre","cwe_ids":["CWE-99"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/114xxx/CVE-2026-114717.json"},"references":[{"type":"REPORT","url":"https://bugs.debian.org/1151279"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/114xxx/CVE-2026-114717.json"},{"type":"WEB","url":"https://github.com/roundcube/roundcubemail/"},{"type":"FIX","url":"https://github.com/roundcube/roundcubemail/commit/4c3291ce9df9e1d3b45330d0854d65cd8efbeee9"},{"type":"FIX","url":"https://github.com/roundcube/roundcubemail/commit/c325953a251d0132f1909569b3eac0b974095dd4"},{"type":"FIX","url":"https://github.com/roundcube/roundcubemail/releases/tag/1.6.20"},{"type":"FIX","url":"https://github.com/roundcube/roundcubemail/releases/tag/1.7.5"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-114717"},{"type":"ADVISORY","url":"https://roundcube.net/news/2026/10/19/security-updates-1.6.20-and-1.7.5"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/roundcube/roundcubemail","events":[{"introduced":"993b888afe29c383bf45c84f17090f4db96367ba"},{"fixed":"1dd910522e73318447ed6e20bed1efd7adeb240a"},{"introduced":"df9effa186f81d676962b941da4ebab5e05c3088"},{"fixed":"26d1b077f0c910a16c44c1862fe26e15f0bb3685"},{"fixed":"4c3291ce9df9e1d3b45330d0854d65cd8efbeee9"},{"fixed":"c325953a251d0132f1909569b3eac0b974095dd4"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"1.6.0"},{"fixed":"1.6.20"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"},{"source":"AFFECTED_FIELD","strategy":"StandardRange","range":[{"introduced":"1.7.0"},{"fixed":"1.7.5"}]},{"range":[{"fixed":"4c3291ce9df9e1d3b45330d0854d65cd8efbeee9"}],"source":"REFERENCES_COMMIT"},{"original_tag":"1.7.5","range":[{"fixed":"26d1b077f0c910a16c44c1862fe26e15f0bb3685"}],"source":"REFERENCES_TAG"},{"original_tag":"1.6.20","range":[{"fixed":"1dd910522e73318447ed6e20bed1efd7adeb240a"}],"source":"REFERENCES_TAG"},{"range":[{"fixed":"c325953a251d0132f1909569b3eac0b974095dd4"}],"source":"REFERENCES_COMMIT"}]}}],"versions":["1.7.4","1.6.19","1.7.3","1.6.18","1.6.17","1.7.2","1.6.16","1.7.1","1.7.0","1.6.15","1.6.14","1.6.13","1.6.12","1.6.11","1.6.10","1.6.9","1.6.8","1.6.7","1.6.6","1.6.5","1.6.4","1.6.3","1.6.2","1.6.1","1.6.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-114717.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:L/A:N"}]}
