{"id":"CVE-2026-114725","details":"Roundcube Webmail before 1.6.20 and 1.7.x before 1.7.5 is affected by a mail header injection vulnerability. rcmail_sendmail stripped newline characters only from the Subject and Organization headers, leaving other header values taken from request parameters unsanitized, so a remote authenticated attacker could inject arbitrary headers into an outgoing message via the References, In-Reply-To, Message-ID and From parameters. Upstream fixed this in the commit “Fix mail header injection via References/In-Reply-To/Message-ID/From parameters”, which normalizes whitespace in every string header value.","modified":"2026-10-22T10:45:50.083791229Z","published":"2026-10-22T01:52:10.894Z","database_specific":{"unresolved_ranges":[{"extracted_events":[{"range":[{"introduced":"1.6.0"},{"fixed":"1.6.20"},{"introduced":"1.7.0"},{"fixed":"1.7.5"}],"source":"AFFECTED_FIELD","strategy":"StandardRange"}]},{"extracted_events":[{"range":[{"introduced":"1.6.0"},{"fixed":"1.6.20"},{"introduced":"1.7.0"},{"fixed":"1.7.5"}],"source":"CPE_FIELD","strategy":"CPEApplicability"}]},{"extracted_events":[{"range":[{"fixed":"1.6.20"},{"introduced":"1.7.x"},{"fixed":"1.7.5"}],"source":"DESCRIPTION"}]}],"cna_assigner":"mitre","cwe_ids":["CWE-99"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/114xxx/CVE-2026-114725.json"},"references":[{"type":"REPORT","url":"https://bugs.debian.org/1151279"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/114xxx/CVE-2026-114725.json"},{"type":"WEB","url":"https://github.com/roundcube/roundcubemail/"},{"type":"FIX","url":"https://github.com/roundcube/roundcubemail/commit/79adcfc0c48012bbbe930278471425027fd7331c"},{"type":"FIX","url":"https://github.com/roundcube/roundcubemail/commit/acd32a86f631dd6dcda8ac3ec7bd9ba4d4c0c117"},{"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-2026-114725"},{"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":"0"},{"fixed":"acd32a86f631dd6dcda8ac3ec7bd9ba4d4c0c117"},{"fixed":"26d1b077f0c910a16c44c1862fe26e15f0bb3685"},{"fixed":"1dd910522e73318447ed6e20bed1efd7adeb240a"},{"fixed":"79adcfc0c48012bbbe930278471425027fd7331c"}],"database_specific":{"extracted_events":[{"range":[{"fixed":"acd32a86f631dd6dcda8ac3ec7bd9ba4d4c0c117"}],"source":"REFERENCES_COMMIT"},{"range":[{"fixed":"26d1b077f0c910a16c44c1862fe26e15f0bb3685"}],"source":"REFERENCES_TAG","original_tag":"1.7.5"},{"source":"REFERENCES_TAG","original_tag":"1.6.20","range":[{"fixed":"1dd910522e73318447ed6e20bed1efd7adeb240a"}]},{"source":"REFERENCES_COMMIT","range":[{"fixed":"79adcfc0c48012bbbe930278471425027fd7331c"}]}]}}],"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","1.7-rc6","1.6.15","1.7-rc5","1.6.14","1.7-rc4","1.6.13","1.7-rc3","1.7-rc2","1.6.12","1.7-rc","1.7-beta2","1.7-beta","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","1.6-rc","1.6-beta","1.5-rc","1.5-beta","1.4-rc2","1.4-rc1","1.4-beta","1.3-beta","1.2-rc","1.2-beta","1.1.0","1.1-rc","1.1-beta","v0.1-beta2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-114725.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:L/A:N"}]}
