{"id":"CVE-2026-114717","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-114717","generatedAt":"2026-10-27T23:50:48.080Z","title":"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.","description":"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.","published":"2026-10-22T02:16:59.000Z","lastModified":"2026-10-26T20:17:50.000Z","status":"Undergoing Analysis","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:L/A:N"},"cwe":["CWE-99"],"affected":[],"epss":{"score":0.00299,"percentile":0.22356,"date":"2026-10-26","history":[{"date":"2026-10-22","score":0.00298,"percentile":0.21345}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.30%).
