Upstream fixed this in the commit “Fix remote-content blocker bypass via SVG SMIL `by` attribute”.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-184"],"references":["https://bugs.debian.org/1151279","https://github.com/roundcube/roundcubemail/commit/2b6ff79d8b14f94b0ff04765b7f02dbfdfe98efa","https://github.com/roundcube/roundcubemail/commit/96d993b4ac57166a094b5774f4761e0b905d9a05","https://github.com/roundcube/roundcubemail/releases/tag/1.6.20","https://github.com/roundcube/roundcubemail/releases/tag/1.7.5"],"products":[],"source":"nvd","synced_at":"2026-10-23T16:39:28.036610720+00:00"},"epss":{"cve":"CVE-2026-114729","score":0.00376,"percentile":0.31282,"date":"2026-10-25"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
